Applitools Eyes

Applitools Eyes SDK for webdriver.io

npm


Table of contents

Installation

Install Eyes-WebdriverIO as a local dev dependency in your tested project:

npm i -D @applitools/eyes-webdriverio

Applitools API key

In order to authenticate via the Applitools server, you need to supply the Eyes-WebdriverIO SDK with the API key you got from Applitools. Read more about how to obtain the API key here.

To do this, set the environment variable APPLITOOLS_API_KEY to the API key before running your tests. For example, on Linux/Mac:

export APPLITOOLS_API_KEY=<your_key>
npx wdio wdio.conf.js

And on Windows:

set APPLITOOLS_API_KEY=<your_key>
npx wdio wdio.conf.js

It's also possible to set the API key programmatically like so:

eyes.setApiKey('<your API key>')

Usage

After defining the API key, you will be able to use commands from Eyes-WebdriverIO in your webdriver.io tests to take screenshots and use Applitools Eyes to manage them.

For example:

const {Eyes, Target} = require('@applitools/eyes-webdriverio')
 
describe('My first visual test', function() {
  it('should check the webdriver.io website', async function() {
    browser.get('https://webdriver.io');
 
    const eyes = new Eyes();
    await eyes.open(browser, "webdriver.io website", "My first webdriver.io test!")
    await eyes.check('home page', Target.window().fully())
    await eyes.close()
  });
});

Getting started with the API

Eyes constructor

Creates an instance of Eyes, which then exposes methods to run and configure visual tests.

const eyes = new Eyes(runner)
  • runner - A runner instance which manages tests across multiple Eyes instances. The runner can be an instance of either a ClassicRunenr or a VisualGridRunner. For more information, see the Runners section below.

open

Creates an Applitools test. This will start a session with the Applitools server.

eyes.open(browser, appName, testName, viewportSize)

Visual tests and baselines

By using the open/check/close methods on Eyes, you are creating visual tests in Applitools Eyes. A visual test is a sequence of screenshots, compared with a baseline. The baseline is also a sequence of screenshots. The specific baseline to compare against is found by using the values for:

  1. Browser
  2. Operating system
  3. App name
  4. Test name
  5. Viewport size

The baseline is created automatically when running a test with specific values for these 5 parameters for the first time. For example, you run a test with Chrome on OS X and specify the app name, test name and viewport size via eyes.open(t, 'some app', 'some test', {width: 1200, height: 800}). The first time the test runs with these parameters, a baseline will be created. Any subsequent execution with the same values will compare screenshots against this baseline. The test will actually be created after running eyes.close, and the results of the test are returned as a TestResults object.

For more information, visit our documentation page: https://applitools.com/docs/topics/general-concepts/how-eyes-compares-checkpoints.html

Batches

It's possible to aggregate tests that are run in different processes, or in different Eyes instances, under the same batch. This is done by providing the same batch ID to these tests.

For instructions, see the Organize tests in batches section below.

For more information, visit our documentation page: https://applitools.com/docs/topics/working-with-test-batches/working-with-test-batches-in-overview.html

check

Generates a screenshot of the current page and add it to the Applitools Test.

eyes.check(tag, checkSettings)

Arguments to eyes.check

tag

Defines a name for the checkpoint in the Eyes Test Manager. The name may be any string and serves to identify the step to the user in the Test manager. You may change the tag value without impacting testing in any way since Eyes does not use the tag to identify the baseline step that corresponds to the checkpoint - Eyes matches steps based on their content and position in the sequences of images of the test. See How Eyes compares checkpoints and baseline images for details.

checkSettings

Holds the checkpoint's configuration. This is defined using a fluent API, starting with Target.

Page screenshot
  • For taking a viewport screenshot, call Target.window().
  • For a full page screenshot, call Target.window().fully().
Region screenshot

To take an element screenshot, it's possible to specify either a locator or the element representation itself. For example:

const locator = by.css('.banner')
eyes.check('region by locator', Target.region(locator))
 
const el = element(locator)
eyes.check('region by element', Target.region(el))

Passing a string is interpreted as a css selector:

eyes.check('region by css selector', Target.region('.banner'))

It's also possible to specify the absolute coordinates for the desired region:

eyes.check('region by coordinates', Target.region({
  left: 10,
  top: 20,
  width: 200,
  height: 80
}))

For all the above options, it's possible to specify .fully() in order to take the entire content of an element that can be scrolled.

Switching into frames

For taking screenshots of elements inside iframes, it's possible to specify the frame using the Target.frame fluent API. For example:

eyes.check('element inside frame', Target.frame('frame-1').region(by.css('.element-inside frame')))

It's possible to take a screenshot of the entire frame:

eyes.check('entire frame', Target.frame('frame-1').fully())

Multiple frame calls can be made, thus creating a "frame chain". For example:

eyes.check('element inside nested frames', Target.frame('frame-1').frame('frame-1-1').region(by.css('.nested-element')))
Ignore Regions
eyes.check('viewport screenshot with ignore region', Target.window().ignoreRegion('.dynamic-content-here'))

Possible input types are:

  • string (interpreted as css selector)
  • by locator
  • element
  • coordinates ({left, top, width, height})
Floating Regions
eyes.check(
  'viewport screenshot with floating region',
  Target.window().floatingRegion('.floating-area', 10, 10, 10, 10)) // up, down, left, right

Possible input types are:

  • string (interpreted as css selector)
  • by locator
  • element
  • coordinates ({left, top, width, height})
Content/Strict/Layout Regions
eyes.check('viewport screenshot with content region', Target.window().contentRegion('.some-element'))
 
eyes.check('viewport screenshot with strict region', Target.window().strictRegion('.some-element'))
 
eyes.check('viewport screenshot with layout region', Target.window().layoutRegion('.some-element'))

Possible input types are:

  • string (interpreted as css selector)
  • by locator
  • element
  • coordinates ({left, top, width, height})
Accessiblity Regions
const {AccessibilityRegionType} = require('@applitools/eyes-webdriverio')
 
eyes.check(
  'viewport screenshot with accessibility region',
  Target.window().accessibilityRegion('.some-element', AccessibilityRegionType.LargeText)
)

Possible input types are:

  • string (interpreted as css selector)
  • by locator
  • element
  • coordinates ({left, top, width, height})
Scroll root element
eyes.check(
  'full page with custom scroll root element',
  Target.window().fully().scrollRootElement('.main-content')
)

Possible input types are:

  • string (interpreted as css selector)
  • by locator
  • element
Other checkSettings configuration
  • hideScrollbars
  • hideCaret
  • ignoreDisplacements
  • useDom
  • enablePatterns
  • withName

close

Closes the applitools test and check that all screenshots are valid.

It is important to call this at the end of each test, symmetrically to open(or in afterEach(), see Best practice for using the SDK).

const testResults = await eyes.close(throwEx)
  • throwEx - (Boolean) throw an error if visual differences were found, or if the test failed for any other reason. The deault is true.

Return value: TestResults.

Runners

There are two types of runners: ClassicRunner and VisualGridRunner:

  1. ClassicRunner - used when the screenshot is taken by the SDK itself.
const {ClassicRunner} = require('@applitools/eyes-webdriverio')
const runner = new ClassicRunner()
  1. VisualGridRunner - used when the screenshot is taken by the Ultrafast grid.
const {VisualGridRunner} = require('@applitools/eyes-webdriverio')
const runner = new VisualGridRunner(concurrentSessions)
  • concurrentSessions - (Number) the number of visual tests that are allowed to run at the same time. Default: 1.

Purpose of runners

There are two purposes for using runners:

1. Use the Ultrafast grid

This is done simply by specifying the VisualGridRunner. Browsers are specified by using the Configuration API. For example:

const {Eyes, VisualGridRunner, BrowserType, DeviceName} = require('@applitools/eyes-webdriverio')
const eyes = new Eyes(new VisualGridRunner)
const configuration = eyes.getConfiguration()
 
configuration.addBrowser({width: 1200, height: 800, name: BrowserType.CHROME})
configuration.addBrowser({width: 1200, height: 800, name: BrowserType.FIREFOX})
configuration.addBrowser({width: 1200, height: 800, name: BrowserType.SAFARI})
configuration.addBrowser({width: 1200, height: 800, name: BrowserType.EDGE})
configuration.addBrowser({width: 1200, height: 800, name: BrowserType.IE_11})
configuration.addBrowser({deviceName: DeviceName.Galaxy_S9_Plus})
 
eyes.setConfiguration(configuration)

2. Manage tests across multiple Eyes instances

If you decide to create more than one instance of Eyes in your tests (for example, if you run new Eyes() in beforeEach test hooks), the runner provides a method called getAllTestResults for collecting test results across all eyes instances.

Consider the following:

const {Eyes, ClassicRunner, StitchMode} = require('applitools/eyes-webdriverio')
const runner = new VisualGridRunner(10)
 
async function runTest(url, ...browsers) {
  await driver.get(url)
  const eyes = new Eyes(runner)
  const configuration = eyes.getConfiguration()
  configuration.addBrowsers(...browsers)
  eyes.setConfiguration(configuration)
  await eyes.open(driver, appName, testName, viewportSize)
  await eyes.check(undefined, Target.window().fully())
  eyes.close()
}
 
async function collectResults() {
  const testResultsSummary = await runner.getAllTestResults()
  for (const testResultContainer of testResultsSummary) {
    const testResults = testResultContainer.getTestResults()
    console.log(formatTestResults(testResults)) // see the Recipes section below for the implementation of this function
  }
}
 
Promise.all([
  runTest('https://example.org',
    {width: 1200, height: 800, name: BrowserType.CHROME},
    {width: 1200, height: 800, name: BrowserType.FIREFOX}
  ),
  runTest('https://applitools.com',
    {deviceName: DeviceName.Galaxy_S9_Plus},
    {deviceName: DeviceName.iPhone_X}
  )
]).then(collectResults)

This snippet of code runs two visual tests in parallel on two websites, using a specific configuration for each url. To achieve this, multiple Eyes instances are used, but in order to wait for all test results, we call runner.getAllTestResults. We then iterate through the results and print out a formatted summary.

Using the SDK as a service

What is the service?

As users of webdriver.io, you may choose to use the SDK directly. However, webdriver.io provides an addon mechanism called Services, which makes it possible to reduce boilerplate code and simplify test logic. Read more about it here.

Eyes-WebdriverIO can be used as a webdriver.io service. Using the service provides several boilerplate operations and default values, and lets you concentrate on the core logic.

What is the difference from just using the SDK directly?

Here are the main differences between the service and the SDK:

  1. No need to call eyes.open and eyes.close. Only eyes.check (or its service equivalent, browser.eyesCheck) is needed. The open and close calls are made between different it's, so each functional test that contains visual checkpoints will appear in Eyes dashboard separately.

  2. No need to specify testName and appName in the configuration. These values are automatically extracted from the it's and describe's. The default test name is the containing it, and the default app name is the it's containing describe.

    For more information, see Override testName and appName section.

  3. No need to instantiate the Eyes class. It is instantiated for you, and configured appropriately from wdio.conf.js.

  4. Receiving batch completion notifications when test execution is done. See Batch completion notifications.

How to use the service

First, add Eyes-WebdriverIO to your configuration as a service. Add the following to your webdriver.io configuration file:

const {EyesService} = require('@applitools/eyes-webdriverio')
 
exports.config = {
  // ...
  services: [[EyesService, {
    // webdriver.io version 6: Eyes service configuration here
  }]],
  // ...
  eyes: {
    // webdriver.io version 5: Eyes service configuration here
  }
}

There's a difference where configuration of the service needs to be, depending on the webdriver.io version you use. See more information in the webdriver.io blog.

Configure the service

Every configuration parameter that exists in the configuration for Applitools' Eyes SDK for webdriver.io can be specified in the wdio.conf.js file (or any other webdriver.io configuration file specified by the user).

For example:

exports.config = {
  // In webdriver.io 6:
  services: [[EyesService, {
    viewportSize: {width: 1200, height: 800},
    matchLevel: 'Layout',
    matchTimeout: 0,
    batch: {name: 'This will appear as the batch name in Eyes dashboard'},
    // ...
  }]],
}

For more information, visit our documentation page: https://applitools.com/docs/api/eyes-sdk/index-gen/class-configuration-webdriverio_sdk5-javascript.html

Running with the Ultrafast grid

To run tests with the Ultrafast grid, specify the following in the wdio.conf.js file:

exports.config = {
  eyes: {
    useVisualGrid: true,
    // ...
  }
}

To specify which viewport sizes and browsers to render on the Ultrafast grid, use the browsersInfo entry in the configuration. For example:

exports.config = {
  eyes: {
    useVisualGrid: true,
    browsersInfo: [
      {width: 1200, height: 800, name: 'chrome'},
      {width: 1200, height: 800, name: 'firefox'},
      {width: 1200, height: 800, name: 'safari'},
      {width: 1200, height: 800, name: 'edgechromium'}
      {width: 1200, height: 800, name: 'ie'}
      {deviceName: 'Galaxy S9 Plus'}
    ]
    // ...
  }
}

Verbose logging

For troubleshooting, it is possible to enable versbose logging by specifying the following in the wdio.conf.js file:

exports.config = {
  // ...
  enableEyesLogs: true,
  // ...
}

Override testName and appName

Here's an example for overriding the default values:

const configuration = browser.eyesGetConfiguration()
configuration.setAppName('<YOUR_APP_NAME>')
configuration.setTestName('<YOUR_TEST_NAME>')
browser.eyesSetConfiguration(configuration)

Batch completion notifications

Here's how to setup batch notifications:

// wdio.conf.js
 
exports.config = {
  // ...
  eyes: {
    batch: {notifyOnCompletion: true}
  }
  // ...
}

For more information about batch notifications, and the remaining steps required to setup notifications, see https://applitools.com/docs/features/batch-completion-notifications.html.

Using the service API

browser.eyesCheck(tag, checkSettings)

Generates a screenshot of the current page and adds it to the Applitools Test. See the eyes.check section for more details about the arguments.

browser.eyesGetTestResults()

Close the current visual test and return the test results. For example:

describe('webdriver.io page', () => {
  it('is visually perfect', () => {
    browser.url('https://webdriver.io')
    browser.eyesCheck('homepage')
    $('a[href="/docs/gettingstarted.html"]').click()
    browser.eyesCheck('getting started page')
    const testResults = browser.eyesGetTestResults()
 
    // example for using the testResults -
    // fail the test if visual differences were found
    if (testResults.getStatus() !== 'Passed') {
      const testName = `'${testResults.getName()}' of '${testResults.getAppName()}'`
      throw new Error(`Test ${testName} detected differences! See details at: ${testResults.getUrl()}`)
    }
  })
})

For more information, visit our documentation page: https://applitools.com/docs/api/eyes-sdk/index-gen/class-testresults-webdriverio_sdk5-javascript.html

browser.eyesSetScrollRootElement(selector)

Sets the scroll root element to a specific element on the page. This is the element that will be scrolled when taking a full page screenshot.

For example:

browser.eyesSetScrollRootElement('.container')

browser.eyesSetConfiguration(configuration)

Sets a new configuration for the underlying Eyes instance. This will override the configuration specified in the wdio.conf.js file for the remainder of test execution.

For example, see the Override testName and appName section.

browser.eyesGetConfiguration()

Gets the configuration object that's defined for the underlying Eyes instance.

For example, see the Override testName and appName section.

browser.eyesAddProperty(key, value)

Adds a custom key name/value property that will be associated with your tests. You can view these properties and filter and group by these properties in the Test Manager

browser.eyesClearProperties()

Clears any custom key name/value properties.

Recipes for common tasks

Configure Server URL

By default, Eyes-WebdriverIO communicates with Applitools' public Eyes cloud server, located at https://eyesapi.applitools.com.

If you have a dedicated cloud or an on-premise server, configure a different Eyes server URL as follows:

eyes.setServerUrl('https://mycompanyeyesapi.applitools.com')

Configure Proxy

If your company's network requires requests to go through the corporate proxy, you may configure it as follows:

eyes.setProxy('http://yourproxy.com')
 
// provide username and password:
eyes.setProxy('http://user:pass@yourproxy.com')
// OR
eyes.setProxy({
  url: 'https://yourproxy.com',
  username: 'user',
  password: 'pass'
})
 
// use tunneling in case of HTTP over HTTPS proxy:
eyes.setProxy({
  url: 'http://yourproxy.com',
  isHttpOnly: true
})

Make every visual test correspond to a webdriver.io test

Every call to eyes.open and eyes.close defines a test in Applitools Eyes, and all the calls to eyes.check between them are called "steps". In order to get a test structure in Applitools that corresponds to the test structure in webdriver.io, it's best to open/close tests in every test call.

For example, when running with Mocha as a test runner:

describe('My first visual test', function() {
  beforeEach(async () => {
    await eyes.open(browser, "webdriver.io website", "My first webdriver.io test!")
  })
  afterEach(async () => {
    await eyes.close()
  })
  it('...', async function() {
    // ...
  });
});

Organize tests in batches

It's possible to manage how visual tests are aggregated into batches. Here are two methods for clustering tests into a single batch:

Method 1: environment variable

Run all the processes that execute webdriver.io with the same value for APPLITOOLS_BATCH_ID. For example, execute all webdriver.io files specified in the configuration file wdio.conf.js with the same randomly generated UUID:

#! Unix based machines: 
APPLITOOLS_BATCH_ID=`uuidgen` npx wdio wdio.conf.js

It's also possible to control the batch name that shows up in Test Manager. For example:

export APPLITOOLS_BATCH_ID=`uuidgen`
export APPLITOOLS_BATCH_NAME="Login tests"
npm test

Method 2: eyes.setBatch

Provide all Eyes instances with the same value for batch ID. For example:

eyes.setBatch({
  id: SOME_SHARED_VALUE_THAT_WILL_BE_THE_SAME_FOR_ALL_TEST_FILES,
  name: 'My batch'
})

Stitch mode

The default stitch mode is Scroll. In order to change it:

const {Eyes, StitchMode} = require('@applitools/eyes-webdriverio')
 
const eyes = new Eyes()
eyes.setStitchMode(StitchMode.CSS)
 
// to go back to scroll:
eyes.setStitchMode(StitchMode.SCROLL)

Background information

Eyes-WebdriverIO allows you to control if the checkpoint image should include only the viewport - i.e. what you see in the browser window when you first load a page, or if it should also include the full page - i.e. what you would see if you manually scrolled down, or across, a page that is larger than the viewport.

When Eyes-WebdriverIO takes a full page screenshot, it does so by taking multiple screenshots of the viewport at different locations of the page (via the webdriver.io browser driver), and then "stitching" them together. The output is one clear, potentially very large, screenshot of what can be revealed on the page when it is scrolled.

There are two methods for creating the stitched screenshot, and they are both related to the way the page is moved relative to the viewport. Here they are:

1. Stitch mode: Scroll

Using this method, the page is scrolled, just as a user would scroll. Eyes-WebdriverIO takes the viewport screenshot, then scrolls the page to calculated locations. The issue with this method is that the page might respond to scroll events, and change the way it appears visually between the screenshots.

2. Stitch mode: CSS

Using this method, the page is moved around by changing the CSS property transform on the HTML element with different values for translate(x,y). This method is not sensitive to scroll events, and is usually the recommended method for stitching.

Stitch overlap

The stitch overlap is the length of the intersecting area between two screenshots that are stitched together. It's like placing two printed pictures one on top of the other with some overlapping area between them.

This is useful in cases of fixed elements, like a footer, that show up in each of the sub-screenshots. Using a stitch overlap bigger than the size of the footer would make it disappear from every image, and only show up at the bottom of the full page screenshot.

The default stitch overlap is 50 pixels. To change it:

eyes.setStitchOverlap(60)

Match level

The match level determines the way by which Eyes compares the checkpoint image with the baseline image.

The default match level is Strict. To change it:

// Option 1: For the rest of the execution
const {MatchLevel} = require('@applitools/eyes-webdriverio')
eyes.setMatchLevel(MatchLevel.Layout)
 
// Option 2: For a single checkpoint
eyes.check(Target.window().layout())
eyes.check(Target.window().strict())
eyes.check(Target.window().content())
eyes.check(Target.window().exact())

For more information, visit our documentation page: https://applitools.com/docs/common/cmn-eyes-match-levels.html

Ignore displacements

By using ignore displacements you can hide diffs that arise from content whose position on the page has changed, and focus on mismatches caused by actual changes in the content.

The default is false. To change it:

// For the rest of the execution
eyes.setIgnoreDisplacements(true)
 
// For a single checkpoint
eyes.check(Target.window().ignoreDisplacements())

For more information, visit our documentation page: https://applitools.com/docs/topics/test-manager/viewers/tm-diff-displacement.html

Test properties

It's possible to provide additional information about each test in custom fields, which can then show up in Test Manager in their own column.

This is done by calling setProperties on the configuration, and providing it with an array of properties with the structure {name, value}. For example:

const {Eyes, Target} = require('@applitools/eyes-webdriverio')
 
const eyes = new Eyes()
 
const configuration = eyes.getConfiguration()
configuration.setProperties([{name: 'my custom property', value: 'some value'}])
eyes.setConfiguration(configuration)

Test results

The results of the test can be consumed as the return value from eyes.close. Here's an example for creating a formatted output string out of the TestResults object:

function formatTestResults(testResults) {
  return `
Test name                 : ${testResults.getName()}
Test status               : ${testResults.getStatus()}
URL to results            : ${testResults.getUrl()}
Total number of steps     : ${testResults.getSteps()}
Number of matching steps  : ${testResults.getMatches()}
Number of visual diffs    : ${testResults.getMismatches()}
Number of missing steps   : ${testResults.getMissing()}
Display size              : ${testResults.getHostDisplaySize().toString()}
Steps                     :
${testResults
  .getStepsInfo()
  .map(step => {
    return `  ${step.getName()} - ${getStepStatus(step)}`
  })
  .join('\n')}`
}
 
function getStepStatus(step) {
  if (step.getIsDifferent()) {
    return 'Diff'
  } else if (!step.getHasBaselineImage()) {
    return 'New'
  } else if (!step.getHasCurrentImage()) {
    return 'Missing'
  } else {
    return 'Passed'
  }
}

For the full list of methods, visit our documentation page: https://applitools.com/docs/api/eyes-sdk/index-gen/class-testresults-selenium4-javascript.html (This is for our Selenium SDK, but all methods are relevant for Eyes-WebdriverIO as well)

Logging

To enable logging to the console, use the ConsoleLogHandler class:

import {Eyes, ConsoleLogHandler} from '@applitools/eyes-webdriverio'
 
const eyes = new Eyes()
eyes.setLogHandler(new ConsoleLogHandler())
 
// To enable verbose logging:
eyes.setLogHandler(new ConsoleLogHandler(true))

To write logs to file, use the FileLogHandler class. It's possible to configure the file path, verbosity, and whether to append to file.

The API is as follows:

new FileLogHandler(isVerbose, filepath, append)

Default values are:

  • isVerbose: false
  • filepath: 'eyes.log', meaning a file with this name will be created in the current working directory.
  • append: true, meaning that every test will append to the file instead of recreating it.

For example:

const {Eyes, FileLogHandler} = require('@applitools/eyes-webdriverio')
const path = require('path')
 
const eyes = new Eyes()
 
// append non-verbose logs to logs/eyes.log (relative to current working directory)
eyes.setLogHandler(new FileLogHandler(false, path.resolve('logs', 'eyes.log')))
 
// write verbose logs to a new file at logs/eyes-{timestamp}.log (relative to current working directory)
eyes.setLogHandler(new FileLogHandler(true, path.resolve('logs', `eyes-${Date.now()}.log`), false))

Configuring browsers for the Ultrafast grid

When it comes to multiple browsers and mobile devices, the Ultrafast grid shines. It's now possible to run one functional test, and in the background have multiple screenshots rendered for different browsers, viewport sizes, and mobile devices.

The API methods are:

  • configuration.addBrowser(browser) for adding a single browser configuration.
  • configuration.addBrowsers(browser1, browser2, ...) for adding single or multiple browser configurations.

Here are examples for how to execute visual tests on different browsers and platforms:

Desktop browsers
