@percy/webdriverio

Version Test

Percy visual testing for WebdriverIO.

Installation

$ npm install --save-dev @percy/cli @percy/webdriverio

Usage

This is an example using the percySnapshot() function in async mode.

const percySnapshot = require('@percy/webdriverio');

describe('webdriver.io page', () => {
  it('should have the right title', async () => {
    await browser.url('https://webdriver.io');
    await expect(browser).toHaveTitle('WebdriverIO · Next-gen browser and mobile automation test framework for Node.js');
    await percySnapshot('webdriver.io page');
  });
});

Running the test above will result in the following log:

$ wdio wdio.conf.js
...

[...] webdriver.io page
[percy] Percy is not running, disabling snapshots
[...]    ✓ should have the right title

...

When running with percy exec, and your project's PERCY_TOKEN, a new Percy build will be created and snapshots will be uploaded to your project.

$ export PERCY_TOKEN=[your-project-token]
$ percy exec -- wdio wdio.conf.js
[percy] Percy has started!
[percy] Created build #1: https://percy.io/[your-project]
[percy] Running "wdio wdio.conf.js"
...

[...] webdriver.io page
[percy] Snapshot taken "webdriver.io page"
[...]    ✓ should have the right title

...
[percy] Stopping percy...
[percy] Finalized build #1: https://percy.io/[your-project]
[percy] Done!

Standalone mode

When using WebdriverIO in standalone mode, the browser object must be provided as the first argument to the percySnapshot function.

const { remote } = require('webdriverio');
const percySnapshot = require('@percy/webdriverio');

(async () => {
  const browser = await remote({
    logLevel: 'trace',
    capabilities: {
      browserName: 'chrome'
    }
  });

  await browser.url('https://duckduckgo.com');

  const inputElem = await browser.$('#search_form_input_homepage');
  await inputElem.setValue('WebdriverIO');

  const submitBtn = await browser.$('#search_button_homepage');
  await submitBtn.click();

  // the browser object is required in standalone mode
  percySnapshot(browser, 'WebdriverIO at DuckDuckGo');

  await browser.deleteSession();
})().catch((e) => console.error(e));

Configuration

percySnapshot(name[, options])

percySnapshot(browser, name[, options]) (standalone mode only)

Upgrading

Automatically with @percy/migrate

We built a tool to help automate migrating to the new CLI toolchain! Migrating can be done by running the following commands and following the prompts:

$ npx @percy/migrate
? Are you currently using @percy/webdriverio? Yes
? Install @percy/cli (required to run percy)? Yes
? Migrate Percy config file? Yes
? Upgrade SDK to @percy/webdriverio@2.0.0? Yes

This will automatically run the changes described below for you.

Manually

If you're coming from a pre-2.0 version of this package, the percySnapshot function is now the default export, and the browser argument is now only required when used in standalone mode.

// before 
const { percySnapshot } = require('@percy/webdriverio');
await percySnapshot(browser, 'Snapshot name', options);

// after
const percySnapshot = require('@percy/webdriverio');
await percySnapshot('Snapshot name', options);

// in standalone mode, browser is still required
await percySnapshot(browser, 'Snapshot name', options);

Migrating Config

If you have a previous Percy configuration file, migrate it to the newest version with the config:migrate command:

$ percy config:migrate
