webautomator

Web automation using rendered web context

Installation

webautomator may be installed via npm with

npm install webautomator

You will need to also install and set-up selenium-webdriver.

Usage

The demo below is included in the example directory. You may also find the tests to be helpful.

const {Builder} = require('selenium-webdriver');
const {WebAutomator} = require('webautomator');
require('chromedriver');
 
(async function demo() {
  const driver = new Builder().forBrowser('chrome').build();
  const automator = new WebAutomator(driver);
  try {
    await driver.navigate().to(`${__dirname}/demo.html`);
    await automator.set('First Name').to('Joyce');
    await automator.set('Last Name').to('Byers');
    await automator.set('Gender').to('Female');
    await automator.after('Child Information', async context => {
      await context.set('First Name').to('Will');
      await context.set('Last Name').to('Byers');
      await context.set('Gender').to('Male');
      await context.set('Date of Birth').to('3/22/1971');
    });
    await automator.set('Shipping Information').to('2-Day');
    await automator.click('I confirm that these details are accurate.');
  } finally {
    await driver.quit();
  }
})();

Documentation

Getting Started

To get started you need to create a WebDriver instance for WebAutomator to use. See Using the Builder API - selenium-webdriver - npm for details.

With a WebDriver instance ready you can no instantiate an instance of the WebAutomator class which will use the underlying WebDriver instance for all of its browser calls:

const {Builder} = require('selenium-webdriver');
const {WebAutomator} = require("webautomator");
 
const webDriver = new Builder().forBrowser('chrome').build();
const webAutomator = new WebAutomator(webDriver);

API

Elements are located by preceding text, by placeholder attributes (input and textarea elements), and by title attributes.

get

Get properties such as widget values and options from elements on the page.

Examples:

1. Get the options for a select element preceded by the text "Gender":

   const genderOptions = await webAutomator.get("Gender").options();

2. Get the value of a text input element which is either preceded by the text "First Name" or has a placeholder attribute value of "First Name":

   const firstName = await webAutomator.get("First Name").value();

3. Get the values for a compound date element which consists of a month select element, a day number input, and a year number input:

   const {month, day, year} = await webAutomator.get("Date of Birth").values("month", "day", "year");

   Note that in this case, the property names month, day, and year are arbitrary. They could be named a, b, c if you wanted them to be named such. The ...names in values(...names) is simply a list of names to assign each value to.

set

Sets form widget values (input, textarea, select).

Examples:

1. Set the value of a text input preceded by the text "Last Name" to "Byers":

   await webAutomator.set("Last Name").to("Byers");

2. Set the values in a compound date element which consists of a month select element, a day number input, and a year number input:

   await webAutomator.set("Date of Birth").to("March", "22", "1971");

click

Clicks elements on the page.

Examples:

1. Click a "Submit" button:

   await webAutomator.click("Submit");

2. Click a label associated with a radio input to toggle its checked attribute:

   await webAutomator.click("I confirm that these details are accurate.");

can.spy

Determines if some text is displayed on the page.

Example:

if (await webAutomator.can.spy("Alert")) {
  // do something
}

can.not.spy

Determines if some text is not displayed on the page.

if (await webAutomator.can.not.spy("You've reached your maximum number of items in you're cart!")) {
  // do something
}

after

Allows narrowing the scope of the searched context on the page to be explicitly after some text.

Example:

await webAutomator.after("Child Information", async function (webContext) {
  await webContext.set("First Name").to("Will");
});

before

Allows narrowing the scope of the searched context on the page to be explicitly before some text.

Example:

await webAutomator.before("Child Information", async function (webContext) {
  await webContext.set("First Name").to("Joyce");
});

between

Allows narrowing the scope of the searched context on the page to be explicitly between some texts.

Example:

await webAutomator.between("Parent Information").and("Child Information", async function (webContext) {
  await webContext.set("First Name").to("Joyce");
});

getContent (Experimental)

Gets an XML representation using markup derived from WAI-ARIA roles.

May be used in snapshot testing.

Example:

expect(await webAutomator.getContent()).toMatchSnapshot();
