@percy/protractor

Installation

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

Usage

This is an example using the percySnapshot() function using async/await.

import percySnapshot from '@percy/protractor';

describe('angularjs homepage', function() {
  it('should greet the named user', async function() {
    await browser.get('http://www.angularjs.org');
    await percySnapshot('AngularJS homepage');

    await element(by.model('yourName')).sendKeys('Percy');
    var greeting = element(by.binding('yourName'));
    expect(await greeting.getText()).toEqual('Hello Percy!');

    await percySnapshot('AngularJS homepage greeting');
  });
});

Running the test above will result in the following log:

$ protractor conf.js
...

[percy] Percy is not running, disabling snapshots
  ✓ angularjs homepage should greet the named user

  1 passing (1s)

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 -- protractor conf.js
[percy] Percy has started!
[percy] Created build #1: https://percy.io/[your-project]
[percy] Running "protractor conf.js"
...

[percy] Snapshot taken "AngularJS homepage"
[percy] Snapshot taken "AngularJS homepage greeting"
  ✓ angularjs homepage should greet the named user

  1 passing (1s)

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

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/protractor? Yes
? Install @percy/cli (required to run percy)? Yes
? Migrate Percy config file? Yes
? Upgrade SDK to @percy/protractor@2.0.0? Yes

This will automatically run the changes described below for you.

Manually

Import change

If you're coming from a pre-2.0 version of this package, the percySnapshot function is now the default export.

// before
const { percySnapshot } = require('@percy/protractor');

// after
const percySnapshot = require('@percy/protractor');

Migrating Config

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

$ percy config:migrate

Usage no npm install needed!
