Selenium with Protractor

A guide to run Selenium Webdriver tests with Protractor on BrowserStack.

Important: Protractor is no longer supported by the Angular team. If you’re looking for alternatives, take a look at some popular frameworks and their migration guides:

Introduction

BrowserStack gives you instant access to our Selenium Grid of 3000+ real devices and desktop browsers. Running your Selenium tests with Protractor on BrowserStack is simple. This guide will help you:

  1. Run your first test
  2. Integrate your tests with BrowserStack
  3. Mark tests as passed or failed
  4. Debug your app

Prerequisites

Run your first test

Protip: Selenium 4 is now supported on BrowserStack. To use the Selenium 4 client bindings, modify your existing test scripts as follows:
  • Edit or add capabilities in the W3C format using our W3C capability generator.
  • Add the seleniumVersion capability in your test script and set the value to 4.0.0.

To run your first Protractor test on BrowserStack, follow the steps below:

Step 1: Clone the protractor-browserstack sample repo on GitHub using:

   git clone https://github.com/browserstack/protractor-browserstack.git
   cd protractor-browserstack

Step 2: Install the required dependencies by running the following command in your command line:

    npm install

Step 3: Setup your credentials in the protractor-browserstack/conf/parallel.conf.js file as shown below:

parallel.conf.js
    exports.config = {
     ...
      'browserstackUser': process.env.BROWSERSTACK_USERNAME || 'BROWSERSTACK_USERNAME',
      'browserstackKey': process.env.BROWSERSTACK_ACCESS_KEY || 'BROWSERSTACK_ACCESS_KEY',
     ...
    }

Alternatively, you can set the environment variables in your system as shown below:

# Set these values in your ~/.zprofile (zsh) or ~/.profile (bash)
  export BROWSERSTACK_USERNAME="YOUR_USERNAME"
  export BROWSERSTACK_ACCESS_KEY="YOUR_ACCESS_KEY"
# setx.exe does not set the environment variable in the current command prompt, but it will be available in subsequent command prompts
  setx BROWSERSTACK_USERNAME="YOUR_USERNAME"
  setx BROWSERSTACK_ACCESS_KEY="YOUR_ACCESS_KEY"

# Verify whether the variables have been set
echo BROWSERSTACK_USERNAME
echo BROWSERSTACK_ACCESS_KEY

Step 4: Run your first test using the following command:

   npm run parallel

You can visit BrowserStack Automate Dashboard and see your test there once it has successfully completed.

Details of your first test

The specs for the test that you just ran can be found in protractor-browserstack/specs/single.js. The test case below searches for the string “BrowserStack” on Google, and checks if the title of the resulting page is “BrowserStack - Google Search”:

describe('Google\'s Search Functionality', function() {
  it('can find search results', function() {
    browser.driver.get('https://google.com/ncr').then(function() {
      browser.driver.findElement(by.name('q')).sendKeys('BrowserStack\n').then(function() {
        expect(browser.driver.getTitle()).toEqual('BrowserStack - Google Search');
      });
    });
  });
});

Integrate your tests with BrowserStack

In the sample repository, you can find conf/parallel.conf.js file which is responsible for configuring your test to run on BrowserStack. The useful sections of the file are shown below which enable the tests to run on BrowserStack:

exports.config = {
  'specs': [ '../specs/single.js' ],
  'browserstackUser': process.env.BROWSERSTACK_USERNAME || 'BROWSERSTACK_USERNAME',
  'browserstackKey': process.env.BROWSERSTACK_ACCESS_KEY || 'BROWSERSTACK_ACCESS_KEY',

  'commonCapabilities': {
    'build': 'browserstack-build-1',
    'name': 'parallel_test',
    'browserstack.debug': 'true',
    'browserName': 'Chrome'
  },

  'multiCapabilities': [{
    'browserName': 'Chrome'
  },{
    'browserName': 'Safari'
  },{
    'browserName': 'Firefox'
  },{
    'browserName': 'IE'
  }],

  // Code to mark the status of test on BrowserStack based on test assertions
  onComplete: function (passed) {
    if (!passed) {
      browser.executeScript('browserstack_executor: {"action": "setSessionStatus", "arguments": {"status":"failed","reason": "At least 1 assertion has failed"}}');
    }
    if (passed) {
      browser.executeScript('browserstack_executor: {"action": "setSessionStatus", "arguments": {"status":"passed","reason": "All assertions passed"}}');
    }
  }
};

// Code to support common capabilities
exports.config.multiCapabilities.forEach(function(caps){
  for(var i in exports.config.commonCapabilities) caps[i] = caps[i] || exports.config.commonCapabilities[i];
});

Mark tests as passed or failed

BrowserStack does not know whether your test’s assertions have passed or failed because only the framework knows whether the assertions have passed.

In the parallel.conf.js file that is used to run your Protractor tests, the following snippet is used to mark tests as passed or failed depending on the assertion status of your tests:

onComplete: function (passed) {
  if (!passed) {
    browser.executeScript('browserstack_executor: {"action": "setSessionStatus", "arguments": {"status":"failed","reason": "At least 1 assertion has failed"}}');
  }
  if (passed) {
    browser.executeScript('browserstack_executor: {"action": "setSessionStatus", "arguments": {"status":"passed","reason": "All assertions passed"}}');
  }
}

The above onComplete function is invoked after every Protractor test that is executed. Based on the status of the assertions, a javascript executor is fired which marks the status of your test on BrowserStack.

Marking test as pass/fail is also possible using our REST API at any point in the test or also after the test has concluded. You can read more about marking test using REST API and use it if it fits your use case.

Debug your app

BrowserStack provides a range of debugging tools to help you quickly identify and fix bugs you discover through your automated tests. Learn more about how to debug tests on BrowserStack using the Automate Dashboard.

Text logs

Text Logs are a comprehensive record of your test. They are used to identify all the steps executed in the test and troubleshoot errors for the failed step. Text Logs are accessible from the Automate dashboard or via our REST API.

Visual logs

Visual Logs automatically capture the screenshots generated at every Selenium command run through your Protractor tests. Visual logs help with debugging the exact step and the page where failure occurred. They also help identify any layout or design related issues with your web pages on different browsers.

Visual Logs are disabled by default. In order to enable Visual Logs you will need to set browserstack.debug capability to true.

'capabilities': {
  'browserstack.debug': 'true'
}

Video recording

Every test run on the BrowserStack Selenium grid is recorded exactly as it is executed on our remote machine. This feature is particularly helpful whenever a browser test fails. You can access videos from Automate Dashboard for each session. You can also download the videos from the Dashboard or retrieve a link to download the video using our REST API.

Note: Video recording increases test execution time slightly. You can disable this feature by setting the browserstack.video capability to false.

Console logs

Console Logs capture the browser’s console output at various steps of the test to troubleshoot javascript issues. You can retrieve Console Logs using an URL that you can get from our REST API. You will also be able to download logs from Automate Dashboard.

Console Logs are enabled with log level set to ‘errors’ by default. To set different log levels, you need to use the capability browserstack.console with values disable, errors, warnings, info or verbose, as shown below:

'capabilities': {
  'browserstack.console': 'errors' // You can choose the log-level here
}

Network logs

Network Logs capture the browser’s performance data such as network traffic, latency, HTTP requests and responses in the HAR format. You can download network logs using a link that you can get from our REST API or from the Automate Dashboard. You can visualize HAR files using the HAR Viewer.

Network Logs are disabled by default. To enable Network Logs use the capability browserstack.networkLogs with the value true, as shown below:

'capabilities': {
  'browserstack.networkLogs': 'true'
}

In addition to these logs BrowserStack also provides Raw logs, Selenium logs, Appium logs and Interactive session. You can find the complete details to enable all the debugging options.
