Selenium with Perl

Your guide to running Selenium Webdriver tests with Perl on BrowserStack.


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

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


Before you can start running your Selenium tests with Perl, ensure the Selenium::Remote::Driver library is installed. Following is the command to install Selenium from command line:

cpanm Selenium::Remote::Driver

Run your first test

To get started, let’s run a simple Selenium Webdriver test. The perl script below opens, inputs a search string, submits the form, asserts the page title and marks the status of test as pass/fail based on the assertion.

Step 1 - Select the OS and device-browser combination

Select the OS and Device-Browser combination you’d like to test on using the drop-down menus below. This will automatically update the Perl code sample below:

Note: Testing on BrowserStack requires username and access key that can be found in account settings.
If you have not created an account yet, you can sign up for a Free Trial or purchase a plan.
Warning: The driver.quit() statement is required, otherwise the test continues to execute, leading to a timeout.

Step 2 - Run the sample test code

Copy the code sample into your code editor, save it as file, and execute the test from your command line.

Command Line
Protip: You can use our capability builder and select from a wide range of custom capabilities that BrowserStack supports.

Step 3 - Verify the results

Once the test has run successfully, it is time to verify the results. The Selenium Webdriver test should have opened a URL, inputted a string, submitted the form, returned the page title and marked the test based on the title.

Note: Your results will be displayed on the command-line interface and on the Automate dashboard, where you can see Text Logs, Screenshots of every Selenium command, and a Video Recording of your entire test. (Read more about viewing test results and debugging failed tests)

Mark tests as passed or failed

BrowserStack does not know whether your test’s assertions have passed or failed because only the test script knows whether the assertions have passed. Therefore, based on the assertions on your script, you have to explicitly inform BrowserStack whether your tests have passed or not and this document will help you in doing that exactly.

It is possible to mark tests as either a pass or a fail and also give a reason for the same, using the following snippet (Refer the above sample script which implements the snippet shown below):

# for marking the test as passed
$driver->execute_script('browserstack_executor: {"action": "setSessionStatus", "arguments": {"status":"passed", "reason": "Yaay! My test has passed"}}');

#for marking the test as failed
$driver->execute_script('browserstack_executor: {"action": "setSessionStatus", "arguments": {"status":"failed", "reason": "Oops! My test has failed"}}');
Note: The arguments passed in the JavaScript method for setting the status and the corresponding reason for the test are status and reason.
  • status accepts either passed or failed as the value
  • reason accepts a value in string datatype

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.

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 Perl script. 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:

$extraCaps->{"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 capability to false.

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