Migrating from BrowserStack to LambdaTest


LambdaTest and BrowserStack both offer the cloud-based Selenium Grid. Hence, you can easily migrate your existing Selenium test automation scripts (or suites) from BrowserStack to LambdaTest

[Note: This guide covers the migration of tests running on the cloud grid that uses Selenium 3.141.59]

Introduction#

Migrating your existing tests running on BrowserStack to LambdaTest can be done with just a few lines of change. In this guide, we will see how you can use LambdaTest desired capabilities in your tests, authenticate your test session, and run tests on the browsers in our cloud.

Changes to be made in your scripts#

Authentication#

Firstly, you need to change the authentication in your configuration settings of your test suite. For running tests on LambdaTest Selenium Grid, you need to have a valid user_name and access_key to perform tests on our Grid. In case you do not have an account on LambdaTest, visit the LambdaTest signup page and create a new account.

The following are the changes in the parameters:

  • Username
  • Access Key

You can find Username and Access Key in the LambdaTest Profile Section of the Automation Dashboard.

When migrating from BrowserStack to LambdaTest, you need to make the following changes in the existing code:

  • UserName
  • AccessKey
  • Hub URL
  • Desired Capabilities

Here is a side-by-side comparison of each of the fields that we have highlighted above:

PropertyBrowserStackLambdaTest
UserName (Type: String)UserName to access Selenium Grid on BrowserStackUserName to access Selenium Grid on LambdaTest
AccessKey (Type: String)AccessKey to access Selenium Grid on BrowserStackAccessKey to access Selenium Grid on LambdaTest
Selenium Hub URL (Type: String)@hub-cloud.browserstack.com/wd/hub@hub.lambdatest.com/wd/hub

For a Java-based implementation, here are the changes in the script as far as the authentication stage is concerned:

BrowserStack

// test.javapublic static final String user_name = "BrowserStack_UserName";public static final String access_key = "BrowserStack_AccessKey";

LambdaTest

// test.javapublic static final String user_name = "LambdaTest_UserName";public static final String access_key = "LambdaTest_AccessKey";

Changes in Hub URL#

You need to now change the hub URL in the configuration settings of your test suite. Hub URL is of type String and it defines the Hub location to which the Selenium tests would be submitted for execution.

Here is a side-by-side comparison of the Hub URL for BrowserStack and LambdaTest:

PropertyBrowserStackLambdaTest
Selenium Hub URL (Type: String)@hub-cloud.browserstack.com/wd/hub@hub.lambdatest.com/wd/hub

For a Java-based implementation, here are the changes in the script as far as the Hub URL is concerned:

BrowserStack

// test.javapublic static final String Hub_URL = "https://" + user_name + ":" + access_key + "@hub-cloud.browserstack.com/wd/hub";

LambdaTest

// test.javapublic static final String Hub_URL = "https://" + user_name + ":" + access_key + "@hub.lambdatest.com/wd/hub";

Capabilities Generator#

Capabilities generator let you configure the desired capabilities (or capabilities) which are configuration options that let you set the following:

  • Desired browser
  • Desired browser version
  • Desired platform (or operating system)

Optionally, you can also choose the Selenium version and other advanced options present in the Selenium Capabilities Generator. For this migration guide, we have only restricted to the three capabilities listed above.

For the migration, we have considered Java-based Selenium automation tests. Shown below are the screenshots of capabilities generator of BrowserStack and LambdaTest:

LambdaTest

You can generate the corresponding Selenium capabilities using the LambdaTest capabilities generator. Capabilities matching the ones shown in the BrowserStack capabilities screenshot is below:

Shown below is the comparison of the capabilities generated by BrowserStack and LambdaTest capabilities generator:

CapabilitiesBrowserStackLambdaTest
BrowserbrowserbrowserName
Browser Versionbrowser_versionversion
Platform Nameosplatform
Platform Versionos_versionN.A

The platform (or OS) version is a part of the platform name in LambdaTest. Hence, it is mentioned as NA (Not Applicable) in the Capabilities Comparison Table.

Here is the summary of the comparison of Desired Capabilities for Java language:

BrowserStack

// test.javaDesiredCapabilities caps = new DesiredCapabilities();caps.setCapability("os", "Windows");caps.setCapability("os_version", "10");caps.setCapability("browser", "Chrome");caps.setCapability("browser_version", "latest");caps.setCapability("browserstack.local", "false");caps.setCapability("browserstack.selenium_version", "3.141.59");

LambdaTest

// test.javaDesiredCapabilities capabilities = new DesiredCapabilities();capabilities.setCapability("build", "your build name");capabilities.setCapability("name", "your test name");capabilities.setCapability("platform", "Windows 10");capabilities.setCapability("browserName", "Chrome");capabilities.setCapability("version","92.0");

Hands On Guide - BrowserStack To LambdaTest Migration#

Let’s take a practical example that demonstrates the entire migration process. The test scenario is to open Google on Chrome (version 92.0) that is installed on a Windows 10 machine.

BrowserStack#

// test.javaimport org.openqa.selenium.By;import org.openqa.selenium.Platform;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;import org.openqa.selenium.remote.DesiredCapabilities;import org.openqa.selenium.remote.RemoteWebDriver;import java.net.URL; public class BrowserStackSampleTest{    public static final String user_name = "BrowserStack_user_name";    public static final String access_key = "BrowserStack_access_key";    public static final String grid_url = "https://" + user_name + ":" + access_key + "@hub-cloud.browserstack.com/wd/hub";    public static void main(String[] args) throws Exception    {        DesiredCapabilities caps = new DesiredCapabilities();         caps.setCapability("build", "Build #1");        caps.setCapability("name", "Sample project");        caps.setCapability("os", "Windows");        caps.setCapability("os_version", "10");        caps.setCapability("browser", "Chrome");        caps.setCapability("browser_version", "92.0");                WebDriver driver = new RemoteWebDriver(new URL(grid_url), caps);        driver.get("http://www.google.com");         driver.quit();    }}

LambdaTest#

// test.javaimport org.openqa.selenium.By;import org.openqa.selenium.Platform;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;import org.openqa.selenium.remote.DesiredCapabilities;import org.openqa.selenium.remote.RemoteWebDriver;import java.net.URL; public class LambdaTestSampleTest{    public static final String user_name = "LambdaTest_user_name";    public static final String access_key = "LambdaTest_access_key";    public static final String grid_url = "https://" + user_name + ":" + access_key + "@hub.lambdatest.com/wd/hub";    public static void main(String[] args) throws Exception    {        DesiredCapabilities caps = new DesiredCapabilities();         capabilities.setCapability("build", "Build #1");        capabilities.setCapability("name","Sample project");        capabilities.setCapability("platform", "Windows 10 ");        capabilities.setCapability("browserName", "Chrome");        capabilities.setCapability("version", "92.0");         WebDriver driver = new RemoteWebDriver(new URL(grid_url), caps);        driver.get("http://www.google.com");         driver.quit();    }}

As seen above, the majority of the implementation is unchanged. Changes are only made on the infrastructure side (i.e. instead of BrowserStack, the tests would be run on LambdaTest).

Here is a side-by-side comparison of what has changed from the implementation point of view:

BrowserStack

// test.java
public static final String user_name = "BrowserStack_user_name";public static final String access_key = "BrowserStack_access_key";public static final String grid_url = "https://" + user_name + ":" + access_key + "@hub-cloud.browserstack.com/wd/hub";public static void main(String[] args) throws Exception{    DesiredCapabilities caps = new DesiredCapabilities();
    caps.setCapability("build", "Build #1");    caps.setCapability("name", "Sample project");    caps.setCapability("os", "Windows");    caps.setCapability("os_version", "10");    caps.setCapability("browser", "Chrome");    caps.setCapability("browser_version", "92.0");

LambdaTest

// test.javapublic static final String user_name = "LambdaTest_user_name";public static final String access_key = "LambdaTest_access_key";public static final String grid_url = "https://" + user_name + ":" + access_key + "@hub.lambdatest.com/wd/hub";public static void main(String[] args) throws Exception{    DesiredCapabilities caps = new DesiredCapabilities();
    capabilities.setCapability("build", "Build #1");    capabilities.setCapability("name","Sample project");    capabilities.setCapability("platform", "Windows 10 ");    capabilities.setCapability("browserName", "Chrome");    capabilities.setCapability("version", "92.0");
