Running Selenium Tests on Sauce Labs

Writing Selenium Test Scripts for Sauce Labs Execution

• Create a WebDriver instance using the desired properties and the Sauce Labs URL.
• Go to the desired URL or perform the necessary installation steps.
• You can interact with page elements using Selenium WebDriver commands such as searching for elements, clicking buttons, typing text, etc.
• Add assertions to ensure the expected results.
• Handle any exceptions that may occur during test execution.
• Clean up or complete any necessary actions. End the WebDriver session.

Configuring Desired Capabilities for Sauce Labs Testing

When you define the features you want Sauce Labs to test, you can configure various settings to specify the browser, operating system, version, resolution, timeouts, and other parameters.

Parallel Test Execution on Sauce Labs

Understanding the concept of parallel test execution

Concurrent testing is the concurrent, simultaneous, or parallel running of multiple tests. Instead of executing tests sequentially, parallel execution allows tests to be distributed across multiple threads, processes, or machines, enabling faster testing and more efficient use of resources.

It is important to ensure that your tests are safe and independent to avoid conflicts and ensure reliable results during parallel execution. Tests should not depend on shared resources.

Configuring parallel testing with Sauce Labs

1. Create a Sauce Labs account and obtain your username and password if you have not already done so.
2. Choose a test execution framework that supports parallel testing, such as TestNG, JUnit, Pytest, or any other framework of your choice.
3. Each test framework has its configuration mechanism for parallel execution. Configure the framework to run tests in parallel by specifying the number of threads.
4. Set the desired properties to specify the browser, operating system, and other parameters for each test session. You can dynamically set these properties according to your test requirements.
5. Ensure that each test script creates its instance of WebDriver and uses the desired functions configured for parallel execution.
6. Your test execution framework distributes tests across parallel threads or processes. This can be done by setting the parallel execution options in the test framework configuration file or by using annotations in the test scripts.
7. Run the test configuration using the specified parallel settings. The test execution framework splits tests across multiple threads or processes and runs them concurrently in Sauce Labs.
8. Track test progress and results during parallel testing. Sauce Labs provides a dashboard where you can track test execution status, view logs, and view screenshots and videos of testing.

Sauce Labs Test Configuration and Customization

Configuring Test Timeouts, Screen Resolution, and Other Settings

Test timeouts:

You can configure test times by setting the desired timeout attribute in your test scripts or test framework configuration. The timeout property specifies the maximum time in milliseconds the test should wait for the command to complete.

Screen resolution:

You can set the screenResolution for your tests by specifying the desired screen resolution. The screenResolution property allows you to set the desired width and height of the browser window during testing. Specify the screen resolution as a width X height.

Other settings:

Some commonly used attributes are browser name (specifies the browser to use), version (specifies the browser version), platform (specifies the operating system), name (specifies the name of the test), and tags (specifies the tags to classify the test ).

Customizing test environment and capabilities

Replace USERNAME and ACCESS_KEY with your Sauce Labs username and access key respectively.

Handling Test Data and Environment Variables

Test data management:

Keep test data separate from your test scripts for easy and flexible maintenance. You can save test data to files (such as CSV, JSON, or Excel) or databases. Implement data-driven testing techniques where test scripts read test data from external sources at runtime.

Environmental variables:

Store configuration values, sensitive data, or dynamic values as environment variables. Test scripts access these variables at runtime, allowing easy configuration in different environments.

Configuration files:

Create configuration files that contain environment-specific settings, credentials, or other configuration information. Your test programs can read these files to configure the test environment. Save separate configuration files for different environments such as development, staging, and production.
