Best Automation Practices  for an SDET to Keep in Mind

Before patting yourself on the back for a job well done, it's crucial to consider some factors if you want to excel in automation as an SDET.

Adopting best practices is imperative for creating maintainable, scalable, and effective automated tests as an automation engineer.

Here are some key best practices to keep in mind:

Follow the Page Object Model (POM)

  • Why: Enhances maintainability by separating page-specific actions and elements from test logic.
  • How: Create a class for each page, encapsulating its elements and actions, and use these objects in your tests.

Use Descriptive and Meaningful Names:

  • Why: Improves code readability and maintenance.
  • How: Choose names that clearly convey the purpose of variables, methods, and classes. Avoid vague or overly generic names.

Prioritize Test Independence:

  • Why: Isolates tests to ensure that the failure of one test does not affect others.
  • How: Avoid dependencies between tests. Each test should set up its required environment.

Implement Explicit Waits:

  • Why: Enhances test stability by allowing the automation script to wait for elements to be in the desired state.
  • How: Use explicit waits to wait for specific conditions before performing actions.

Parameterize Tests for Reusability:

  • Why: Enables the same test logic to be reused with different input values.
  • How: Use parameters to make tests versatile. This is especially useful for data-driven testing.

Keep Tests Short and Focused:

  • Why: Improves maintainability and ease of debugging.
  • How: Each test should focus on a specific scenario, making it easier to pinpoint issues when they arise.

Implement Proper Logging:

  • Why: Facilitates debugging and troubleshooting.
  • How: Use logging frameworks to capture relevant information during test execution.

Handle Exceptions Gracefully:

  • Why: Prevents abrupt test failures and provides more context in case of issues.
  • How: Implement try-catch blocks to handle exceptions and log informative error messages.

Version Control for Test Code:

  • Why: Facilitates collaboration and provides a version history for your automation code.
  • How: Use version control systems like Git to manage and track changes to your codebase.

Continuous Integration:

  • Why: Ensures automated tests are integrated and run with every code change.
  • How: Integrate your tests into a CI/CD pipeline to catch issues early and provide quick feedback.

Regularly Review and Refactor Code:

  • Why: Prevents the accumulation of technical debt and ensures code remains efficient.
  • How: Regularly review and refactor your codebase to maintain readability and efficiency.

Cross-Browser and Cross-Platform Testing:

  • Why: Ensures application compatibility across different browsers and platforms.
  • How: Include tests for various browsers and platforms to validate a consistent user experience.

Parallel Execution:

  • Why: Reduces test execution time, improving efficiency.
  • How: Use parallel execution to run tests concurrently, taking advantage of available resources.

Regularly Update Dependencies:

  • Why: Ensures that your automation tools and libraries are up-to-date.
  • How: Regularly check for updates to tools and dependencies and update as needed.

Documentation:

  • Why: Facilitates understanding and collaboration.
  • How: Document your code, including the purpose of tests, any workarounds, and any assumptions made.
