API testing in Playwright involves interacting with web applications at the API level to validate functionality, reliability, efficiency, and security of RESTful services and endpoints.
API tests are faster, more reliable, and offer better coverage than UI tests alone, forming a crucial part of robust test automation.
Implementing API tests in Playwright includes extending the auth.setup.ts file for API authentication with an ACCESS_TOKEN environment variable.
Creating test data for invalid credentials enables thorough testing of authentication, authorization, and data encryption in APIs.
Negative test cases in 'authentication.spec.ts' validate how APIs handle invalid data inputs, ensuring robust error handling and system stability.
The 'article.spec.ts' file focuses on validating CRUD functionality, ensuring efficient management of data operations throughout the system.
Implementing a tear-down process post-testing is crucial for cleaning up the environment and maintaining test isolation, preventing flaky tests.
Next steps include implementing CI/CD integration to automate the test execution pipeline in the Playwright framework.
Initiating discussions on this topic is encouraged to drive further refinement and enhancements in testing capabilities.
Building a robust framework in Playwright involves API testing, creating test data, validating CRUD operations, and implementing proper tear-down processes.
