Test Hooks | Bondar Academy

Lesson Summary

In this lesson, we explore test hooks such as BeforeAll , BeforeEach , AfterAll , and AfterEach . These hooks are essential for organizing code, reducing duplication, and improving the structure of test cases. Key Concepts BeforeEach Hook: Executes code before each test, helping to eliminate repetitive code. BeforeAll Hook: Runs once before all tests in a suite, useful for setting up general preconditions. AfterEach Hook: Executes code after each test, but should be used cautiously to avoid test flakiness. AfterAll Hook: Runs after all tests, often used for cleanup tasks. Usage Example To navigate to a specific page, you might initially write repetitive code in multiple tests. By using the BeforeEach hook, you can centralize this navigation code: beforeEach(() => { // Navigation code here }); Best Practices Avoid using AfterEach and AfterAll unless necessary; prefer BeforeEach for setup tasks. Group tests using describe to apply different BeforeEach hooks to specific test suites. Use test.describe.skip or test.describe.only to manage test execution effectively. In summary, Playwright provides four hooks to optimize your testing strategy, allowing for better organization and execution of tests.
