Waiting for Browser API Calls | Bondar Academy

Lesson Summary

In this lesson, we explore how to dynamically wait for browser API responses and its significance in ensuring test stability. The focus is on automating a scenario where the text "Ponder Academy" must be located on a webpage. Key Concepts Flakiness in Tests: Initial tests may fail due to timing issues, especially when elements are not yet loaded. Assertions: Using should assertions allows Cypress to retry until the expected condition is met. Steps to Implement Dynamic Waiting Identify the locator for the articles, e.g., AppArticlesList . Log into the application and set up the test. Use cy.intercept to declare an interception for the API call without mocking the response. Assign an alias to the intercepted request, e.g., articleAPIcall . Before invoking the text extraction, use cy.wait with the alias to ensure the API response is received. Benefits of Dynamic Waiting This technique allows tests to be more stable by ensuring that data is fully loaded before assertions are made. It also enables access to the API request and response details, which can be used for further validations. Example Validation After waiting for the API response, you can validate specific properties from the response object: expect(apiArticleObject.response.body.articles[0].title).to.contain('Ponder Academy'); In summary, dynamically waiting for API responses is essential for creating reliable tests in applications with asynchronous data loading. This method enhances test accuracy and stability.
