Automation testing requires interacting with different UI elements in an application. Tests may fail for several reasons such as incorrect selectors, synchronization issues, or unexpected changes in the UI. Identifying reliable UI selectors is therefore crucial when writing complex automation scripts. One of the most common causes of UI automation failures is the use of incorrect or unstable selectors.
Some common reasons why automation scripts fail include:
Targeting Incorrect Selectors
- The UI element no longer exists on the page.
- The selector matches multiple UI elements.
- The UI structure has changed after application updates.
Timing and Synchronization Issues
- Modern web applications often load content asynchronously. As a result, UI elements may appear after a delay. Tests can fail if the script attempts to interact with an element before it is available. Using proper waiting mechanisms such as explicit waits and assertions helps ensure that elements are present and in the correct state before interacting with them.
Playwright Inspector
Debugging tools such as the Playwright Inspector allow to pause test execution and visually inspect the web page during test runs. This makes it easier to identify locator issues and understand how the test interacts with the application.
The Playwright Inspector works as a debugging interface that opens when Playwright tests are executed in debug mode. It provides several useful capabilities:
- Pause and step through test execution
- Inspect elements on the page
- Validate selectors used in the test
- Generate reliable locators
- Observe browser actions in real time
Because Playwright interacts with a real browser, it allows to observe actual browser behavior. This helps in verifying that the application performs as expected during automation. With the Inspector, you can:
- Watch the browser perform each action
- Verify navigation, clicks, and form submissions
- Confirm that the application behaves as expected
- Step through the test line by line
- Ensure waits and assertions are placed correctly
In previous blog we have already explored how Playwright can be used for Dynamics 365 automation testing wherein we have simply created contact record using Typescript code... Read More
