BiDi is a browser extension that helps developers to debug and test web applications. It provides a variety of features, including the ability to capture JavaScript errors in the browser console.

To use BiDi to capture JavaScript errors, you first need to install the BiDi extension for your browser. BiDi is available for Chrome, Firefox, and Edge. Once you have installed the extension, you need to enable the “Capture JavaScript errors” option in the BiDi extension options.

Once you have enabled the “Capture JavaScript errors” option, you can navigate to the web page that you want to test and reproduce the error that you want to capture. When the error occurs, open the browser console and click on the “BiDi” tab. Then, click on the “Capture errors” button.

BiDi will then capture all of the JavaScript errors that occurred on the page and display them in the BiDi tab. You can then view the errors and their details, and save them to a file for later analysis.

By using BiDi to capture JavaScript errors, you can identify and fix bugs in your web applications more quickly and efficiently. This can lead to a reduction in the number of bugs that users experience, and an improved overall user experience.

Whether WebDriver with BiDi is better than Cypress/Playwright depends on your specific needs and preferences.

Yes, you can use many of the same waiting strategies in BiDi WebDriver that you can use in Selenium WebDriver. For example, you can use the following waiting strategies:

  • Explicit wait: An explicit wait is a type of wait that waits for a specific condition to be met before proceeding. For example, you could use an explicit wait to wait for a web element to be visible before interacting with it.

  • Implicit wait: An implicit wait is a type of wait that waits for a specific amount of time before proceeding. For example, you could use an implicit wait to wait for a web page to load before interacting with any web elements on the page.

  • Fluent wait: A fluent wait is a type of wait that combines the features of explicit and implicit waits. For example, you could use a fluent wait to wait for a web element to be visible for a certain amount of time before interacting with it.

In addition to these basic waiting strategies, you can also use more advanced waiting strategies in BiDi WebDriver, such as:

  • Asynchronous wait: An asynchronous wait is a type of wait that waits for a specific asynchronous operation to complete before proceeding. For example, you could use an asynchronous wait to wait for an AJAX request to complete before interacting with the web page.
  • Conditional wait: A conditional wait is a type of wait that waits for a specific condition to be met before proceeding, or for a certain amount of time to elapse before proceeding. For example, you could use a conditional wait to wait for a web element to be visible, or to wait for a certain amount of time to elapse before giving up and proceeding.

Which waiting strategy you choose will depend on the specific needs of your test case. However, it is important to note that not all waiting strategies are supported by all BiDi WebDriver implementations. Be sure to check the documentation for your specific BiDi WebDriver implementation to see which waiting strategies are supported.
