# Debugging tests
|
|
|
|
If your tests aren't working as you expect them to, you can inspect and debug them in the browser.
|
|
|
|
Debug specs in the browser in the same way that you debug an application.
|
|
|
|
1. Reveal the Karma browser window.
|
|
See [Set up testing](guide/testing#set-up-testing) if you need help with this step.
|
|
|
|
1. Click the **DEBUG** button to open a new browser tab and re-run the tests.
|
|
2. Open the browser's **Developer Tools**. On Windows, press `Ctrl-Shift-I`. On macOS, press `Command-Option-I`.
|
|
3. Pick the **Sources** section.
|
|
4. Press `Control/Command-P`, and then start typing the name of your test file to open it.
|
|
5. Set a breakpoint in the test.
|
|
6. Refresh the browser, and notice how it stops at the breakpoint.
