For example, if tests don't run at all, the test framework might be trying to open a URL that isn't valid on your machine. This problem becomes clearer if you see the page fail in the browser. To make the test framework show the browser as it runs the tests, set `WEBDRIVER_HEADLESS=false`. For example: ```shell cd gitlab/qa WEBDRIVER_HEADLESS=false bundle exec bin/qa Test::Instance::All http://localhost:3000 ``` ## Enable logging Sometimes a test might fail and the failure stack trace doesn't provide enough information to determine what went wrong. You can get more information by enabling debug logs by setting `QA_LOG_LEVEL=debug`, to see what the test framework is attempting. For example: ```shell cd gitlab/qa QA_LOG_LEVEL=debug bundle exec bin/qa Test::Instance::All http://localhost:3000 ``` The test framework then outputs many logs showing the actions taken during the tests: ```plaintext [date=2022-03-31 23:19:47 from=QA Tests] INFO -- Starting test: Create Merge request creation from fork can merge feature branch fork to mainline [date=2022-03-31 23:19:49 from=QA Tests] DEBUG -- has_element? :login_page (wait: 0) returned: true [date=2022-03-31 23:19:52 from=QA Tests] DEBUG -- filling :login_field with "root" [date=2022-03-31 23:19:52 from=QA Tests] DEBUG -- filling :password_field with "*****" [date=2022-03-31 23:19:52 from=QA Tests] DEBUG -- clicking :sign_in_button ``` ## Tests don't run at all This section assumes you're running the tests locally (such as the GDK) and you're doing so from the `gitlab/qa/` folder, not from `gitlab-qa`. For example, if you receive a `Net::ReadTimeout` error, the browser might be unable to load the specified URL: ```shell cd gitlab/qa bundle exec bin/qa Test::Instance::All http://localhost:3000 bundler: failed to load command: bin/qa (bin/qa) Net::ReadTimeout: Net::ReadTimeout with # ``` This error can happen if GitLab runs on an address that does not resolve from `localhost`. For example, if you set GDK's `hostname` [to a specific local IP address](https://gitlab.com/gitlab-org/gitlab-qa/-/blob/master/docs/run_qa_against_gdk.md#run-qa-tests-against-your-gdk-setup), you must use that IP address instead of `localhost` in the command. For example, if your IP is `192.168.0.12`: ```shell bundle exec bin/qa Test::Instance::All http://192.168.0.12:3000 ```
