Given this fact, we should limit the use of `before(:all)` to only those operations where a screenshot is not necessary in case of failure and QA logs would be enough for debugging. + +## Ensure tests do not leave the browser logged in + +All QA tests expect to be able to log in at the start of the test. + +That's not possible if a test leaves the browser logged in when it finishes. Normally this isn't a problem because [Capybara resets the session after each test](https://github.com/teamcapybara/capybara/blob/9ebc5033282d40c73b0286e60217515fd1bb0b5d/lib/capybara/rspec.rb#L18). But Capybara does that in an `after` block, so when a test logs in in an `after(:context)` block, the browser returns to a logged in state *after* Capybara had logged it out. And so the next test will fail. + +For an example see: <https://gitlab.com/gitlab-org/gitlab/issues/34736> + +Ideally, any actions peformed in an `after(:context)` (or [`before(:context)`](#limit-the-use-of-beforeall-hook)) block would be performed via the API. But if it's necessary to do so via the UI (e.g., if API functionality doesn't exist), make sure to log out at the end of the block. + +```ruby +after(:all) do + login unless Page::Main::Menu.perform(&:signed_in?) + + # Do something while logged in + + Page::Main::Menu.perform(&:sign_out) +end +``` |
