Mostly we depend on the CI actions (running automated tests and linters), but every PR also creates a feature branch on the testing/staging environments so anybody can run the app _as of that branch_ online. The URL schema is kind of like https://app-staging.foo.com/feature/add-sorting/ https://app-staging.foo.com/feature/add-sorting/ compared to the original https://app-staging.foo.com/ https://app-staging.foo.com/ given you have created a PR pointing from branch named feature/add-sorting to master. This also makes it easier for our QA engineers to test things before they get merged to master.
