The https://www.playframework.com/documentation/2.8.x/ScalaFunctionalTestingWithScalaTest page has a link to a nonexistent file in the repo https://github.com/playframework/playframework/edit/2.8.x/documentation/manual/working/scalaGuide/main/tests/ScalaFunctionalTestingWithScalaTest.md .
I wanted to make a PR to the .md file by adding a missing implicit import which is required for some of the code samples but this file is not in the 2.8.x tests directory.
