Junit5: Why are strange characters in console output?

Created on 2 Oct 2020 · 5Comments · Source: junit-team/junit5

I use org.junit.platform.console.ConsoleLauncher as an eclipse run config.

Output:

I would assume you've probably run the tests in a console that doesn't have support for ANSI escape codes. If you were in a console that supported them you'd see output that looked more like the following.

�[32m✔ SUCCESSFUL
