It happened quite often, that a build process silently failed and passed as successful step. (Some dependency wasn’t loaded correctly or misconfigured - the build continues without errors).
Well, at the end the tests fail and you begin to search…
Normally i log in into that instance and can check the state after the tests failed.
Option to add a breakpoint before each command, like in an ide. The next commands are waiting until you click on a “continue” button.
You can log in into the instance, see the current state and modify your commands and configs. You can check the state before and after each step.
