That, great news, I'm especially curious about this line here:

[ExUnit] Show code snippet from test source file in case of test errors

ExUnit backtraces have historically been a bit hard to read sometimes IMHO.

[josevalim]

This line is about showing a snippet of the test when a test fails. We did this before but only for assertions.

I am afraid this change will not improve the qualify of the stacktrace itself.

If you run into a situation where the test report is less than ideal, please open up an issue so we can discuss if there is something that can be done about it.
