Support Stacktrace when test crashes #35
Description
Currently, when tests crashes, seems there is no stack trace. That would help a lot to investigate issue, especially for me when I migrate a project to bazel and some unit test crash.
How to reproduce:
Just put fatalError("") in unit tests or in testing swift code.
A similar issue is opened in Bazel but it seems belong the this xctestrunner: bazelbuild/bazel#8050
