I have noticed that you have introduced the stacktrace variable to validate the
stacktrace. The error objects already have a stack trace in them it is not
necessary to add a stacktrace object to the catch
block.

For instance:
Expect.isTrue(error.stackTrace().contains(...));
should also work.

What you have is also fine, I am not asking you to change the code, just an
observation.
