Re: Help getting custom exception to print message when using the stdout reporter

[Leonard Ehrenfried]

Try overriding the method "getMessage". 

See http://docs.oracle.com/javase/8/docs/api/java/lang/Throwable.html#getMessage--

In my code I have the following exception

In my tests, there are cases where this can be thrown. When I run the tests from IntelliJ and this exception is hit, the output looks like...

com.twitter.dataproducts.clients.http.HttpRequestException was thrown.

Received unexpected status code. 

 Status Code: [422 Unprocessable Entity]

This information is super useful in debugging exactly what went wrong. 

Now when I run this same test from my command line using "-o" for the stdout reporter, all I end up getting is...

- test that failed *** FAILED ***

    com.twitter.dataproducts.clients.http.HttpRequestException:

As you can see, the all that useful information is gone. Base on the ":" trailing the exception type, I am guessing that I am just doing something wrong to get this to print out in that reporter. 

I also cannot specifically use an info() in the test as I am building up a framework for other devs to use, so setting this up to print behind the scenes is important.

As a note, I am using scalatest 3.0.

This thread got duplicated. Bill replied at https://groups.google.com/forum/#!topic/scalatest-users/HYV86iCjIn0. I'll continue over there. As I noted on that thread. overriding getMessage did not work.
