Add debug output to result

[sven]

Hi Sam,

I'm currently using bats but have no idea how to dig deeper in a test case when something goes wrong.

Example testcase:

    @test "build documentation" {
        [ -d "doc_dir/" ]
        pushd doc_dir/
        [ -e "Makefile" ]
        make
        [ -e "documentation.pdf" ]
        popd
    }

So if any of the above fails, I only see that the test fails and need to debug the failing line by hand. In bash I can do a set -x to see the lines as they are executed. Is it possible to do something like this in bats?

Thanks
Sven

Bats will now tell you the test filename and line number that triggers the failure: bc72b85

Recently we wanted to conveniently enable debug out of the full output of run commands in tests. We did not find a really satisfying solution, but stumpled upon this issue immediately. So adding for all the lost souls with the same problem:

We worked around it by adding some debug code to the teardown() { } function, which has all necessary variables in scope.
