• A ExUnit.Formatter implementation that generates a xml in the format understood by JUnit.

To acomplish this, there are some mappings that are not straight one to one. Therefore, here goes the mapping:

• JUnit - ExUnit
• Testsuites - :testsuite
• Testsuite - %ExUnit.TestCase{}
• failures = failures
• skipped = skip
• errors = invalid
• time = (sum of all times in seconds rounded down)
• Testcase - %ExUnit.Test
• name = :case
• test = :test
• content (only if not successful)
• skipped = {:state, {:skip, _}}
• failed = {:state, {:failed, {_, reason, stacktrace}}}
• reason = reason.message
• contet = Exception.format_stacktrace(stacktrace)
• error = {:invalid, module}

The report is written to a file in the _build directory.
