Running automated tests that don't output formatted reports

[Peter-Frank Spierenburg]

I have a bamboo build that produces an automated test executable.

When that automated test executable is invoked, it produces some output on stdout, but that output isn't formatted in any particular way.

The important feature of the automated test executable is exit value. An exit value of zero indicates that all tests executed successfully, an exit value of one indicates that one or more tests failed.

In the Task Types window, under Tests, it lists several parsers and runners. However, they are all specific to some particular brand of testing framework, whether that be JUnit, or Mocha, or whatever. Is there a test task type that invokes a built executable and can determine from the return value whether the tests passed or failed?
