Detailed Description

Replacement for junit.textui.TestRunner that helps avoid some issues with using JUnit embedded in ALMA TAT scripts.

Note that the intent is not to get rid of the output-based testing that TAT offers, but to complement it with result-based testing as JUnit proposes it, and to make the latter easier in a TAT environment. Both approaches have their merit, so chose one depending on what you want to test.

Internally calls TestRunner#doRun(Test), controlling the ResultPrinter output as well as System.out and System.err.

Fixes the following issues

  1. If the tests succeed, TestRunner produces too much output, which forces test developers to provide TAT with reference output files of all successful JUnit test runs, which seems absurd given that JUnit does all error checks already itself.
    TATJUnitRunner produces no output for successful tests, which means it suppresses Both TestRunner and TATJUnitRunner return an exit code 0 to indicate a successful run.
  2. If a test fails (either JUnit "failure" or "error"), TestRunner reports this in the execution summary, without giving any details on the problem, e.g. the assertion that caused the failure.
    TATJUnitRunner in this case becomes rather verbose and dumps on System.err Both TestRunner and TATJUnitRunner return an exit code 1 for a failure and 2 for an error.
For either failure or success, the following line is printed as the first line to stdout, so that TAT or other tools can analyze how many tests have run, and how many succeeded:
TEST_RUNNER_REPORT success/total: int/int
where int is replaced by the respective integer number.

Note that if this method should become public in the future (and thus can be called directly, rather than from run(Class), the handling of the output streams and the like must be shared properly between the two run methods.

Parameters:
suite 

void alma::acs::testsupport::tat::TATJUnitRunner::run Class  testClass  )  throws FileNotFoundException [inline, static]
 

Runs a suite extracted from a TestCase subclass.

Redirects System.out and System.err so that successful test runs will not produce any output, while in case of failure/error they get dumped to System.err.
