RegressionTestResult.USE_XML must now be set to True to get the JUnit
XML output.
Reduce the number of imports when --junit-xml=FILE option is not
used: 153 => 144 (-9).
After commit d0f49d2f50, the output of the
test suite is always buffered as the test output needs to be included in
the JUnit file in same cases (as when a test fails). This has the
consequence that printing or using debuggers (like pdb) in the test
suite does not result in a good user experience anymore.
This commit modifies the test suite runner so it only captures the test
output when the JUnit file is requested to fix the regression so prints
and debuggers are usable again.
