# @file    junit-failing-stderr.bash.failing - Tests the junit reporter's
#          ability to propogate the stdout and stderr of failing `.bash` tests.
#
#          `.failing`: the JUnit reporter prints a vauge and misleading failure
#          message for failing `.bash` tests, ignoring both its stdout and
#          stderr.

### Act
