This option mimics the fgfs option of the same name. However for the test suite
option, additionally the SG_POPUP, SG_DEV_WARN and SG_DEV_ALERT priorities are
supported.
The default test suite output has been modified to only show the interleaved log
with the logging priority set to the command line supplied value or defaulting
to SG_INFO.
Each of the global logstream priorities are captured into its own
std::ostringstream stream, all held together in the test suite global _iostreams
class instance. This object can be obtained by calling getIOstreams(). The
streams are captured using the StreamLogCallback class, which is a simple
modification of the simgear FileLogCallback class, registered with the global
logstream's addCallback() function.
When tests fail, all of contents the different simgear logstreams are now
reported. The failure report consists of the following sections:
- Failure information.
- SG_BULK simgear logstream (all messages).
- SG_BULK only simgear logstream.
- SG_DEBUG only simgear logstream.
- SG_INFO only simgear logstream.
- SG_WARN only simgear logstream.
- SG_ALERT only simgear logstream.
- Combined STDOUT and STDERR streams.
Any empty sections, except for SG_BULK, will not be shown.
A large number of improvements have been made by subclassing the CppUnit classes
and overriding the base functions, including CompilerOutputter, TestListener,
and TextTestRunner. All IO has also been captured by the test runner.
The result is that during the test suite run, only the characters '.', 'F', and
'E' are output for a pass, failure and error state. At the end of each test
suite category, all failures and errors are reported in full detail, including
the different captured IO streams. A final synopsis is printed out, improving
the overview in the case of too many tests failing.
For the fgCompilerOutputter class, the printSuccess(), printFailureReport(),
printFailureDetail(), and printSuiteStats() functions have been replaced to
implement the above printout design. The class also stores the std::vector of
TestIOCapt structures for the final printouts.
The fgTestListener class handles the events from the running of the test suite.
The startTest() and endTest() functions are used for IO capture. The IO is
placed into a TestIOCapt data structure, with one std::string for holding the
combined STDOUT and STDERR IO, and another for the SG_LOG IO. If failures
occur, the TestIOCapt structure is appended to the fgCompilerOutputter vector.
The startTest() and endTest() functions are also used for starting and stopping
a timer to allow the full test suite to be timed. And the addFailure() function
simply registers test failures or errors.
The fgTestRunner class overrides the CppUnit::TextTestRunner::run() function,
simply to prevent the base method from spawning a second test listener, causing
the test output to be duplicated.
Some auxiliary formatting functions have been added to print out titles,
sections, and synopsis summary lines.
