Running single testsuite

[sanrao]

Hi,
   Pls explain, how to execute a single test from registry inspite of registering multiple test suites. How is the argv[] variable given to the main() passed to the test "getregistry().maketest();"

Kindly reply asap!!

Thank you,
Regards

I couldn't find anything in the FAQs or documentation, so a bit of digging and experimentation I found a way to do it.
You can pass in an argument to the getRegistry() method, so here I pass in the command-line argument if one were provided:

int main(int argc, char* argv[])
{
  // Get the top level suite from the registry
  CPPUNIT_NS::Test *suite = CPPUNIT_NS::TestFactoryRegistry::getRegistry( argc == 2 ? argv[1] : "All Tests" ).makeTest();

...

This will create only the named test suite. How do you name a test suite? Like this:

CPPUNIT_TEST_SUITE_NAMED_REGISTRATION( MyClass_test, "MyClass" );

So now in my project settings, I give the command-line argument "MyClass" and it only runs that one test. If I remove the cmd-line arg, all tests are run.

Bingo!

Cheers

OK, it turns out it's not quite as simple as that, but it's not too hard either.

You have to register the test both as a named test and as a default test, so your registration code looks like this:

CPPUNIT_TEST_SUITE_NAMED_REGISTRATION( MyClass_test, "MyClass" );
CPPUNIT_TEST_SUITE_REGISTRATION( MyClass_test );

Why the named registration doesn't register it as default also I have no idea. Double the code, double the fun??!!

Hope that helps
