[Cppunit-devel] testing through an array: TestCallerIndexed?

[John P. <jo...@cu...>]

Hi there

I've been using CppUnit happily for a while now but I have been a bit
frustrated by one particular lack for which I haven't been able to come
with a workaround.

What I would like to be able to do is to set up a vector or array
containing sets of numerical values, and then pass each set of values to
a test method.

At present, I do this using a for loop inside a TestMethod. This has the
disadvantage that CPPUNIT_FAIL will cause remaining tests not to be
executed. So although it picks up failures fine, it gives no indication
of the spread of the errors throughout the array.

What I thought might be the correct solution was to extend the
TestCaller class. I thought about having TestCallerIndexed, and adding a
TestCaller::runTest(int index) method that would somehow pass an integer
value to the TestMethod assigned to the TestFixture. But then I thought
that this probably wouldn't work  - because the TestMethod prototype
would have changed, so it wouldn't be possible to assign it to the
TestFixture.

Has anyone else had similar problems, and worked out a nice solution
that they would care to share?

I've also posted this on the sf.net forums for CppUnit.

Cheers
