Parameterizing a test using CppUnit

Question

My organization is using CppUnit and I am trying to run the same test using different parameters. Running a loop inside the test is not a good option as any failure will abo

Answer 1

Upon of the suggestion of Marcin i've implemented some macros aiding to define parameterized CppUnit tests.

With this solution you just need to replace the old macros CPPUNIT_TEST_SUITE and CPPUNIT_TEST_SUITE_END within the class's header file:

CPPUNIT_PARAMETERIZED_TEST_SUITE(, );

/*
 * put plain old tests here.
 */

CPPUNIT_PARAMETERIZED_TEST_SUITE_END();

In the implementation file you need to replace the old CPPUNIT_TEST_SUITE_REGISTRATION macro with:

CPPUNIT_PARAMETERIZED_TEST_SUITE_REGISTRATION ( ,  )

These macros require you to implement the methods:

static std::vector parameters();
void testWithParameter(ParameterType& parameter);

• parameters(): Provides a vector with the parameters.
• testWithParameter(...): Is called for each parameter. This is where you implement your parameterized test.
