Suppose I have an interface iface and a couple of its implementations A and B. Now, object of classes A and B are constructed by reading certain files f1,f2,...,fm. That is, there are m objects, and if you consider the 2 implementing classes A and B, there are 2m objects overall.
Now, https://github.com/google/googletest/blob/master/docs/advanced.md#how-to-write-value-parameterized-tests is a good starting place for automating the step of feeding the filenames f1,...,fm to the constructors. One then simply uses INSTANTIATE_TEST_CASE_P(MyGroup, BarTest, testing::Values(<some-way-of-getting-filenames>)).
On the other hand, there is a concept of Typed-Test: on is able to supply different implementations of an interface, like so
typedef Types<A,B> impls;
INSTANTIATE_TYPED_TEST_CASE_P(MyName, // Instance name
FooTest, // Test case name
impls); // Type list
Here, FooTest is defined as
template<class T>
class FooTest : public ::testing::Test {
//...
}
again according to the documentation/sample at https://github.com/abseil/googletest/blob/master/googletest/samples/sample6_unittest.cc,
whereas BarTest is defined as
class BarTest : public ::testing::Test, public ::testing::TestWithParam<const char*>
Now I can see that what I need is a combination of INSTANTIATE_TEST_CASE_P and INSTANTIATE_TYPED_TEST_CASE_P, over a class FooBarTest that derives from testing::Test, TestWithParam, and also has a template parameter T. The question is, is this possible? Is there such a macros?
