Diagnosing During Filters With Verbose

Diagnosing During Filters With Verbose

When VerboseLogging is enabled, Isolator++ Professional outputs detailed trace messages showing how During filters are evaluated at each level (Call, Instance, Suite).

These messages help identify why a fake was or wasn’t applied.

TEST(DuringTests, MultipleDuringFiltersUsingAModuleAndAMemberAndAThreadSucceeded)

{

    auto a = Isolator(During(A::Module("Test.dll")),IsolatorConfig::VerboseLogging);

    auto fake = a.Fake.Instance<Person>(During(A::Call(Person::GetName)));

    a.CallTo(fake->GetName())

     .During(A::Thread(GetCurrentThreadId()))

     .WillReturn("John");

    auto res = fake->GetName();

    ASSERT_TRUE(strcmp(res, "John") == 0);

}

Example output:
