Calling one TEST_F in another TEST_F in gtest - c++

Question

I have a test suite in gtest.My Test Fixture class has two tests,one is Test_F(functional),Test_F(performance).
I have the implementation in such a way that Test_F(performance) is dependent on the run of Test_F(functional).
I want to handle the case,where when Test_F(functional) is disabled.So,my approach is calling Test_F(functional) from inside Test_F(performance).
I am not sure,how this is done in gtest,calling a test_function,inside another test_function.
Any help is appreciated.

AFAIK there's no option to call test function inside another test function. However, to share the code between test cases, you can define a helper method in the test suite:
class FooBarTestSuite : public ::testing::Test {
public:
TestSuite() {
// init code goes here
// foo and bar are accessible here
}
~TestSuite() {
// deinit code goes here
// foo and bar are accessible here
}
void CommonCode() {
// common test case code here
// foo and bar are accessible here
}
ClassFoo foo{};
ClassBar bar{};
};
TEST_F(FooBarTestSuite, PerformanceTest) {
CommonCode();
// performance-specific code here
}
TEST_F(FooBarTestSuite, FunctionalTest) {
CommonCode();
// functional-specific code here
}
In order to run a specific test case, use --gtest_filter=*Performace* or --gtest_filter=*Functional* as the parameter.
