Google Test not finding any tests

So I'm working on creating my first unit tests. I'm using Google Test, the version that is currently built into Visual Studio 2017. This is an attempt at a proof of concept, so super simple.

I have a project in the solution for the test code: test.cpp

#include "pch.h"
#include "../ConsoleApplication1/ConsoleApplication1.cpp"

TEST(SumTest, FirstTest) {
  EXPECT_EQ(6, sum(2, 4));
}

TEST(SumTest, SecondTest) {
    EXPECT_EQ(1, 1);
    EXPECT_TRUE(true);
}

And I have a simple method to test in ConsoleApplication1.cpp

// ConsoleApplication1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

int sum(int a, int b);

int main()
{
    int x = sum(2, 4);
    printf("The answer is: %d \n", x);

}

int sum(int a, int b) {
    return a + b;
}

Everything compiles fine, but when I click 'Run All' from the Test Explorer menu, I get the following output:

It doesn't seem to be discovering either of the tests I'd written, and I'm not sure why.

It seems you should add RUN_ALL_TESTS into your main. See the example github.com/google/googletest/blob/master/googletest/docs/… – Konyn 7/5, 2018 at 20:45

You should not include *.cpp files as in: #include "../ConsoleApplication1/ConsoleApplication1.cpp. Second, to be able to use gtest, you need to include it (is it included in "pch.h"?). And third, gtest has a particular way to be initialized and executed. Look at the docs – Opinionative 7/5, 2018 at 20:49

@Konyn This was all I needed! – Amory 7/5, 2018 at 20:55

@Opinionative Looks like it was just the initialization that I was missing. Gtest is included from pch.h Why is including #.cpp a bad practice? – Amory 7/5, 2018 at 20:57

@NeilRuggiero I'll not get into details, but you can look here, for example: #1686704 By the way, why is gtest.h buried in pch.h? – Opinionative 7/5, 2018 at 21:16

@Opinionative Thanks for the link, much appreciated! I'm not exactly sure why gtest.h is included from pch.h, that was the way the project was set up using the built in Visual Studio tool – Amory 8/5, 2018 at 12:30

@NeilRuggiero pch means "Precompiled Header". That file is optional. You can include gtest.h directly, delete pch.h and deactivate precompiled headers in the compiler options, i.e. in the project properties under Configuration Properties --> C/C++ --> Precompiled Headers. – Frenchify 31/1, 2019 at 15:59

GoogleTest framework in the common case requires RUN_ALL_TESTS macro in main:

int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

Then you can add your tests into different cpp files and the magic under the hood will launch all of them and show nice report.

Although, you can use Google Tests even without this macro. See this answer.

Thanks so much, this fixes my issue. Accepting your answer. – Amory 7/5, 2018 at 20:55

That link is dead – Feudist 17/10, 2018 at 16:45

I have the same issue. Where should RUN_ALL_TESTS be added? In the test.cpp or ConsoleApplication1.cpp? – Gilleod 15/12, 2018 at 18:28

@Hamid, in test.cpp. There is no main function in library, if you're going to test it. – Konyn 11/1, 2019 at 9:21

@Konyn I have the same problem. However, if I add the main function in the test project it complains that main has been defined twice. This is obviuosly the case since I already have a main function in my main.cpp (part of the actual project). In that project the test framework is not included (so I don't have access to the the headers to include it there) Help please? – Yuletide 1/2, 2019 at 19:12

@AdrianKoch, it seems like you link the main project to the test project. The purpose of gmock and unit testing overall is to test separate classes. What you should do is to compile implementations of your classes (without your project entry point) and link to gmock. – Konyn 4/2, 2019 at 7:43

@Konyn Ok that makes a lot of sense. So for a c style project that only contains functions and structs I would have my functions in a separate file and only include that file to the test project? – Yuletide 4/2, 2019 at 14:3

@AdrianKoch, plain C code cannot be mocked with gmock out of the box. However, there are some tricks you can do. Take a look at this question #31989540 – Konyn 4/2, 2019 at 14:59

The answer about RUN_ALL_TESTS() in main() is close, yet there are details. Have currently discovery working without manual main.

Worth a note that setting Project Configuration -> Referenced Packages -> Google test -> Use Google Test's main Function is supposed to provide main automatically.

It may be useful to enable debug under Tools -> Options -> Test Adapter for Google Test -> General -> Print Debug Info.

After enabling, had additional entries in the log:

Found 4 test method symbols and 0 trait symbols in binary  ...  
Found 0 tests in executable ...  
Test discovery completed ...  
No test is available in ...

An actual problem was including wildcard *\*.obj in Additional Dependencies (with intention of avoiding of adding each .obj manually). This also included obj with main() from referenced project, which somehow replaced the intended by GT alternative.
Removing excessive *.obj solved the problem.

I know this thread is quite old, but I found another potential cause for this error. In my case, the test exe file could not load a DLL, and terminated without providing the test listing. I changed the test unit's output directory in the project settings to be the same as the DLL, and the tests worked fine after that.

@NuPagadi have right with his answer. If you after that still have problems, use right google test nuget. I have same code, I just switch from dyn.rt-dyn to static.rt-dyn and test explorer find all tests.
