using googletest in eclipse: how?

Question

I've downloaded google test, but now I've no idea on how to link it to my project in eclipse. Should I add it as a source folder? Should include it as g++ included library? And how can I run test then?

Answer 1

Using Riga's excellent answer, here is a summary of how I got it to work:

1. Created a new C++ project in Eclipse (I chose Executable > Empty Project)
2. Downloaded googletest 1.5.0, untarred, and ran ./scripts/fuse_gtest_files.py . <project-dir>/contrib
3. Back in Eclipse, excluded the contrib directory from the Release build configuration, and added <project-dir>/contrib to the include directories (odd, I know)
4. Added a src directory and added a class named Foo (see below for the contents of Foo.h--I left Foo.cpp empty for now)
5. Added a test directory in Eclipse, excluded it from the Release build configuration, added <project-dir>/contrib to the include directories, and added new source files FooTest.cpp and AllTests.cpp (see below for contents)
6. Built and ran the project!

Foo.h:

#ifndef FOO_H_
#define FOO_H_
class Foo {
public:
  virtual ~Foo();
  Foo();
  bool foo(void) { return true; }
};
#endif /* FOO_H_ */

FooTest.cpp:

#include "gtest/gtest.h"
#include "Foo.h"
namespace {
  class FooTest : public ::testing::Test {
  protected:
    Foo foo;
  };
  TEST_F(FooTest, Foo) {
    ASSERT_TRUE(foo.foo());
  }
}

AllTests.cpp:

#include "gtest/gtest.h"
#include "FooTest.cpp"
int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

Here are the detailed steps:

1. In Eclipse, open the File menu and select New > C++ Project
2. Project Type: Executable > Empty Project
3. Toolchain: Linux GCC
4. Click Finish
5. Open a terminal and cd /tmp
6. wget http://googletest.googlecode.com/files/gtest-1.5.0.tar.bz2
7. cd gtest-1.5.0/
8. ./scripts/fuse_gtest_files.py . <project-dir>/contrib
9. Back in Eclipse, right-click on the project folder in the Project Explorer pane, then select Refresh
10. In the Project Explorer pane, right-click on the contrib folder, select Exclude from build...*, untick only the **Release box, and click OK
11. Right-click on the contrib folder and select Properties > C/C++ Build > Settings > Tool Settings tab > GCC C++ Compiler > Directories
12. Click on the Add... button, then the Workspace... button, then select <project-name>/contrib and click OK to add the directory
13. Click OK once more to accept your changes to the build settings
14. Right-click on the project in the Project Explorer pane and select New > Folder, enter src as its name, and click OK
15. Right-click on the src folder in the Project Explorer pane and select New > Class, name it Foo, then click OK (see above for contents of Foo.h; Foo.cpp can be left as is)
16. Right-click on the project in the Project Explorer pane and select New > Folder, enter test as its name, and click OK
17. Follow the steps above to add <project-name>/contrib and <project-name>/src as include directories to the test directory
18. Right-click on the test folder, then select New > Source File to add AllTests.cpp to the test folder, then repeat the same steps to add FooTest.cpp (see above for contents)
19. Right-click on FooTest.cpp and select Exclude from build..., click the Select All button, then OK
20. Right-click on the project in the Project Explorer pane, and select Properties > C/C++ Build > Settings > Tool Settings tab > GCC C++ Linker > Libraries, then click the Add... button, enter pthread (required by googletest), click OK to add the library, then OK once more to accept the changes
21. Hit Ctrl-b to build the project
22. Hit Ctrl-F11 to run the project
23. Victory!
