Sample Multiple Unit Test Project

Long time no post...

Anyway, someone asked me if I could upload a working test project that shows my AutoTest header in use, so click here to download test.zip which includes two sample test classes and a main.cpp that shows two ways to start the tests running.

Open the test.pro file using Qt Creator, build it and let it rip and you should see output that looks something like this:

********* Start testing of Test2 *********
Config: Using QTest library 4.6.2, Qt 4.6.2
PASS : Test2::initTestCase()
PASS : Test2::test1()
FAIL! : Test2::test2() Compared strings are not the same
Actual ("Hello"): Hello
Expected ("World!"): World!
test2.cpp(14) : failure location
PASS : Test2::cleanupTestCase()
Totals: 3 passed, 1 failed, 0 skipped
********* Finished testing of Test2 *********
********* Start testing of Test1 *********
Config: Using QTest library 4.6.2, Qt 4.6.2
PASS : Test1::initTestCase()
PASS : Test1::test1()
FAIL! : Test1::test2() '1 == 0' returned FALSE. ()
test1.cpp(14) : failure location
PASS : Test1::cleanupTestCase()
Totals: 3 passed, 1 failed, 0 skipped
********* Finished testing of Test1 *********


I hope you find this useful - it has certainly made my life easier when using QTestLib.

  5. Rob, this is great, thanks.

    However, could you clarify how you set up your folders and paths when testing a project?

    Qt Creator default is for the main project and test project to live in separate folders (and for their source and build to also remain separate).

    Including the main project's headers in the test project is simple (just add to the INCLUDEPATH in the .pro file), but I'm so far unable to get the test project's linker to find the main project's .o files and the symbols therein.

    Can you help?
    Regards
    Jay.

  8. Rob, it is great.
    Could I translate this into Chinese and put it on my blog? For blogspot.com is blocked by the Chinese government.
    Of cause I would put the source link there.

  10. Hi Rob,
    Why did you skip line at the end of test file
    #include "some_file.moc"?
    Is it no longer necessary when we have yours implementation?

  11. Great stuff, but I am afraid that ./testBin -function returns only the test functions from the last added class file to the .pro in HEADERS.

  15. Rob, what license do you provide your code with?
    Would it be possible to use it in the commercial project?

    1. Use it however you like, just don't take credit for it. Commercial projects are fine.

    2. Thank you. Really useful!
      It would be nice if you would add a license/author comment to the top of the file.
