Re: [Vala] Using TestCase class: assert (this is Object) fails in method, but not in constructor

This is a nice pull request even, I've merged it.

Is there a simple way to automatically detect and fill the tests lists?

Also, what extra features would be nice to see in this template ?

Thanks!

You're missing support for `make test`.

This is a bit more complicated than it needs to be since recent
versions of CMake will complain if you try to create a "test" target;
they've decided to reserve it for their ctest framework, so the only
real choice is to use ctest.

ctest is really geared towards executing multiple small test programs
instead of one monolithic test, but you can get around that by running
the same executable multiple times and having and only executing a
subset of the tests each time.  If you don't, the ctest output will
always treat your tests as a single test, and the usefulness of reports
will be quite limited.

If you want an example, you can look at
<https://github.com/quixdb/squash/blob/master/tests/CMakeLists.txt>; it
is for C tests using µnit not Vala tests using glib, but that only
makes a difference in how you build the executable… the ctest
integration part is the same.

Assuming your executable is `my_project_unit_tests', you would want
something like this:

    # Enable ctest
    enable_testing()

    # Build your executable here, you'll have to figure this part out
    # on your own, it's project-specific.
    add_executable(my_project_unit_tests …)

    # List of tests in the `my_project_unit_tests' executable that you
    # want to execute.  The project currently only has a single test,
    # "/my_class/foo", so I've added a few more so you get the idea.
    set(MY_PROJECT_TESTS
      /my_class/foo
      /my_class/bar
      /my_class/baz
      /your_class)

    foreach(test_name ${MY_PROJECT_TESTS})
      add_test(NAME ${test_name}
        COMMAND $<TARGET_FILE:my_project_unit_tests> -p ${test_name})
    endforeach(test_name)

The only line here that really needs an explanation is the second to
last.  The $<…> thing is a generator expression; see <https://cmake.org
/cmake/help/v3.0/manual/cmake-generator-
expressions.7.html#manual:cmake-generator-expressions%287%29>.  In that
case it will just be the path to the my_project_unit_tests executable.
 The `-p ${test_name}' part just tells the executable to execute only a
specific test instead of all of them.

Once you're done, you should be able to run the tests with either `make
test` or by just running `ctest` directly.

Also, instead of the build.sh script, I'd like to suggest
<https://github.com/nemequ/configure-cmake/>.

Steven,

Since you brought it, I took the liberty to commit a project template
with my current setup of using Atom + Vala + Gee TestCase +
Cmake.

It is here: https://github.com/felipe-lavratti/vala-unittests-cmake

Hope it helps.

I'm in the process of implementing the gee test suite into my
project. So far so good. The test suite was easy to figure out. So
far my biggest problem has been trying to figure out how to setup
CMake for it all to work.

Thank you,
Steven N. Oliver

You may also find the Gee.TestCase class suits your needs - it
certainly
makes the tests easier to read and is more xUnit like in its
approach than
the 'naked' GLib Test classes.

Gives a good overview - and if I recall the GXml tests that Daniel
mentioned uses it as well.

GXml have a test suite may you want to check. I has more than 50

cases.

fails in

method, but not in constructor


Have a look at this code:

    public class Tests : Object {

        public Tests () {
            assert (this is Object); // THIS ASSERTION PASSES
            ts = new TestSuite ("dot_cap_dimmer") ;
            ts.add (new TestCase ("construction",
(TestFixtureFunc)
setup, (TestFixtureFunc) test_construction, (TestFixtureFunc)
teardown)) ;
            TestSuite.get_root ().add_suite (ts) ;
        }

        void setup(void * fixture) {
            assert (this is Object);  // THIS ASSERTION FAILS
            this.cut = new DotCapDimmer () ;
            this.cut.on_change.connect (slot) ;
            this.called = false ;
        }
        ...
     }

Would anyone know what happens to the `this` variable when
called
from the TestCase ? How came it is no longer an Object
anymore ?



You need to instantiate your fixture so it has `this` to act
upon.
Your fixture should be a separate object to the test.
As an outline;


void main( string[] args ) {

  Test.init(ref args);
  TestSuite suite = new TestSuite( "DotCapDimmer" );
  TestSuite.get_root ().add_suite (suite);

  MyTestFixture fixture = new MyTestFixture();
  suite.add( new TestCase ( "MyFirstTestCase", fixture.set_up,
(TestFixtureFunc)test_my_first_test, fixture.tear_down ));
  Test.run();
}

void test_my_first_test( MyTestFixture fixture ) {
    // do testing

}



I put the test in a namespace like
UnitTest.ModuleDirectory.FilenameOfClassToBeTested

There is also g_test_add_data_func_full () instead, but I
haven't used
that yet.
