Unit testing

[johu]

I've just committed a few unit tests for the new VCU code (far from complete).

Here's the source: https://github.com/jsphuebner/stm32-sin ... _can2/test

Thought I'd introduce the little "framework" here. Yes I know there's many frameworks but I didn't feel like learning any and it was a good opportunity to brush up my C++ skills.
It consists of the two files "test.h" and "test_main.cpp" and the Makefile.

For adding a series of tests you create a cpp file:

Code: Select all

#include "test.h"

class MyTest: public UnitTest
{
   public:
      MyTest(const std::list<VoidFunction>* cases): UnitTest(cases) {}
      //optional
      void TestSetup();
      void TestCaseSetup();
};

void MyTest::TestSetup()
{
   //Run some initialization once before the test cases
}

void MyTest::TestCaseSetup()
{
   //This code is run before each test case
}

//Test case 1
void TestFu1()
{
   ASSERT(1==1); //run some code and do tests
}

//Test case 2
void TestFu2()
{
}

//Finally, register with the framework
REGISTER_TEST(MyTest, FestFu1, TestFu2);

Of course your test file also has to be added to the Makefile (maybe this can be automated with some wildcard?)

The output then looks like this:

Code: Select all

You'll find the test_vcu.cpp is full of stubs/mocks. These should be moved to separate file.
Maybe I'll add those files to libopeninv/test
