Typedef Documentation

Wraps a test case with setUp and tearDown function.

A TestCase is used to provide a common environment for a set of test cases.

To define a test case, do the following:

  • the case is defined by static variables
  • initialize the case state by setUp function
  • clean-up after a test by tearDown function

Each test runs in its own case so there can be no side effects among test runs. Here is an example:

 static int value1, value2;

 void setUp_MathTest ()
 {
   value1 = 2;
   value2 = 3;
 }

 ...

 CCUnitTestCase* MathTest_newTestCase ()
 {
   return ccunit_newTestCase ("MathTest", setUp_MathTest, NULL);
 }

For each test implement a function which interacts with the case. Verify the expected results with assertions specified by calling CCUNIT_ASSERT on the expression you want to test:

 void testAdd ()
 {
   int result = value1 + value2;
   CCUNIT_ASSERT (result == 5);
 }

 ...

 void MathTest_newTestCase_testAdd ()
 {
   return ccunit_newTestCase ("testAdd", "add test", testAdd);
 }

The tests to be run can be collected into a TestSuite.

 CCUintTestSuite* MathTest_suite ()
 {
   CCUnitTestSuite* suite = ccunit_newTestSuite ("MathTest");
   CCUnitTestCase* tcase = MathTest_newTestCase ();
   ccunit_addTestCase (suite, tcase);
   ccunit_addTestCase (tcase, MathTest_newTestCase_testAdd ());
   ccunit_addTestCase (tcase, MathTest_newTestCase_testDivZero ())
   return suite;
 }

Once the functions are defined you can run them. To do this, use a TestRunner.

   CCUnitTestRunner *runner = ccunit_newTestRunner (stdout);
   CCUnitTestSuite *suite = MathTest_suite ();
   runner->run (runner, suite);

A command line tool have been created for convenience. It is located in src/tools/ccunit_makeSuite.c.

A single test function object.

For each test implement a function which interacts with the case. Verify the expected results with assertions specified by calling CCUNIT_ASSERT on the expression you want to test:

 void testAdd ()
 {
   int result = value1 + value2;
   CCUNIT_ASSERT (result == 5);
 }

 ...
 int main ()
 {
   CCUnitTestResult* r;
   CCUnitTestCase* c = ccunit_newTestCase ("math test");
   CCUnitTestFunc* f = ccunit_newTestFunc ("testAdd", "add test", testAdd);
   ccunit_addTestFunc (c, f);
   r = ccunit_runTestCase (c);
   return 0;
 }
