Adding Unit Test in XCode 3.2.

Some Objective C links:

Learning Objective C
About Unit Tests

Adding Unit Test in XCode 3.2 is very easy, here is a simple note on this:

  1. Create an objective C application, name it ‘MyApp’, build and run, you see an empty window pops up.
  2. Right click ‘Targets’, Add/New Target, choose ‘Unit Test Bundle’, set Target name to ‘Unit Tests’
  3. When Target “unit Tests” info pops up, under ‘General’, ‘Direct Dependencies’, add ‘MyApp’.
  4. Right click ‘Unit Tests’ under ‘Targets’, build ‘Unit Tests’.
  5. You see following error, because there is no test yet.
  6. "Command /bin/sh failed with exit code 1"
  7. Add a new group, name it ‘Tests’.
  8. Right click, add file, choose ‘Objective C test case class’, name it ‘MyTest’, be sure target is: ‘Unit Tests’, uncheck ‘MyApp’ if it is checked. do the step 4 again, passed? if yes, proceed to next step.
  9. Add a test to MyTest.m
  10. -(void)testCase1;
    	STAssertEquals(10, 20, @"equal?");

    build ‘Unit Tests’ again, you will see an error reported:

    testCase1] : '10' should be equal to '20': equal?

    that means our test is working, set the statement above to:

    STAssertEquals(10, 10, @"equal?");

    build ‘Unit Tests’ again, passed!
