OCUnit

otest

Initial execution is of the otest tool.  This is a command line tool that takes arguments of the bundle to load and test, and what should be tested in that bundle.

Comand line args are:

• -SenTest [Self | All | None]
• <TestCaseClassName/testMethodName>
• <path/to/testBundle.otest>

 
Unfortunately, several environment variables are needed as well.

• SenTestTool: 
• sets the NSUserDefaults with:
• SenTest:Self 
• loads the test bundle (as passed in on the command line)
• runs one of (if the test bundle loaded):
• runTestFromBundle:
• launchTaskFromPath:bundle: (if runTestFromBundle: returns false)
  
• runs launchTaskFromPath:bundle: (if the bundle did not load)
• SenTestTool: - (BOOL) runTestFromBundle:(NSBundle *)aBundle
• sets the NSUserDefaults with:
• SenTestedUnitPath:{the path of the passed in bundle} 
• loads the bundle
• Calls SenTestProbe +(void)runTests:
• SenTestTool: -(void) launchTaskFromPath:(NSString *)aPath bundle:(NSBundle *)aBundle (this seems to be used instead of runTestFromBundle: when the bundle is determined from a class, and not from a command line argument)
• determines the bundle the from the path
• creates an NSTask and executes it, which has the effect of calling runTestFromBundle:

SenTestingKit 

At this point,execution leaves otest and goes into the framework.

• SenTestProbe +(void) runTests:(id)ignoredValue;
• Sends the selector principalClass to all frameworks
• Loads the SenTestObserver class.  This registers the following notifications with the default notification center:
• SenTestSuiteDidStartNotification
• SenTestSuiteDidStopNotification
• SenTestCaseDidStartNotification
• SenTestCaseDidStopNotification
• SenTestCaseDidFailNotification
  
• calls run on the specifiedTestSuite. This is one of the following three (based upon the command line argument):
• [SenTestSuite defaultTestSuite]
• [SenTestSuite testSuiteForBundlePath:[self testedBundlePath]]
• [SenTestSuite testSuiteForTestCaseWithName:testScope]
• Calls hasSucceeded on the result of above.
  
• SenTest +(SenTestRun *)run;
  
• creates a SenTestSuiteRun instance initialized with the SenTestSuite
• calls performTest:SenTestSuiteRun on self
• SenTestSuite - (void) performTest:(SenTestRun *) aTestRun;
• calls setUp on self
• calls start on aTestRun
• fires SenTestSuiteDidStartNotification
  
• Calls run on each test in [self tests] (all the tests as defined in the specifiedTestSuite from above)
  
• calls addTestRun: on aTestRun with the result of the above run call.
• calls stop on aTestRun
• fires SenTestSuiteDidStopNotification
  
• calls tearDown on self
•
