Testing a framework using SenTestingKit and the debugger

Testing a framework using SenTestingKit and the debugger

  • Subject: Testing a framework using SenTestingKit and the debugger

I am trying to test a framework using Xcode 2.1 and the included SenTestingKit. Things aren't going too badly, but I need some help running test cases with the debugger. My system is a dual G5, with O SX 10.4.2 running.

My problem is my test will run in the debugger, but will not stop at my breakpoints and let me step through my test case code.

If somewhat could tell me what is wrong, I would be most appreciative.

Here's how I've got the whole thing set up:

I called my project AFramework.

I created my test target using the instructions in Apple's Unit Testing Guide. That didn't have the specifics for how to set it up if you are testing a framework, so I ended up with the following settings:

    test target name is AFramerworkTestTarget.
    test target is dependent on AFramework
    no Bundle Loader specified
    no Test Host specified
    no Test Rig specified
    added to the other linkers flags: -framework AFramework

At this point the tests run when I build AFramerworkTestTarget and I can see all of the test results and my NSLog output in the build results window. 

So far, so good. However, a couple of tests failed, so I would like to step through the test case code in the debugger to see what's going on.

Using info gathered from this list and the instructions in Apple's Xcode 2.1 User Guide I created a custom executable that points to otest and has the following settings:

General Pane:
    executable path: /Developer/Tools/otest
    working directory set to Build Products directory

Arguments Pane:
    Arguments to be passed on launch are:
        -SenTest All
         AFramerworkTestTarget.octest

    Variables to be set in the environment are:
        DYLD_INSERT_LIBRARIES = /System/Library/PrivateFrameworks/DevToolsBundleInjection.framework/DevToolsBundleInjection
        XCInjectBundle = $(BUILT_PRODUCTS_DIR)/AFramerworkTestTarget.octest


To run, first I click "Build" and get the results in the build results window. Then I click "Debug" to run it in the debugger.

This is the debugger console output, which shows it running in the debugger, having knowledge of the breakpoints I set (see the lines that say pending breakpoint resolved), but never stopping at the breakpoints or showing my test code in the debugger window.
