Hi, I'm trying to setup an unit tests for an application. Ideally I
would like all my unit testing code to be in seprate project compiled
into a bundle. This way if a new file is added to the application's
project you don't have to add it to the unit test project.
Is this possible ? How does the unit test code link to the
application's
code ? In the OCUnit distribution the example
Examples/Testable/ApplicationBundle seems to do what I want.
No, this is a different thing: a bundle which includes tests. This is a
project that can be tested in isolation. This is also an example from
the ProjectBuilder era which has not been ported to Xcode. The easiest
way to create a bundle with tests in Xcode is simply to create a new
project using the "Cocoa bundle + Test" template.
To do what you want would require, I think, your application to be
notified that the bundle executable code is loaded and then launch the
tests. So having to instrument your app like this does not seem a good
idea if what you want is to completely separate the tests from target.
This is what I would do:
- Put your tests in a framework instead of a bundle, say
MyTests.framework
- Launch your application from a Terminal, force it to load the test
framework, and to launch the tests. For instance, in tcsh:
% setenv DYLD_FRAMEWORK_PATH ~/Developer/Builds
% setenv DYLD_INSERT_LIBRARIES
~/Developer/Builds/MyTests.framework/MyTests
% ~/Developer/Builds/MyApp.app/Contents/MacOS/MyApp -SenTest All
The application will be launched, the tests will run, the application
will quit.
We, as most users it seems, prefer to run our tests directly from Xcode
after compiling, so we have not updated Shikenjo, our graphical user
interface to run tests, and that's why you have to use the Terminal to
do this. Upgrading Shikenjo to do so would not be difficult.
Does this help?
