FindXCTest
----------
Functions to help creating and executing XCTest bundles.
An XCTest bundle is a CFBundle with a special product-type
and bundle extension. The Mac Developer Library provides more
information in the `Testing with Xcode`_ document.
.. _Testing with Xcode: http://developer.apple.com/library/mac/documentation/DeveloperTools/Conceptual/testing_with_xcode/
Module Functions
^^^^^^^^^^^^^^^^
.. command:: xctest_add_bundle
The ``xctest_add_bundle`` function creates a XCTest bundle named
<target> which will test the target <testee>. Supported target types
for testee are Frameworks and App Bundles::
xctest_add_bundle(
<target> # Name of the XCTest bundle
<testee> # Target name of the testee
)
.. command:: xctest_add_test
The ``xctest_add_test`` function adds an XCTest bundle to the
project to be run by :manual:`ctest(1)`. The test will be named
<name> and tests <bundle>::
xctest_add_test(
<name> # Test name
<bundle> # Target name of XCTest bundle
)
Module Variables
^^^^^^^^^^^^^^^^
The following variables are set by including this module:
.. variable:: XCTest_FOUND
True if the XCTest Framework and executable were found.
.. variable:: XCTest_EXECUTABLE
The path to the xctest command line tool used to execute XCTest bundles.
.. variable:: XCTest_INCLUDE_DIRS
The directory containing the XCTest Framework headers.
.. variable:: XCTest_LIBRARIES
The location of the XCTest Framework.
