Build Qt Tests with CMake

Question

Can anyone give me an example of some QT test code and a CMakeLists.txt that build with Cmake and ran with CTest. I can't seem to find any!

Answer 1

Here is an example of using cmake 2.8.11 and Qt5.2. Note that cmake now supports testfiles with a .moc-include at the bottom.

CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.11) project(foo)  enable_testing()  # Tell CMake to run moc when necessary: set(CMAKE_AUTOMOC ON)  # As moc files are generated in the binary dir, tell CMake # to always look for includes there: set(CMAKE_INCLUDE_CURRENT_DIR ON)  find_package(Qt5Test REQUIRED)  add_executable(foo foo.cpp) add_test(foo foo)  target_link_libraries(foo Qt5::Test) 

foo.cpp:

#include <QTest>  class Foo : public QObject {     Q_OBJECT private slots:     void t1() { QVERIFY(true); } };  QTEST_MAIN(Foo) #include "foo.moc" 

Answer 2

An example taken from Charm (Tests/CMakeLists.txt):

SET( TestApplication_SRCS TestApplication.cpp ) SET( TEST_LIBRARIES CharmCore ${QT_QTTEST_LIBRARY} ${QT_LIBRARIES} )  SET( SqLiteStorageTests_SRCS SqLiteStorageTests.cpp ) QT4_AUTOMOC( ${SqLiteStorageTests_SRCS} ) ADD_EXECUTABLE( SqLiteStorageTests ${SqLiteStorageTests_SRCS} ) TARGET_LINK_LIBRARIES( SqLiteStorageTests ${TEST_LIBRARIES} ) ADD_TEST( NAME SqLiteStorageTests COMMAND SqLiteStorageTests ) 

The only difference to a normal executable is that you call ADD_TEST macro. Have a look at e.g. Charm to see it in action.
