![]() ![]() Our example is inspired by this YouTube math video that attempts to visually prove a property of the Fibonacci sequence. For CTest to run these tests, the CMakeLists.txt file of both sub-projects uses the directive add_test. In our example, the first is illustrated with the BusinessLogicTest project, the second with the GUIQMLScreenTest project. The project’s unit tests are contained within CMake sub-projects that are implemented using the Qt Test Module. There are two types of these sub-projects: the ones that test the application’s business logic using Qt Test and the ones that test the application’s user interface using Qt Quick Test. To enable this, the project’s main CMakeLists.txt file must contain the following directive: enable_testing(). It can be called from the command line of the project’s build directory or from Qt Creator under the “Tools” menu. If the project is configured correctly, it’s invocation will trigger the running of all the project’s unit tests. The CMake build tool provides the program CTest as a means for unit testing. Creating a Unit Testing Project Infrastructure Using this module and illustrating it with a fun example hosted here, this blog describes how to create a Qt/ CMake project that easily supports Unit Testing. The Qt Test Module provides some tools that can facilitate this task. In the context of Graphic User Interfaces (GUI), developers are often confronted with having to write unit tests for what is typically validated by a human’s perception of the software’s look and feel. Test-driven Development (TDD), for instance, mandates that before a requirement is even implemented a corresponding test case must be written. You can debug and step-through CTest-only executables, but stack traces on individual tests aren't supported.Unit testing is becoming an essential part of the software implementation process. If you are using CTest but not the Google or Boost adapters, you see results at the CTest level instead of the individual test method level. The following illustration shows results of a CTest run using Google Test framework: However, if you are upgrading a project from an older version of Visual Studio, you may need to install those frameworks by using the Visual Studio Installer program. ![]() Those frameworks are included by default as components in the Desktop Development with C++ workload. To run testsĬTest is fully integrated with Test Explorer and also supports both the Google and Boost unit testing frameworks. To learn more about CTest, see the CMake documentation.įor more information about using CMake in Visual Studio, see CMake projects in Visual Studio. Use the enable_testing() command to enable testing, and the add_test() or gtest_discover_tests() command to add a new test. ![]() Therefore, you write and configure CTest tests just as you would in any CMake environment. To write testsĬMake support in Visual Studio doesn't involve the Visual Studio project system. Select C++ CMake tools for Windows under the list of workload components. If you need to install it on your machine, open the Visual Studio Installer program, click the Desktop Development with C++ button, then click Modify. Applies to: Visual Studio Visual Studio for Mac Visual Studio CodeĬMake (which includes CTest) is integrated into the Visual Studio IDE by default as a component of the Desktop Development with C++ workload.
