The QCOMPARE macro will compare the actual result of this function with its expected result and will log the result. Our BusinessLogicTest runs six unit tests (the number of rows in the table) and tests the business logicвЂ™s implementation of the Fibonacci function: uint BusinessLogic::fib(uint n) noexcept. QCOMPARE (actualresult, expectedresult )

QTest :: newRow ( 'Fib 0' ) fib (input ) It our example we leveraged the data driven testing feature of the Qt Test framework which encapsulates the input and expected output data in a table like this: The sole cpp file contains a QObject class whose slots are in fact the unit tests. It is this wizard that generated the skeleton for the BusinessLogicTest project consisting of one cpp and CMakeLists.txt file. To invoke these wizards in Qt Creator, select New, Other Projects and then Auto Test Project. For instance, the Qt Creator wizard generating unit tests also allows the usage of Google Test, Boost Test and Catch 2. Although the BusinessLogicTest uses the Qt Test framework, others could have been considered. This separation alleviates one of the main challenges in writing unit tests: making our project testable. Both the application and the BusinessLogicTest link to it. In our fun example, the business logic is generated by the sub-project BusinessLogic. The project encapsulates the business logic in its own library. In ourВ example hosted here, the binary of the application that achieves this is created by the subproject FibonacciPgm. Each click of the mouse will trigger the creation of the square whose area represents the current Fibonacci number.ДЇor instance, if the user starts the application and then clicks eight times, the program should display this: A fun example using Fibonacci Our project creates a program that draws the visual squares the presenter uses. 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 projectвЂ™s unit tests are contained within CMake sub-projects that are implemented using the Qt Test Module.В There are two types of these sub-projects: the ones that test the applicationвЂ™s business logic using Qt Test and the ones that test the applicationвЂ™s user interface using Qt Quick Test. To enable this, the projectвЂ™s main CMakeLists.txt file must contain the following directive: enable_testing(). It can be called from the command line of the projectвЂ™s build directory or from Qt Creator under the вЂњToolsвЂќ menu. If the project is configured correctly, itвЂ™s invocation will trigger the running of all the projectвЂ™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 humanвЂ™s perception of the softwareвЂ™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.

Unit testing is becoming an essential part of the software implementation process.
