8/6/2023 0 Comments Cmake add test exampleLets begin by defining how our class should behave, it's specification. But we want to ensure that the code works, perhaps before we write either the puzzle class or the solver, so we need to write some unit tests, code that tests individual units of other code, in this case the Puzzle class. Our goal here is not to write a program to solve the puzzle ( although it is fun to do), but to just model the puzzle itself, a component of a larger puzzle solver program. Is empty at position (2,2), has tile 'D' in position (1,0), tile 'B' on position (0,1), etc. The goal is, from a scrambled state, slide the tiles around until the tiles show a particular image or spell some text.Ĭonsider a 3 by 3 puzzle with eight tiles, addressed by row and column with 0-based indexing, with labels 'A' through 'H' and an empty spot denoted by the label ' '(space). The tiles can slide left-right and up-down within the puzzle, exchanging positions with the empty location. You have probably seen these, a square array of tiles with numbers, letters, or part of an image printed on them, and one blank space. Here is where the best magic happens - we register the class with ctest.Suppose that we wanted to write a C++ class, Puzzle, that models an eight-tile sliding puzzle. void cleanupTestCase () )įinally the above uses ADD_TEST to register the test with cmake / ctest. void initTestCase () // will be called after the last testfunction was executed. Private slots : // will be called before the first testfunction is executed. Source tree so all you need to do are the easy bits - writing unit tests! I’veĪlready done much of the configuration for you in CMake and other places in the Right with that overview in mind, I will delve into a bit of detail. More fine grained control over running tests. This is normally done simply by doing make testĪfter the make install step, though I will explain other aproaches that offer Your tests should never modify this data in situ,īut rather may a temporary copy somewhere if needed. These test data shouldīe as small as possible and wherever possible you should use the existingĭatasets already there. You optionally add test data to /tests/testdata if your.Will ensure your tests actually get compiled when you type make. You ensure you have ENABLE_TESTING enabled in ccmake / cmakesetup.You add a section to the CMakeLists.txt in your tests directory that will.The Qt meta object compiler (moc) and expands your test class into a You include QtTestLib macros in your test class.One of the calls fails, the unit will fail. Return from each method to make sure it matches the expected value. Instance of a class and calls some methods on that class. The test is basically a client that creates an Since we are starting with a testing framework well after much application Practive you will probably need to write tests for pre-existing code in QGIS Immediately validate each new functional part you add with your test. When you start building your tests, and then as you implement your code you can Programming advocates suggest that the code should not even be written yet There is some code you want to test, e.g.Lets take an overview of the process before I delve into Library) and CTest (a framework for compiling and running tests as part of theĬMake build process). Unit testing is carried out using a combination of QTestLib (the Qt testing The QGIS testing framework - an overview ¶
