Continued from previous, Now suppose you have a shared library by the name which consists of functions like sum and diff. Notes and samples for CUnit test framework for C. To test with C Unit, you create a C program that, when run, tests your code and displays the. First, we need to install CUnit libraries. I use Ubuntu, so all that I had to do was # apt-get install libcunit1 libcunit1-doc libcunit1-dev.

Contributed by Susan Morgan March [Revision number: A managed project is created with a logical folder called Test Files, where you can manage unit tests for the project. You can create tests directly under this Test Files folder or organize them in logical sub folders.
A test node in the Test Files folder is a special folder with test-related actions. When a test is built, it will exclude the main file from the project and otherwise use all other project settings.
The IDE supports only CUnit, CppUnit and its own “simple” output format, which means your tests should produce output of one of these types of tests. The IDE provides templates for unit tests: The tutorial does not explain the CUnit or CppUnit testing frameworks. You need to consult the documentation for those frameworks for information about how to use them. To follow this tutorial, you must install CUnit on your system first.
The CUnit documentation is included in the CUnit download, or you can view it at http: On Linux systems, you should be able to install libcunitl, libcunitl-doc and libcunitl-dev packages from your package repository.
The instructions below assume you downloaded the file CUnit If your download file has a different name be sure to specify your actual CUnit download file and the actual directory where you saved it. You can get the GNU build system components from the Oracle Solaris 11 package repository with the following commands:. These instructions assume you downloaded the file CUnit In Cygwin you can install CUnit using the standard Cygwin installer, setup-x The CUnit package is located in the “Libs” category and you can install it in the same way you install other packages.
Be sure to use the correct version. You can install CUnit by selecting it in the Libs category in the setup program. To explore the unit test features, you should first create a new C Application: Accept the defaults for all other options.
In the Projects window, open the Source Files folder and double-click the main. The file’s content is similar to that shown here: To give the program something to do, replace the code in the main.
When you are developing an application, it is a good idea to add unit tests as part of your development process. Each test should contain one main function and generate one executable.
For example, if you installed CUnit in Windows to C: The generated test is a stub that you must edit to make useful tests, but the generated test can be run successfully even without editing. The IDE provides a few ways to run tests. You can right-click the project node, or the Test Files folder, or a test subfolder, and select Test.
The IDE opens a new Test Results window, and you should see output similar to the following, which shows that the test fails. You can also run the debugger by right-clicking a test in the Test Results window and selecting Debug.
The C simple test uses the IDE’s own simple test framework. You do not need to download any test framework to use simple tests. The if statement should test a condition that, if true, indicates that the test failed.
The if statement in the generated test sets the condition to be true by setting it to 1, so the test always fails when you run it unmodified. The message option enables you to make the test print out a message about the test failure. If you do not see testNew passed, click the green check button in the left margin of the Test Results window to display tests that passed.
c – A good tutorial for CUnit? – Stack Overflow
The if statement should test for a condition that if it is not true, the test fails. They are used for console output. This opens a terminal window at the working directory of the current project. In the terminal, type the commands shown in bold: Note that some make output has been deleted.

Notes and samples for CUnit test framework for C
Version 7 or 8. C Unit Testing Framework project on sourceforge. See the appropriate section for installation instructions for your platform: In a terminal window, unpack the CUnit You can get the GNU build system components from the Oracle Solaris 11 package repository with the following commands: Your system may report something different, so make a note of it because you need to specify the path in the next command. Configure the Makefile with the following command.
Change the Make Command entry to make. On Windows 7 and above, type var in the Start menu’s search box to quickly find a link to Edit the system environment variables.
Select the Advanced tab and click Environment Variables. Click OK in each dialog to save the change. Start the IDE and continue to the next section. Create the Project for the Tutorial To explore the unit test features, you should first create a new C Application: Build and run the project to make sure it works by clicking the Run button yutorial the IDE toolbar. The output should look cunut to the following if you enter 8 as the integer: You might need to press Enter twice on some platforms.
Add CUnit Tests to the NetBeans Managed Project When you are developing an application, it is a good idea to add unit tests as part of your development process.
In the Projects window, right-click the main. A wizard opens to help you create the test. In the wizard’s Select Elements window, click the checkbox for the main function. This causes all the functions within main to also be selected. In this program, there is only one other function, factorial. The New CUnit Test folder contains the template files for the test.
You can add new files to the folder the same way you add source files to a project, by right-clicking the folder. Expand the New CUnit Test turorial, and see that it contains a file newcunittest. Notice that the Test Results window is split into two panels.
The right panel displays the console output from the tutoria. The left panel displays a summary of the passed and failed tests and the description of failed tests. The Test Results window should indicate that thtorial test passed. A new test folder called My CUnit Thtorial is created and it contains a mycunittest. Mouse over the failed test to see more information about the failure. Click the buttons in the left margin of the Test Results window to show and hide tests that pass or fail.
The debugger toolbar is displayed. Click the Step Into button to execute the program one statement at a time with each click of the button. In the wizard’s Select Elements window, click the checkbox for the main function, then click Next.
Expand the New C Simple Test folder, and see that it contains a file newsimpletest. This file should be open in the source editor.
Run the test to see that it generates a failure shown in the Test Results window. Next you edit the test file to see tests that pass. The new function is: In the main function, copy the lines: There are three occurrences that need to be changed.
The Test Results should look as follows:
