UnitTest ++ usage

UnitTest ++ is a very small and convenient unit test tool used in the C ++ project. It provides functionality similar to CppUnit, But It minimizes the workload of case writing and makes it easier to use. All of these benefits from its clever conception of the framework, for details, refer to the source code. This tool does not support VC6 itself. I have improved it. Below is a simple comparison of CppUnit and UnitTest ++: 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?

Note: 1. Each TEST case starts with TEST, followed by the case name in parentheses, and repeated tests are not allowed. 2. Generally, use the CHECK macro to CHECK the result. For more inspection methods, refer to the source code or the documentation provided by UnitTest ++. The following lists some commonly used macros: CHECK_EQUAL (expected, actual) Check for equal CHECK_CLOSE (expected, actual, tolerance) check whether the values are equal within the tolerable range of errors (mostly used for equal floating point numbers) CHECK_ARRAY_EQUAL (expected, actual, count) check whether the array is equal. The first two parameters are array names, count is the number of elements. CHECK_ARRAY_CLOSE (expected, actual, count, tolerance) refer to the preceding two descriptions. CHECK_ARRAY2D_CLOSE (expected, actual, rows, columns, tolerance) two-dimensional array. CHECK_THROW (expression, ExpectedExceptionType) checks whether an exception of the specified type is thrown. CHECK_ASSERT (expression) checks whether UnitTest: AssertException type exceptions are thrown. 3. Each test case is automatically added to the set of test cases to be run.1.3.2. test the use of SUITSUIT can be used if you want to place a set of test cases in a group. 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?

1.3.3.

Note: 1. To use FIXTURE, you must first define a structure SomeFixture. 2. Place the code to be run in setUp into the SomeFixture constructor. 3. Place the code to be run in tearDown into the destructor of SomeFixture. 4. Members in SomeFixture can be used to test data sharing. 5. Each use case is defined using TEST_FIXTURE. Similar to the TEST macro, the defined use case is automatically added to the set of use cases to be run.1.3.4.

1. In the UnitTest ++ source code, modify the previous RunAllTests (reporter, Test: GetTestList (), 0) last parameter 0. You can set global time constraints, that is to say, the execution time of each use case must be less than this time constraint. Otherwise, use case fail. 2. You can change the reporter type to change the test result output mode. For example, XmlTestReporter is used to output the result to an xml file.1.4.2. More advanced usageLearn UnitTest ++ source code and UnitTest ++ test code. The test code of UnitTest ++ is well written. You can learn about the functions of UnitTest ++ and the writing methods of test cases.
