How to install and use Cppunit

[KennedII]

Hi all,

I want to use open-source unit testing tool. I found that the very popular tool CppUnit which contains a number of classes, contribute to white-box testing and regression test suite to create your own. I want to know that some of the more useful CppUnit features, such as TestCase, TestSuite, TestFixture, TestRunner and supporting macros. Please help. Thanks in advance.

you need to run and configure Command, and then run the make install. Note that for cygwin and other platforms, this process may not be successfully completed, it must pass INSTALL. If the installation is successful, should be the installation path (CPPUNIT_HOME). To see CppUnit the include and lib folders.
CppUnit installation directory structure are looks as

[arpan @ tintin] echo $ CPPUNIT_HOME
/ home / arpan / ibm / cppUnit
[arpan @ tintin] ls $ CPPUNIT_HOME

To compile use the CppUnit test, we must build the source code:

g + + <C/C++ file>-I $ CPPUNIT_HOME / include-L $ CPPUNIT_HOME / lib-lcppunit

Note that if you are using a shared library version of CppUnit, you may need to use -Ldl Option to compile the source code. After the installation, may need to modify the UNIX environment variable LD_LIBRARY_PATH to reflect libcppunit.

You need to create a basic test using the CppUnit. CppUnit with a set of pre-defined classes, you can easily use them to design tests. In order to maintain continuity, first take a look in this code:

# ifndef _MYSTRING
# define _MYSTRING
class mystring (
  char * buffer;
  int length;
  public:
    void setbuffer (char * s) (buffer = s; length = strlen (s);)
    char & operator [] (const int index) (return buffer [index];)
    int size () (return length;)
 );
# endif

The string associated with the typical inspection include checking whether the empty string the length of the 0 and interviews that go beyond the index is causing the error message / exception. Check and reply.

Check th ebelow code:

# include <cppunit/TestCase.h>
# include <cppunit/ui/text/TextTestRunner.h>
class mystringTest: public CppUnit:: TestCase (
public:
  void runTest () (
    mystring s;
    CPPUNIT_ASSERT_MESSAGE ( "String Length Non-Zero", s.size ()! = 0);
  )
);
int main ()
(
  mystringTest test;
  CppUnit:: TextTestRunner runner;
  runner.addTest (& test);
  runner.run ();
  return 0;
)

To create a unit test for the string class, you need to create CppUnit:: TestCase Class, subclass, and override runTest Method. Defines the test itself, the instantiation TextTestRunner Class, this is a controller class, you must add the test (vide addTest Methods). Check and reply.

Developers will continue to add features, these features also need to be tested. In the same test suite in the continuous addition of tests will gradually lead to confusion, but also easy as the first test of the revised amendment increasing the loss. Fortunately, CppUnit provides a useful CPPUNIT_TEST_SUB_SUITE Macro, you can use it to expand the existing test suite.Listing 13 Use this macro. Note that the new class mystringTestNew from the front myStringTest Derived class. CPPUNIT_TEST_SUB_SUITE Macro two parameters is the new class and its superclass. On the client, only to register this new class, two classes do not need to register. Other parts of grammar and syntax to create the same test suite. All the best.
