There are a variety of C unit testing frameworks available however many of them are fairly complex and require the latest compiler technology. Some development requires the use of old compilers which makes it difficult to use some unit testing frameworks. In addition many unit testing frameworks assume the code being tested is an application or module that is targeted to the same platform that will ultimately execute the test. Because of this assumption many frameworks require the inclusion of standard C library headers in the code module being tested which may collide with the custom or incomplete implementation of the C library utilized by the code under test.
