I'm trying to use check unit testing framework for my C application. But I can't use the debugger (gdb) with it because of two points:
first, check use some complex macros (START_TEST
and END_TEST
) and the debugger has trouble to put a breakpoint in my code between these two macros (in fact, I can put a software breakpoint but It is never seen by gdb)
second, check define some sort of exceptions by redefining behavior of interruption. Hence, when I try to put a hardware breakpoint, the test failed and exit because check consider the hardware breakpoint as a failure of my test.
Does anyone has already met this problem and has a solution?
Debug and analyze unit tests with Test ExplorerYou can use Test Explorer to start a debugging session for your tests. Stepping through your code with the Visual Studio debugger seamlessly takes you back and forth between the unit tests and the project under test.
A unit test typically features three different phases: Arrange, Act, and Assert (sometimes referred to as AAA). For a unit test to be successful, the resulting behavior in all three phases must be in line with expectations.
Set a break point within the text of the test, use the menu option, and you should be able to immediately debug your test. A NUnit test is defined as a method that is public , not static , with no parameters, has a return type of void , and has the Test attribute.
Look at the no-fork mode:
Check normally forks to create a separate address space. This allows a signal or early exit to be caught and reported, rather than taking down the entire test program, and is normally very useful. However, when you are trying to debug why the segmentation fault or other program error occurred, forking makes it difficult to use debugging tools.
Actually, you CAN use fork-mode too.
gdb has two interesting options related to fork behaviour:
- detach-on-fork
(set this to false)
- follow-on-fork
(either parent or child; I always take child)
This will make gdb follow the child process.
When the child process has ended, you have to manually switch back to the parent process by using the inferior
command.
