Cmocka - should we all be creating one executable per test for isolating static variables?

Yes, if you have a static variable in the tested object, you need to compile separated tests if they expect a "fresh" test object.

I would do this anyway, each test in a separated executable, since you have a Singleton in your test object.

This is a fine example why the Singleton pattern is an anti-pattern today. It is hard to test.

ANSWER

You need to add the declaration for the foo function. Currently foo(1, 1, 1, bar); will use an implicit declaration of int foo(). Implicit declarations are invalid since C99 so you should be able to turn on more warnings to catch this (-Wimplicit-function-declaration -Werror).

The implicitly declared function takes the arguments you've given it (which will actually match __wrap_foo, given that int32_t is a typedef for int) and will return int, not ExampleStruct, so your program will have Undefined Behavior.

According to your test, it seams that function you are testing is led_status_toggel. If that is the case, you should not mock it. You should just remove will_return(led_status_toggel,SET);, since your led_status_toggel is probably something like this (You dind't share it so I don't know exactly):

I want to use libssh library in Qt and my os is ubuntu 18.04 .

file INSTALL cannot copy file
"/home/heydari.f/libssh-mirror/build/libssh.pc" to
"/usr/local/lib/pkgconfig/libssh.pc"

This is a permissions issue. Use sudo make install to solve this. sudo gives root privileges to a command. Use it carefully.

** error: undefined reference to 'ssh_session_is_known_server'**

undefined reference usually means you are trying to access something, in this case a function, which is not found. This function belongs to libssh, so it means that either you don't have libssh-dev installed or you are giving the path to the library incorrectly. Since the latter is highly unlikely, i am going to assume libssh is missing. On Ubuntu you can install it using following command:

The include_directories() command only affects header search paths (stuff that is used through #include). It has no effect on library search paths.

Since you know the full path of the library, you should just be linking directly against said full path:

Cmocka unit testing with C: mocking nested function calls

Asked 2020-Mar-29 at 07:20

So, toy program that duplicates the issues I am having using cmocka for developing unit tests for existing code. The issue is a nested function call does not mock, which makes the unit test dependent on the nested function call performing properly. Please note, that "mockable_static" define was used as the original code has static functions that exist as "internal function calls", but for purposes of unit tests, these are open to external calls. (See stackoverflow post where this idea came from)

Without further ado, here is the code:

func.h:

ANSWER

Answered 2020-Feb-25 at 23:45

Alright, so there are a few different avenues to solve this problem. I am posting the solution so someone else can see this.

Solution #1: separate nested function calls into separate .c files. IE- func.c contains foo() and (newfile)bar.c contains bar(). This allows the GCC --wrap=bar to work within func.c as it needs to link against another file.

Solution #2: build separate tests for testing bar and foo. Use the following line in func.c to make bar "weak"
