Question: How to call mock function if function in test calls them multiple times with different expectations inside

[pathakraul]

Hi, I am unable to find any way to test this scenario.

I have mocked version of read and write and a function func_to_test() which calls them multiple times.

void func_to_test()
{
    ret = read(addr1, &val1);
    ret = write(addr1, val1);

    ret = read(addr2, &val2);
    ret = write(addr2, &val2);

    .....
}

TEST()
{
         read_****();
         write_****();
         TEST_ASSERT_***(..., func_to_test())
}

In this case how can I call the mocked versions read_***() and write_***() before the TEST_ASSERT_** which calls my func_to_test such that they take affect with different values for different calls inside the test function. Or what is the right way to test this case

Thanks, Rahul

In your test, you may set up as many expectations as desired, in order... so in your instance, it would look like this:

TEST()
{
         read_ExpectAndReturn();
         write_ExpectAndReturn();
         read_ExpectAndReturn();
         write_ExpectAndReturn();
         TEST_ASSERT_***(..., func_to_test())
}

I suspect you'd also want to look into the return-thru-pointer plugin to handle the val1, and val2 returns in the read functions.
