title: Integration Testing Approach for Code C/C++
body: <p>I have seen this <a href="https://stackoverflow.com/questions/1439172/testing-code-in-c-c">post</a> about Unit Testing for C/C++. I have heard that gtest can be used for Integration Testing. What is the best approach to do Integration Tests? I am afraid that this could replicate Unit/System tests so I am not sure what test technique should I use for C embedded systems.</p>
