Now that you have read the googletest Primer and learned how to write tests using googletest, it's time to learn some new tricks. Background. JUnit ist ein kleines, mächtiges Java-Framework zum Schreiben und Ausführen automatischer Unit Tests. These tests are much slower to run and harder to debug, so it is recommended to use GTest instead when possible. In other words, unit testing ensures that the individual parts of a program work, while integration testing verifies that the parts work together. Since unit testing requires that your code be easily testable, it means that your code must support this particular type of evaluation. CUnit is a lightweight system for writing, administering, and running unit tests in C. It provides C programmers a basic testing functionality with a flexible variety of user interfaces. I try to keep it simple in this guide. Let's say we have a C file that we want to test named DumbExample.c. Compile all three and link them together.
