-After [building](https://github.com/likle/cwalk/wiki/Building) ``cwalk`` you can run tests to ensure everything runs fine. In order to do that, make sure you are in the build folder and then use either CTest or the native test program.
-
-## Using CTest
-To run CTest run the following in the build folder:
-```bash
-make test
-```
-
-That's it!
-
-## Using the native test program
-CTest is slightly slower than the native test program since it starts a process for each test.
-If you want to run the native test program you can do so by running the following in the build folder:
 ```bash
 ./cwalktest
 ```
 
+That's it!
+
 You can even specify which tests to execute by optionally specifying the category and test name:
 ```bash
 # ./cwalktest [category] [test]
