Karma Unit Testing

I need someone with knowledge of Karma Unit Testing to write some tests. I was given 2 files and I am supposed to create a third that has all the various test cases. The first file is "navigation". This is the main html file that contains the code for a website. The second file "navigation directive" is supposed to help me created the Karma Unit Tests. The third file "navigation directive test" is what I have done so far. If it is wrong then please feel free to change it. Only apply for this freelance project if you have done Karma Unit Testing successfully in the past!!!
