In Section 1.5 the following sentence appears:

"Both JUnit and TestNG are written in Java as well."

This was confusing to me because I thought it meant that the JUnit and TestNG frameworks themselves are written in Java, which is a perfectly legitimate thing to say. Reading further it became clear that what the sentence means is that tests are written in Java. I think it would be clearer if the original sentence stated that explicitly:

"Unit tests in both JUnit and TestNG are written in Java as well."

Hello

You are perfectly right. I will fix this sentence as you suggested.
