As with any framework out there, as you learn Arquillian you are going to have a learning curve as you come up to speed on how it operates and some of its nuances. None of these should be considered blocking issues for you – you should research the errors as presented and try to remedy them.
Next, we're going to get more in depth over creating test cases. We'll review in more depth how to construct your Arquillian test cases and form them into test suites. In the first four chapters we've learned a bit about how Arquillian came to be, as well as being introduced to container-style testing. The remainder of the book focuses on the core testing functionality of Arquillian, eventually leading to information about Arquillian extensions.
