Hi, Xie Yihui,

I am new to testing, and I have looked into your package. I feel confused and hope you can help me.

I am not sure what exactly is your package doing. One function "assert()" combines two R built-in functions. The other function "test_pkg()" allows us not type ":::". I mean where is the testing part? Or is your package somewhat like a test framework? How does your package automatically run user-written test cases (not R CMD check) ?

I appreciate your help!
