Documentation about unit testing
It would be great to have some documentation about how to test modules using closure-library, having some examples.
Hey, sorry for the delayed response! Do you mean specifically issues with modules (e.g. mocking out modules), or just unit testing in general (e.g. how to use junit / assertions / mocks)?
The tests accompanying the implementation for mocks and assertions (in good.labs.mock and goog.labs.testing, for example) also serve as good clues on how to use the utilities to mock and use assertions.
We're more or less moving off of these libraries and encouraging the use of other testing frameworks. If somebody wants to contribute documentation, it would be welcome, but it's pretty low priority for us.
