I learned testing on the job. That said, I would never trust a learning channel like the one you describe. I've learned the hard way that people who consider themselves experts on unit testing tend to believe that more tests are always better, and have no idea of the impact of excessive unit tests on a codebase. So a channel like the one you describe is going to attract people whose opinions I'm suspicious of. Instead aim to be expert at developing software. Unit testing will prove to be an important component. But nothing about unit testing makes sense when separated from the development that you are attempting to accomplish. For a very enlightening example, consider http://ravimohan.blogspot.com/2007/04/learning-from-sudoku-solvers.html http://ravimohan.blogspot.com/2007/04/learning-from-sudoku-s... to compare someone who is an expert on unit testing (Ron Jeffries) with someone who is an expert on software development (Peter Norvig).
