As someone who has bootstrapped themselves to a basic level of coding knowledge thanks to Google, I'll ask the potentially stupid question: How do I learn how to do unit testing? I know what it is but I have no idea how to go about it. Resources?
- eranation 14y agoWhat is your language? the answer can be rspec, junit, selenium, etc based on the language and framework. basically unit testing is on the function/class/module basis. you break your design into modules, each having a clear role, and make them plug into each other in a way that you can "mock" the "rest of the world" (e.g. other objects) and test only that part. to give an example, let's say you create a car, the unit test is to take a wheel, and spin it as if it's on the road, but without a car. take the lights, and plug them in as if they are in the car, take the engine and run it as if it's connected to the transmission, etc. in a car it's a bit more difficult, but in code, if your view needs a model, it doesn't matter if it was created from a database, a text file, or coded, as long as the interface fits.
- konradb 14y agoWhat language are you using? If it's Java I found 'Test Driven Development' by Kent Beck a great book if you want to 'get' unit testing and TDD. There's a gap before when the point of TDD 'clicks' and you see the 'why'; before that it can seem a huge bore. After that it can seem a bore too in some situations but you can see the benefits of it.
