Golang Tips & Tricks #6 - the _test package

Testing is one of the hardest stuff in programming. Today trick will help you organize your tests and the production code.

Let’s assume you have a package called orders. When you want to separate the package for tests from the production code you can create a new folder and write tests there. It will work but there’s a more clearer way - put your tests to the folder with you package but suffix the package’s name in tests with _test.

order.go # package orders
order_test.go #package orders_test

I use this approach a lot and it helps to keep both prod and test code together but can can test the production code like from an external package. I hope you’ll find it useful.
