So far the Android stuff seems to cache ok, but not go, that didn’t seem to properly persist to cache even though the save cache step ran and the go install was successful. I attempted to do so along with caching for Android tooling being installed on Mac OS environment (Android SDK, NDK, platform tools). Open your hello_word again.Has anyone installed go on Mac OS build environment and then saved it to cache for future builds and restoring from cache at the start thereafter? Someone could ask, did the author forget something? How to run the go/golang program? Ok, if you need it. Now, you have your first TDD project, push it to GitHub. Run tests again ( go test) and you should see this: ok _/Users/marcin/GoglandProjects/hello_world 0.006s Summary ImplementationĬreate file hello_world.go which contains: package main hello_world_test.go:8: undefined: HelloWorldįAIL _/Users/marcin/GoglandProjects/hello_world In both cases, you should see something similar.

To run tests, you can use command line by typing go test in path with your project or using IDE by choosing option Run All. In go/golang each file with test scenarios must have suffix _test.

This approach has more pros than cons.Ĭreate file hello_world_test.go. In my last notes, I’ve often talked about Test Driven Development. What’s next? Nothing, you can run Gogland (IDE) and start writing code. First, what you have to do is to run that command: brew install go The process of installation is very easy. In my opinion, you shouldn’t waste time trying using “just” code editors like Sublime or Atom. Somewhere, we have to write our code and run tests.

You can read my previously note how to install brew before you start. brew is a small ruby script which allows you to install libraries with one command directly from command line.Therefore, we can assume that this language won’t be abandoned and learning it has a little more sense if you require something more than being hipster developer. But it is used by the biggest brands like Uber, Netflix, Google. The most important thing: it is still a young tool. Let’s start with explaining what go/golang is and why you should look at it if you are programming in any other language.
