Here’s a quick tip on how to skip long running tests in Go. In your test function that you want to skip, add a t.Short() boolean check. For example: func TestLongRunning(t *testing.T) { if t.Short() { t.Skip("skip long running test") } // tests that will take a while to run ... } Then when you run go test, simply provide a -short flag to skip the test. For example:

One thing I miss when switching from VS Code to GoLand is the ability to auto-format the code with go fmt when saving the files. You need to navigate to Tools > Go Tools > Go Fmt Project to run it, or use the keyboard shortcut which is ⌥⇧⌘P. Still, this is something that you can easily forget to run every single time. Luckily, GoLand have built in file watchers that you can use to run go fmt every time there’s a file changes.

I started using GoLand yesterday after hearing good things about it from my friends who is doing Go development. When I try to use the GoLand’s debugger, I got the following error; could not launch process: debugserver or lldb-server not found: install XCode’s command line tools or lldb-server How Do I Fix It?

Testing is about verifying the behavior of a system. If the system behaves differently when under test, then how can we be certain that the production code actually works? The production code should not contain any conditional statements of the if testing then sort.

Sometimes when debugging on Xcode with LLDB’s p or po, it will throw a syntax error at you and you might be wondering out why? You checked for any typos but everything seems to be correct. So what gives? Well, that’s because you might be using it in the wrong context. Here’s a quick rundown: When you stop in Objective-C code using breakpoint, LLDB will use Objective-C debugging context.
