Generics

Intent action to convert empty interface to `any`

GoLand's new check can report empty interface usage as a type or type constraint.

Another intent action is to interface{} replace with any. From the intent action's popup, you can replace all empty interfaces in the file.

Quick fix for removing type parameters with empty parameter lists

Type parameters with empty parameter lists are now reported as errors. We added a quick fix to remove it.

Checking for unused type parameters

We've added a new inspection that reports unused type parameters. They will be greyed out and when you hover over them you will see a warning.

Check for union of interface and method

The IDE now reports an error if you try to use an interface with a method in a union.

Fuzzing

run fuzz tests

You can now run fuzz tests from GoLand. If you click on the green triangle icon in the space next to the fuzz test, you will see different options for running the test. If the test fails, the failed seed corpus entry will be written to a file and placed in testdata the package directory of the folder.

The path to this file will also appear in the console as a clickable link. If you click this link, the file will open in the IDE with a green triangle icon at the top of the file. Clicking this icon will run go test and display the failed seed corpus entries.

From GoLand you can also run fuzz tests like normal unit tests

A quick fix for changing the Go SDK

In GoLand, if a Go SDK is configured that does not support fuzzing, the run button will no longer appear in the gutter. We've added a quick fix that changes the Go SDK when the current Go SDK doesn't support fuzzing.
