The simplest way of creating a new test file in GoLand is by using a dedicated shortcut that you can invoke from your source code. In this case, the IDE creates a new test file and generates test code for this file, package, or function.
Generate test files
In the code editor, navigate toor press Alt+Insert.
Select what kind of a test you want to generate and press Enter. You can create test files for the following scopes:
Empty test file
Test for function
Tests for file
Tests for package
Navigate between tests and production code
In GoLand, you can jump between test classes and production code.
In the editor, place the caret at the test class or at the test subject in the source code and press Control+Shift+T (or ).
If there's only one test for this class, the IDE will navigate you to it right away. Otherwise, you will be prompted to select the necessary test from a popup or create a new test.
