Spot Coverage Gaps Using the Gutter
Let the IDE help you spot coverage gaps in your testing.
GoLand offers a builtin feature to allow you to run the tests in your project and display the coverage in a tool window as a summary for a package (folder) and file, and for each file, next to each line in the file.
How to use: Launch the test with Coverage support and then use the Coverage tool window to navigate to your packages/files and see their coverage.
