Experiments

Pre-release versions of vscode-go include experimental features. These features may be individually enabled or disabled via the setting go.experiments.

Test explorer

Go Companion includes an experimental test explorer implementation based on gopls's test discovery. This requires gopls v0.17.0 or newer. If Go Companion is present and vscode-go is a pre-release version, vscode-go will prefer Go Companion's test explorer, disabling its own, unless the experiment is set to off. The experimental test explorer provides more robust test discovery by using gopls, including static discovery of some subtests. It also implements:

• Ignore tests within files excluded by files.exclude or goExp.testExplorer.exclude.
• Disable automatic discovery of tests by setting goExp.testExplorer.discovery to "off".
• Control how tests are displayed with goExp.testExplorer.showFiles, goExp.testExplorer.nestPackages, and goExp.testExplorer.nestSubtests.
• Debugging a test updates its status in the test explorer.
• Support for continuous runs.
• Support for code coverage.
• Code lenses (hidden by default) that are integrated with the test explorer.
• Integrated viewer for pprof profiles.
