Run Lint

Add this to your .vscode/tasks.json file to get the full linting output in your problems pane.

By default, the golangci-lint config includes --fast to avoid impacting your editing.

This ensures all tasks that a pre-commit check or CI check will run and provided in the problems panel.

Run Nicely Formatted Test Output

Tparse

While the testing extension is great, sometimes you might want to see a console summary. This task uses Tparse and provides a nicely formatted summary (including coverage numbers, cached tests, and more).

Install tparse with: go install github.com/mfridman/tparse@latest.

To run manually: GOTESTS='slow' go test ./... -v -cover -json | tparse -all
