Pull request overview
This PR adds new table-driven tests for the cmd package’s headers and license Cobra commands to improve overall repository test coverage and exercise common CLI flows (flag wiring, help text, and selected run paths).
Changes:
- Added
cmd/license_test.gocovering license year derivation, license command flags/help, and severallicenseexecution scenarios (including subprocess tests foros.Exitpaths). - Added
cmd/headers_test.gocovering headers command flags/help, header updating logic, LICENSE update logic, plan mode behavior, and header ignore patterns.

In cases the tests are running in parallel, can they read the dirty state of the global config ? If so, it can make the tests brittle

The test suite is intentionally written to run sequentially.
The functions - updateExistingHeaders, updateLicenseFile and Cobra command in headers.go file depend on the global conf pointer and os.Chdir for directory context. SInce it is a CLI tool with such constraints, only one command can run at a time in a single process.
You are right to point out that in case of parallel run, there can be dirty reads possible leading to race condition. The way I can think of achieving success even while running parallel tests is by refactoring the existing production code.
For the current implementation, no parallel calls are present and none should be added as well.
