Details
Requires Git and Bash. Run in a disposable practice repository. The test setup below creates the starting files and commits. branch -m changes the local branch name without creating a new commit. The input setup creates a disposable practice repository with a fictional local author identity. Run these examples only in that repository.
Tested on Ubuntu 24.04.5 LTS · · git version 2.43.0 · git 1:2.43.0-1ubuntu7.3
Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Snippet process uid 65534 with a read-only root filesystem and temporary working files. Networking disabled. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
