test(git): Enhance Git parser tests with temporary repository setup

[aftersnow]

Added a temporary Git repository setup in the test for the Git parser. This includes initializing a repository, creating a remote, adding a test file, and committing it before parsing. Updated assertions to verify the correct URL and commit SHA from the newly created repository.

Summary of Changes

Hello @aftersnow, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the reliability and maintainability of the Git parser tests. By transitioning from a static test fixture to a dynamically generated Git repository, the tests now more accurately simulate real-world Git environments, ensuring that the parser correctly extracts information from various repository states. This change reduces the potential for test flakiness and improves the overall quality of the testing suite.

Highlights

• Dynamic Test Repository Creation: The Git parser test now dynamically creates a temporary Git repository for each test run, ensuring isolated and reproducible test environments.
• Realistic Git Operations: The temporary repository is initialized with a remote, a file is added, and a commit is made, simulating a more realistic Git workflow for testing.
• Enhanced Assertions: Test assertions have been updated to verify the URL and commit SHA against the dynamically generated values from the temporary repository, improving test accuracy.

Changelog

• pkg/source/git_test.go
  • Introduced new imports for "os", "path/filepath", "time", "gogit", "config", "object", and "require" to support Git repository manipulation.
  • Refactored TestGit to set up a temporary directory and initialize a new Git repository within it.
  • Programmatically created a remote named "origin" with a predefined URL.
  • Added a README.md file to the temporary repository and performed an initial commit.
  • Modified the parser.Parse call to target the newly created temporary repository.
  • Updated assertions to validate the parsed URL and commit SHA against the values generated during the temporary repository setup.

Code Review

This pull request significantly improves the Git parser test by replacing a static test data directory with a dynamically created temporary Git repository. This change makes the test suite more robust and self-contained. The implementation is clean and follows good practices for testing in Go. I have one suggestion to further improve the test's determinism.

Since we used temp for testing, so we can remove the original testdata/git-repo directory?
