Overview

Mock git repository for fast unit tests without subprocess calls Provides a temp directory with files but no actual git init Use this for testing code that reads files but doesn’t need real git commands

Examples:

repo = MockGitRepo.new
repo.add_file("secret.txt", "TOKEN=ghp_abc123")
repo.add_commit("abc1234", message: "Add secret")
# Test code that examines repo structure
repo.cleanup

Constructor Details

#initialize {|self| ... } ⇒ MockGitRepo

Create a mock git repository

Examples:

Block initializer for concise setup

repo = MockGitRepo.new do |r|
  r.add_file("secret.txt", "TOKEN=abc123")
  r.add_commit("abc1234", message: "Add secret")
end

Yields:

  • (self) —

    Optionally yields self for one-line setup patterns

def initialize
  @path = Dir.mktmpdir("ace-mock-git-repo")
  @commits = []
  @files = {}
  # Create a fake .git directory to pass validation checks
  # This is much faster than running `git init` (~150ms savings)
  FileUtils.mkdir_p(File.join(@path, ".git"))
