TestData contains common test data like binary files

Functions

func AssertDiffContains 

func AssertDiffContains(t *testing.T, diff string, want ...string)

AssertDiffContains verifies that the given diff contains all expected strings. It calls t.Helper() to ensure accurate stack traces and fails the test if any expected string is missing.

func AssertDiffNotContains 

func AssertDiffNotContains(t *testing.T, diff string, unwanted ...string)

AssertDiffNotContains verifies that the given diff does not contain any unwanted strings. It calls t.Helper() to ensure accurate stack traces and fails the test if any unwanted string is found.

func CreateAndCommitFile 

func CreateAndCommitFile(t *testing.T, dir string, repo *git.Repository, filename, content, message string)

CreateAndCommitFile creates a file with the given content and commits it (legacy function for backward compatibility)

func CreateLargeFileWithManyHunks 

func CreateLargeFileWithManyHunks(t *testing.T, tmpDir string, repo *git.Repository)

func CreateTestRepo 

func CreateTestRepo(t *testing.T, prefix string) (string, *git.Repository, func())

CreateTestRepo creates a temporary directory with an initialized git repository (legacy function for backward compatibility)

func GenerateFunction 

func GenerateFunction(index int, version string) string

GenerateFunction generates a function with the given index and version

func RunCommand 

func RunCommand(t *testing.T, dir string, command string, args ...string) (string, error)

RunCommand executes a command in the specified directory (legacy function for backward compatibility)

func SetupTestDir 

func SetupTestDir(t *testing.T, dir string) func()

SetupTestDir changes to the test directory and returns a cleanup function (legacy function for backward compatibility)
