Crate gix_testtools 

Utilities for testing gitoxide crates, many of which might be useful for testing programs that use git in general.

Environment Variables

GIX_TEST_FIXTURE_HASH

Set this variable to control which hash function is used when creating or loading test fixtures. Valid values are the names of hash functions supported by gix_hash::Kind (e.g., sha1, sha256). If not set, the default hash function via gix_hash::Kind::default() is used.

Feature Flags

• worktree-exclusions (enabled by default) — Use the current repository’s ignore rules to decide if generated fixture archives should be written.
• xz — Use instead of plain tar files, compress these to produce tar.xz files instead. This is useful if archives are uploaded into git-lfs, which doesn’t have built-in compression and metering counts towards uncompressed bytes transferred.

Re-exports

Structs

AutoRevertToPreviousCWD

A utility to set the current working dir to the given value, on drop.

Env

A utility to set and unset environment variables, while restoring or removing them on drop.

GitDaemon

A wrapper for a running git-daemon which is stopped automatically on drop.

Enums

Creation

Define how scripted_fixture_writable_with_args() and rust_fixture_writable() produces the writable copy.

FixtureState

Indicates the state of a fixture when a closure is called.

Statics

GIT_VERSION

The major, minor and patch level of the git version on the system.

Functions

apply_git_config_by_environment

Apply command-scoped Git config to cmd, and return it.

bash_program

Get the path attempted as a bash interpreter, for fixture scripts having no #! we can use.

build_example_for_test

Build example from package and copy the executable to this test process’ temporary target directory.

copy_recursively_into_existing_dir

A utility to copy the entire contents of src_dir into dst_dir.

fixture_bytes

Load the fixture from <crate-root>/tests/fixtures/<path> and return its data, or panic.

fixture_path

Return the path to the <crate-root>/tests/fixtures/<path> directory.

git

Run git in current_dir with shell-like whitespace-separated arguments, returning stdout as UTF-8.

invoke_bash

Run script with bash_program() in cwd.

normalize_debug_snapshot

Normalize debug-formatted value so one snapshot can be reused for SHA-1 and SHA-256 fixtures.

normalize_hashes

Normalize 40- and 64-character hexadecimal object IDs in input.

object_hash

Like object_hash_from_env(), but returns the default hash if GIX_TEST_FIXTURE_HASH is not set.

object_hash_from_env

Returns the hash function that is used when creating or loading test fixtures.

run_git

Run git in working_dir with all provided args.

rust_fixture_read_only

Execute a Rust closure in a directory, returning a read-only fixture path.

rust_fixture_writable

Execute a Rust closure in a directory, returning a writable temporary directory.

scripted_fixture_read_only

Run the executable at script_name, like make_repo.sh or my_setup.py to produce a read-only directory to which the path is returned.

scripted_fixture_read_only_needs_archive

Like scripted_fixture_read_only(), but uses a matching existing archive even if GIX_TEST_IGNORE_ARCHIVES is set.

scripted_fixture_read_only_with_args

Like scripted_fixture_read_only(), but passes args to script_name.

scripted_fixture_read_only_with_args_single_archive

Like scripted_fixture_read_only()], but passes args to script_name.

scripted_fixture_read_only_with_args_single_archive_with_post

Like scripted_fixture_read_only_with_args_single_archive, but runs a Rust closure after the script completes.

scripted_fixture_read_only_with_args_with_post

Like scripted_fixture_read_only_with_args, but runs a Rust closure after the script completes.

scripted_fixture_read_only_with_post

Like scripted_fixture_read_only, but runs a Rust closure after the script completes.

scripted_fixture_writable

Run the executable at script_name, like make_repo.sh to produce a writable directory to which the tempdir is returned. It will be removed automatically, courtesy of tempfile::TempDir.

scripted_fixture_writable_with_args

Like scripted_fixture_writable(), but passes args to script_name while providing control over the way files are created with mode.

scripted_fixture_writable_with_args_single_archive

Like scripted_fixture_writable(), but passes args to script_name while providing control over the way files are created with mode.

scripted_fixture_writable_with_args_single_archive_with_post

Like scripted_fixture_writable_with_args_single_archive, but runs a Rust closure after the script completes.

scripted_fixture_writable_with_args_with_post

Like scripted_fixture_writable_with_args, but runs a Rust closure after the script completes.

scripted_fixture_writable_with_post

Like scripted_fixture_writable, but runs a Rust closure after the script completes.

set_current_dir

Set the current working dir to new_cwd and return a type that returns to the previous working dir on drop.

should_skip_as_git_version_is_smaller_than

Returns true if the given major, minor and patch is smaller than the actual git version on the system to facilitate skipping a test on the caller. Will never return true on CI which is expected to have a recent enough git version.

size_ok

Check data structure size, comparing strictly on 64-bit targets.

spawn_git_daemon

Spawn a git daemon to host all repositories at or below working_dir.

umaskUnix

Get the umask in a way that is safe, but may be too slow for use outside of tests.

Type Aliases

PostResult

A result type for post-processing closures in *_with_post fixture functions.

Result

A result type to allow using the try operator ? in unit tests.
