insta 1.24.1

A snapshot testing library for Rust
Documentation
# Changelog

All notable changes to insta and cargo-insta are documented here.

## 1.24.1

- Fix non working `--include-hidden` flag (#331)
- Fix incorrect mapping of `review.include_ignored` (#330) 

## 1.24.0

- Added an insta tool config (`.config/insta.yaml`) to change the
  behavior of insta and cargo-insta. (#322)
- Renamed `--no-ignore` to `--include-ignored`.
- Added `--include-hidden` to instruct insta to also walk into
  hidden paths.
- Added new `--unreferenced` option to `cargo-insta test` which allows
  fine tuning of what should happen with unreferenced files.  It's now
  possible to ignore (default), warn, reject or delete unreferenced
  snapshots. (#328)
- Resolved an error message about doc tests when using nextest with
  test targeting. (#317)

## 1.23.0

- Add a hint if snapshots might be skipped. (#314)
- Avoid extra newline in YAML snapshots. (#311)

## 1.22.0

- Added support for rendering some invisibles in diffs.  This now also
  should make sure that ANSI sequences in strings are no longer screwing
  up the terminal output. (#308)
- Prevent inline snapshots to be used in loops. (#307)
- Support the `--target` option to `cargo insta test`. (#309)
- Globbing now adds directories as disambiguators into the snapshot
  suffixes. This allows patterns such as `foo/*/*.txt` without
  creating conflicts. (#310)

## 1.21.2

- Added missing parameters to `cargo insta test`. (#305)
- Fixed a sorting issue in hash maps for compound keys. (#304)

## 1.21.1

- Fix incorrect handling of extra args to `cargo insta test`.

## 1.21.0

- Fixed an issue that broke support for older rust versions. (#292)
- Added `cargo insta show` command to render a snapshot.
- Added support for compact JSON snapshots. (#288)

## 1.20.0

- `cargo insta` now supports nextest as test runner. (#285)
- The `glob!` macro now defers failures by default. (#284)

## 1.19.1

- Added support for numeric keys in JSON which regressed in 0.18.0. (#281)

## 1.19.0

- Removed `backtrace` feature.
- Removed `serialization` feature.
- `assert_json_snapshot!` and `assert_yaml_snapshot!` now require
  the `json` and `yaml` feature respectively.
- Doctests now emit a warning that inline snapshot updating is
  not supported (#272)
- Added support for `INSTA_GLOB_FILTER` to skip over tests expanded
  from a glob. (#274)

## 1.18.2

- Avoid the use of `#[allow(unused)]` in the macro. (#271)

## 1.18.1

- Fixed a regression in the JSON serialization format with newtypes and
  tuple variants. (#270)

## 1.18.0

- `Settings::bind` now can return a result.
- Expose the drop guard type of `bind_to_scope`.
- The `serde` dependency is now optional. While still enabled by default
  users need to opt into `yaml` and `json` features explicitly to regain
  support for it. To avoid the default `serde` dependency the default
  features just need to be disabled. (#255)
- Deprecated unused `serialization` features.
- Deprecated unused `backtrace` feature.
- Removed deprecated `Settings::bind_to_thread`.

**Breaking Changes / Upgrading:** If you are upgrading to serde 1.18.0 you will
receive deprecating warnings if you are using the `assert_yaml_snapshot!` and
`assert_json_snapshot!` macros. These macros will continue to function in the
future but they will require explicit opting into the `yaml` and `json` features.
To silence the warning add them to your `insta` dependency. Additionally the
`backtrace` feature was deprecated. It is no longer needed so just remove it.

## 1.17.2

- Remove an accidentaly debug print output.

## 1.17.1

- Added support for nextest. (#242)
- Resolved an issue where inline snapshot tests in doctests refused to
  work. (#252)

## 1.17.0

- Fixed an issue in `cargo-insta` where sometimes accepting inline snapshots
  would crash with an out of bounds panic.
- Added new `filters` feature. (#245)
- Disallow unnamed snapshots in doctests. (#246)
- `with_settings!` macro now inherits the former settings rather than resetting. (#249)
- Added support for `Settings::bind_to_scope` and deprecated
  `Settings::bind_to_thread`. (#250)
- Added support for `minimal-versions` builds.

## 1.16.0

- Added `--no-quiet`/`-Q` flag to `cargo insta test` to suppress the
  quiet flag. This works around limitations with custom test harnesses
  such as cucumber.
- Update RON to 0.7.1.
- Improved ergonomics around `with_settings!`. It's now a perfect match to
  the settings object's setter methods.
- Added `description` and `info` to snapshots. (#239)
- Added `omit_expression` setting. (#239)
- Added improved support for running insta from doctests. (#243)

## 1.15.0

- Bump minimum version of Rust to 1.56.1. This was done because the used
  serde-yaml dependency no longer supports older versions of Rust.

## 1.14.1

- Update uuid crate to 1.0.0. (#228)
- Use inline block format also for strings of form `"foo\n"`. (#225)

## 1.14.0

- Fixed a bug that caused insta to panic if inline snapshot assertions
  moved since the time of the snapshot creation. (#220)
- `cargo insta test` now returns non zero status code when snapshots
  are left for review. (#222)
- Assertion failures now mention `cargo insta test`. (#223)

## 1.13.0

- Fixed a bug where an extra newline was emitted following the snapshot header.
- `assertion_line` is no longer retained in snapshots. (#218)

## 1.12.0

- Add support for sorting redactions (`sorted_redaction` and `Settings::sort_selector`). (#212)
- Changed snapshot name detection to no longer use thread names but function names. (#213)

**Upgrade Notes:**

Insta used to detect the current test name by using the current thread name. This
appeared to work well but unfortunately ran into various limitations. In particular
in some cases the thread name was truncated, missing or did not point to the current
test name. To better support different platforms and situations insta now uses the
function name instead.

This however changes behavior. In particular if you are using a helper function to
assert, a different snapshot name will now be used. You can work around this issue
by using a helper macro instead or to explicitly pass a snapshot name in such
situations.

## 1.11.0

- Trim down some unnecessary dependencies and switch to `once_cell`. (#208)

## 1.10.0

- Update internal dependencies for console and ron.

## 1.9.0

  on `test` when deleting unreferenced snapshots. (#201)

## 1.8.0

- Added the ability to redact into a key. (#192)
- Insta now memorizes assertion line numbers in snapshots. While these
  will quickly be old, they are often useful when reviewing snapshots
  immediately after creation with `cargo-insta`. (#191)

## 1.7.2

- Fixed an issue where selectors could not start with underscore. (#189)
- Allow passing arguments to `cargo test`. (#183)
- Avoid the use of `Box::leak`. (#185)
- When `INSTA_WORKSPACE_ROOT` is set, the value is used as the manifest
  directory rather than whatever `CARGO_MANIFEST_DIR` was set to at compile
  time. (#180)

To upgrade to the new insta macros and snapshot formats you can use
[`fastmod`](https://crates.io/crates/fastmod) and `cargo-insta` together:

    $ cargo install fastmod
    $ cargo install cargo-insta
    $ fastmod '\bassert_([a-z]+_snapshot)_matches!' 'assert_${`}!' -e rs --accept-all
    $ cargo insta test --all --force-update-snapshots --accept
