# cargo-testdox

A Cargo subcommand to print your Rust test names as sentences.

## Installation

```sh

cargo install cargo-testdox

```

## Usage

In any Rust project with tests, run:

```sh

cargo testdox

```

![Animated demo](img/demo.gif)

`cargo-testdox` will first invoke `cargo test` to run your tests, with any extra arguments that you give it. It will then show the result for each test (passed, failed, or ignored), with the test name formatted as a sentence. That is, with underscores replaced by spaces.

For example, the following test:

```rust

#[test]

fn it_works() {}

```

will produce this output when run with `cargo-testdox`:

```

 ✔ it works

```

If the test were failing, it would produce:

```

 x it works

```

If the test were ignored, it would produce:

```

 ? it works

```

Doctests are ignored, since they can't currently be named (pending [RFC #3311](https://github.com/rust-lang/rfcs/pull/3311)).

### Function names with underscores

To avoid underscores in a snake-case function name from being replaced, put `_fn_` after the function name:

```rust

#[test]

fn print_hello_world_fn_prints_hello_world() {}

```

becomes:

```

✔ print_hello_world prints hello world

```

## Why

Because [test names should be sentences](https://bitfieldconsulting.com/posts/test-names).

Compare [`gotestdox`](https://github.com/bitfield/gotestdox), a similar tool for Go tests.
