## Requirements

* [Coverage Gutters](https://github.com/ryanluker/vscode-coverage-gutters): vscode extension to display language-agnostic coverage from lcov reports
* [Reflex](https://github.com/cespare/reflex): to watch files and perform actions on change
* [gcov2lcov](https://github.com/jandelgado/gcov2lcov): to convert from Go's coverage report format to lcov
* [gotest](https://github.com/rakyll/gotest): optional, you could just use `go test`

## Usage

The path to what you want to test is required.

The rest is optional, but you can pass whatever you'd pass to `go test`.

```sh
# Watch and test all packages
retest ./...

# Watch and test a specific path
retest ./tokenizer

# Watch and test a subset of tests
retest -run=TestSomething/Foo ./tokenizer
```
