A simple assertion library that you probably shouldn't use.

## Quickstart

Package `expect` contains various test assertion helpers.

```go

func TestOpenFile(t *testing.T) {

        f, err := os.Open("notfound")

        expect.Nil(err)

        err = f.Close()

        expect.True(err == nil)

}

```

`expect` helpers can be called from any function called from the main testing goroutine.

```bash

% go test

--- FAIL: TestOpenFile (0.00s)

    check_test.go:12: expected: , got: open notfound: no such file or directory

``` 

Consult the [documentation](https://godoc.org/github.com/pkg/expect) for more information.

## How does this work?

## No, seriously, how does this work?

`*testing.T` is recovered dynamically from the call stack. Read the [blog post](https://dave.cheney.net/2019/12/08/dynamically-scoped-variables-in-go).
