# Detest

A [Deno](https://github.com/denoland/deno) Testing Library

> We don't just hate bugs, we detest them!

## Use

```typescript

import { describe, it, test, runTests} from "./detest/detest.ts"

describe("testing", () => {

  it("works", () => { 1 + 1 })"

  describe("describes can be nested", () => {

    test("1 + -1", () => expect(1 + (-1)).toBe(0)) 

    test("1 + -3", () => expect(1 + (-3)).toBe(-2)) 

  })

  describe("async testing", () => {

    it("is also possible", async () => {

      let value = await fetchValue()

      expect(value).toBe("found")

    })

  })

  describe("before(each)", () => {

    let setupValue

    let resets

    before(() => {

      setupValue = 12345

    })

    beforeEach(() => {

      resets = 0

    })

    it("should be 0", () => { 

      expect(resets).toBe(0)

      resets++

    })

    it("should still be 0", () => expect(resets).toBe(0))

  })

})

runTest()

```

### API

* `function describe(description: string, callback: () => void): void`

* `function it(description: string, callback: () => void | Promise): void`

* `function test`: Alias for `it`.

* `function before(callback: () => void): void`

* `function beforeEach(callback: () => void): void`

* `function expect(actual: any): DeferredExpectation`

* `class DeferredExpectation`

  * `toBe(expected: any)`

## Development

Run Tests

```bash

deno detest.test.ts

```

## Roadmap

* after/afterEach

* expand expectation library

* async before(Each)
