## Installation

```bash
npm install @olton/easytest -D
```

## Usage

To use `EasyTest` you don't need to import `it`, `test` or `describe` in your test file.
Create a test file with `*.test.js` or `*.test.ts` extension (for example).
You can use both of them in the same project.

```javascript
function hello() {
    return "Hello"
}

describe(`Common tests suite`, () => {
    it(`says hello`, () => {
        return expect(hello()).toBe("Hello")
    })
})

test(`Bad test 2 !== 1`, () => {
    return expect(2).toBe(1)
})

```

### Async tests
```javascript
async function fetchData() {
    return new Promise((resolve) => {
        setTimeout(() => {
            resolve("Data received");
        }, 1000);
    });
}

describe('Async function tests', async () => {
    it('should return data after 1 second', async () => {
        const data = await fetchData();
        return expect(data).toBe("Bad Data");
    });
});
```

Update `package.json` to run tests with `easytest` command.
```json
{
    "scripts": {
        "test": "easytest"
    }
}
```

### Functions
- `describe` - create test suite
- `it` - create a test case
- `test` - create simple test
- `expect` - create assertion
- `beforeEach` - run before each test case
- `afterEach` - run after each test case
- `beforeAll` - run before all test cases
- `afterAll` - run after all test cases
- `mock` - create mock function

### Matchers
EasyTest contains a big set of built-in matchers:

- A simple comparison
- A strong comparison
- Type checking
- Number checking
- String checking
- Array checking
- Object checking
- Color checking
- IP, Email, Url checking
- JSON, XML checking
- Date, RegExp, Symbol checking

- and more...


### TypeScript
To use `EasyTest` with TypeScript you need to install `tsx` package.
```bash
npm install -D tsx cross-env
```
and then 
```json
{
    "scripts": {
        "test": "cross-env NODE_OPTIONS=\"--import tsx\" easytest"
    }
}
```
