# Qilan concept
## Mocks
### Creating a mock from a class
```js
class Dog {
bark(type) { /* ... */ }
async woof() { /* ... */ }
}
const dog = mock(Dog);
```
## Spies
### Creating a spy
```js
const bark = spy();
const woof = when().resolve();
const meow = when(() => spy()).do('m-m-meow');
const purr = when(() => spy('purr?')).return('purr!');
```
### Spying on all methods & properties
```js
spy(dog);
```
## Custom behavior
### Simple
```js
when(() => dog.name).return('Cooper');
when(() => dog.bark()).do(() => console.log('bark!'));
```
### Multiple calls
```js
when(() => dog.name).return('Cooper', 'Baxter');
when(() => dog.bark()).do(
() => console.log('odd bark!'),
() => console.log('even bark!'),
);
console.log(dog.name, dog.name, dog.name); // Cooper Baxter Cooper
console.log(dog.bark(), dog.bark(), dog.bark()); // odd bark! even bark! odd bark!
```
```js
when(() => dog.name).returnOnce('Cooper', 'Baxter');
when(() => dog.bark()).doOnce(
() => console.log('first bark!'),
() => console.log('second bark!'),
);
console.log(dog.name, dog.name, dog.name); // Cooper Baxter undefined
console.log(dog.bark(), dog.bark(), dog.bark()); // first bark! second bark! undefined
```
### Arguments
```js
when(() => cat.meow()).do(type => 'meow');
when(() => cat.meow(anyArgs())).do(type => 'm-m-meow');
when(() => dog.bark(any(String))).do(type => `${type} bark!`);
when(() => dog.bark(any(Number))).do(count => `bark #${count}!`);
```
## Expectations
### Equality assertion
```js
same(dog.breed, 'Doge');
equal(dog.age, any(Number));
```
### Call expectations
```js
called(() => dog.bark(anyArgs()));
calledOnce(() => dog.woof());
calledTimes(5, () => cat.meow(true));
notCalled(() => cat.purr(any(String), any()));
```
