### What it does

This rule enforces a maximum number of `expect()` calls in a single test.

### Why is this bad?

Tests with many different assertions are likely mixing multiple objectives.
It is generally better to have a single objective per test to ensure that when a test fails,
the problem is easy to identify.

### Examples

Examples of **incorrect** code for this rule:

```javascript
test("should not pass", () => {
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
});

it("should not pass", () => {
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
  expect(true).toBeDefined();
});
```

## Configuration

### max
