💼 This rule is enabled in the ✅ `recommended` [config](https://github.com/avajs/eslint-plugin-ava#recommended-config).

🔧 This rule is automatically fixable by the [`--fix` CLI option](https://eslint.org/docs/latest/user-guide/command-line-interface#--fix).

The `deepEqual` and `notDeepEqual` assertions are unnecessary when comparing primitives. Use `is` or `not` instead.

## Examples

```js
// ❌
t.deepEqual(expression, 'foo');
t.deepEqual(expression, 1);
t.deepEqual(expression, `foo${bar}`);
t.deepEqual(expression, null);
t.deepEqual(expression, undefined);
t.notDeepEqual(expression, undefined);

// ✅
t.is(expression, 'foo');
t.deepEqual(expression, otherExpression);
t.deepEqual(expression, {});
t.deepEqual(expression, []);
t.notDeepEqual(expression, []);
```
