# Suggest using `toBeNull()` (`prefer-to-be-null`)
## Deprecated
This rule has been deprecated in favor of [`prefer-to-be`](prefer-to-be.md).
In order to have a better failure message, `toBeNull()` should be used upon
asserting expectations on null value.
## Rule details
This rule triggers a warning if `toBe()`, `toEqual()` or `toStrictEqual()` is
used to assert a null value.
```js
expect(null).toBe(null);
```
This rule is enabled by default.
### Default configuration
The following patterns are considered warnings:
```js
expect(null).toBe(null);
expect(null).toEqual(null);
expect(null).toStrictEqual(null);
```
The following pattern is not warning:
```js
expect(null).toBeNull();
```
