# Suggest using inline snapshots (`prefer-inline-snapshots`)
## Deprecated
This rule has been deprecated in favor of
[`no-restricted-matchers`](no-restricted-matchers.md) with the following config:
```json
{
"rules": {
"jest/no-restricted-matchers": [
"error",
{
"toThrowErrorMatchingSnapshot": "Use `toThrowErrorMatchingInlineSnapshot()` instead",
"toMatchSnapshot": "Use `toMatchInlineSnapshot()` instead"
}
]
}
}
```
---
In order to make snapshot tests more manageable and reviewable
`toMatchInlineSnapshot()` and `toThrowErrorMatchingInlineSnapshot` should be
used to write the snapshots' inline in the test file.
## Rule details
This rule triggers a warning if `toMatchSnapshot()` or
`toThrowErrorMatchingSnapshot` is used to capture a snapshot.
The following pattern is considered warning:
```js
expect(obj).toMatchSnapshot();
```
```js
expect(error).toThrowErrorMatchingSnapshot();
```
The following pattern is not warning:
```js
expect(obj).toMatchInlineSnapshot();
```
```js
expect(error).toThrowErrorMatchingInlineSnapshot();
```
