Disallow string interpolation inside snapshots (no-interpolation-in-snapshots)

Prevents the use of string interpolations in snapshots.

Rule Details

Interpolation prevents snapshots from being updated. Instead, properties should be overloaded with a matcher by using property matchers.

Examples of incorrect code for this rule:

``js expect(something).toMatchInlineSnapshot(Object { property: ${interpolated} }`, );

expect(something).toMatchInlineSnapshot( { other: expect.any(Number) }, Object { other: Any<Number>, property: ${interpolated} }, );

expect(errorThrowingFunction).toThrowErrorMatchingInlineSnapshot( ${interpolated}, ); ```

Examples of correct code for this rule:

```js expect(something).toMatchInlineSnapshot();

expect(something).toMatchInlineSnapshot( Object { property: 1 }, );

expect(something).toMatchInlineSnapshot( { property: expect.any(Date) }, Object { property: Any<Date> }, );

expect(errorThrowingFunction).toThrowErrorMatchingInlineSnapshot();

expect(errorThrowingFunction).toThrowErrorMatchingInlineSnapshot( Error Message, ); ```

When Not To Use It

Don't use this rule on non-jest test files.
