    Rule Details

    Disallow string interpolation inside inline snapshots. Interpolation prevents Jest from updating snapshots; instead, overload dynamic properties with a matcher via property matchers.

    Examples of incorrect code for this rule:

    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:

    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`,
);
