# Disallow use of deprecated functions (`no-deprecated-functions`)
|
|
|
|
Over the years Jest has accrued some debt in the form of functions that have
|
|
either been renamed for clarity, or replaced with more powerful APIs.
|
|
|
|
While typically these deprecated functions are kept in the codebase for a number
|
|
of majors, eventually they are removed completely.
|
|
|
|
This rule requires knowing which version of Jest you're using - see
|
|
[this section of the readme](../../README.md#jest-version-setting) for details
|
|
on how that is obtained automatically and how you can explicitly provide a
|
|
version if needed.
|
|
|
|
## Rule details
|
|
|
|
This rule warns about calls to deprecated functions, and provides details on
|
|
what to replace them with, based on the version of Jest that is installed.
|
|
|
|
This rule can also autofix a number of these deprecations for you.
|
|
|
|
### `jest.resetModuleRegistry`
|
|
|
|
This function was renamed to `resetModules` in Jest 15, and is scheduled for
|
|
removal in Jest 27.
|
|
|
|
### `jest.addMatchers`
|
|
|
|
This function was replaced with `expect.extend` in Jest 17, and is scheduled for
|
|
removal in Jest 27.
|
|
|
|
### `require.requireActual` & `require.requireMock`
|
|
|
|
These functions were replaced in Jest 21 and removed in Jest 26.
|
|
|
|
Originally, the `requireActual` & `requireMock` the `requireActual`&
|
|
`requireMock` functions were placed onto the `require` function.
|
|
|
|
These functions were later moved onto the `jest` object in order to be easier
|
|
for type checkers to handle, and their use via `require` deprecated. Finally,
|
|
the release of Jest 26 saw them removed from the `require` function all
|
|
together.
|
|
|
|
### `jest.runTimersToTime`
|
|
|
|
This function was renamed to `advanceTimersByTime` in Jest 22, and is scheduled
|
|
for removal in Jest 27.
|
|
|
|
### `jest.genMockFromModule`
|
|
|
|
This function was renamed to `createMockFromModule` in Jest 26, and is scheduled
|
|
for removal in a future version of Jest.
