+# Disallow specific `jest.` methods (`no-restricted-jest-methods`)
+
+💼 This rule is enabled in the following
+[configs](https://github.com/jest-community/eslint-plugin-jest/blob/main/README.md#shareable-configurations):
+`all`.
+
+<!-- end rule header -->
+
+You may wish to restrict the use of specific `jest` methods.
+
+## Rule details
+
+This rule checks for the usage of specific methods on the `jest` object, which
+can be used to disallow curtain patterns such as spies and mocks.
+
+## Options
+
+Restrictions are expressed in the form of a map, with the value being either a
+string message to be shown, or `null` if a generic default message should be
+used.
+
+By default, this map is empty, meaning no `jest` methods are banned.
+
+For example:
+
+```json
+{
+  "jest/no-restricted-jest-methods": [
+    "error",
+    {
+      "advanceTimersByTime": null,
+      "spyOn": "Don't use spies"
+    }
+  ]
+}
+```
+
+Examples of **incorrect** code for this rule with the above configuration
+
+```js
+jest.useFakeTimers();
+it('calls the callback after 1 second via advanceTimersByTime', () => {
+  // ...
+
+  jest.advanceTimersByTime(1000);
+
+  // ...
+});
+
+test('plays video', () => {
+  const spy = jest.spyOn(video, 'play');
+
+  // ...
+});
+```
