+# Prefer having hooks in a consistent order (`prefer-hooks-in-order`)
+
+While hooks can be setup in any order, they're always called by `jest` in this
+specific order:
+
+1. `beforeAll`
+1. `beforeEach`
+1. `afterEach`
+1. `afterAll`
+
+This rule aims to make that more obvious by enforcing grouped hooks be setup in
+that order within tests.
+
+## Rule Details
+
+Examples of **incorrect** code for this rule
+
+```js
+/* eslint jest/prefer-hooks-in-order: "error" */
+
+describe('foo', () => {
+  beforeEach(() => {
+    seedMyDatabase();
+  });
+
+  beforeAll(() => {
+    createMyDatabase();
+  });
+
+  it('accepts this input', () => {
+    // ...
+  });
+
+  it('returns that value', () => {
+    // ...
+  });
+
+  describe('when the database has specific values', () => {
+    const specificValue = '...';
+
+    beforeEach(() => {
+      seedMyDatabase(specificValue);
+    });
+
+    it('accepts that input', () => {
+      // ...
+    });
+
+    it('throws an error', () => {
+      // ...
+    });
+
+    afterEach(() => {
+      clearLogger();
+    });
+    beforeEach(() => {
+      mockLogger();
+    });
+

+    });
+  });
