+# Suggest using `expect.assertions()` OR `expect.hasAssertions()` (prefer-expect-assertions)
+
+Ensure every test to have either `expect.assertions(<number of assertions>)` OR
+`expect.hasAssertions()` as its first expression.
+
+## Rule details
+
+This rule triggers a warning if,
+
+* `expect.assertions(<number of assertions>)` OR `expect.hasAssertions()` is not
+  present as first statement in a test, e.g.:
+
+```js
+test('my test', () => {
+  expect(someThing()).toEqual('foo');
+});
+```
+
+* `expect.assertions(<number of assertions>)` is the first statement in a test
+  where argument passed to `expect.assertions(<number of assertions>)` is not a
+  valid number, e.g.:
+
+```js
+test('my test', () => {
+  expect.assertions('1');
+  expect(someThing()).toEqual('foo');
+});
+```
+
+### Default configuration
+
+The following patterns are considered warnings:
+
+```js
+test("my test", () => {
+  expect.assertions("1");
+  expect(someThing()).toEqual("foo");
+});
+
+test("my test", () => {
+  expect.(someThing()).toEqual("foo");
+});
+```
+
+The following patterns would not be considered warnings:
+
+```js
+test('my test', () => {
+  expect.assertions(1);
+  expect(someThing()).toEqual('foo');
+});
+
+test('my test', () => {
+  expect.hasAssertions();
+  expect(someThing()).toEqual('foo');
+});
+```
