# Suggest using `expect.assertions()` OR `expect.hasAssertions()` (`prefer-expect-assertions`)
2020-03-07 11:45:40 +08:00
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
2020-09-13 06:19:45 +08:00
test('my test', () => {
expect.assertions('1');
expect(someThing()).toEqual('foo');
2020-03-07 11:45:40 +08:00
});
2020-09-13 06:19:45 +08:00
test('my test', () => {
expect(someThing()).toEqual('foo');
2020-03-07 11:45:40 +08:00
});
```
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');
});
```

## Options
#### `onlyFunctionsWithAsyncKeyword`
When `true`, this rule will only warn for tests that use the `async` keyword.
```json
{
"rules": {
"jest/prefer-expect-assertions": [
"warn",
{ "onlyFunctionsWithAsyncKeyword": true }
]
}
}
```
When `onlyFunctionsWithAsyncKeyword` option is set to `true`, the following
pattern would be a warning:
```js
test('my test', async () => {
const result = await someAsyncFunc();
expect(result).toBe('foo');
});
```
While the following patterns would not be considered warnings:
```js
test('my test', () => {
const result = someFunction();
expect(result).toBe('foo');
});
test('my test', async () => {
expect.assertions(1);
const result = await someAsyncFunc();
expect(result).toBe('foo');
});
```
