# Enforce valid `describe()` callback (`valid-describe`)
|
||
|
|
||
|
Using an improper `describe()` callback function can lead to unexpected test
|
||
|
errors.
|
||
|
|
||
|
## Rule Details
|
||
|
|
||
|
This rule validates that the second parameter of a `describe()` function is a
|
||
|
callback function. This callback function:
|
||
|
|
||
|
- should not be
|
||
|
[async](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function)
|
||
|
- should not contain any parameters
|
||
|
- should not contain any `return` statements
|
||
|
|
||
|
The following `describe` function aliases are also validated:
|
||
|
|
||
|
- `describe`
|
||
|
- `describe.only`
|
||
|
- `describe.skip`
|
||
|
- `fdescribe`
|
||
|
- `xdescribe`
|
||
|
|
||
|
The following patterns are considered warnings:
|
||
|
|
||
|
```js
|
||
|
// Async callback functions are not allowed
|
||
|
describe('myFunction()', async () => {
|
||
|
// ...
|
||
|
});
|
||
|
|
||
|
// Callback function parameters are not allowed
|
||
|
describe('myFunction()', done => {
|
||
|
// ...
|
||
|
});
|
||
|
|
||
|
//
|
||
|
describe('myFunction', () => {
|
||
|
// No return statements are allowed in block of a callback function
|
||
|
return Promise.resolve().then(() => {
|
||
|
it('breaks', () => {
|
||
|
throw new Error('Fail');
|
||
|
});
|
||
|
});
|
||
|
});
|
||
|
```
|
||
|
|
||
|
The following patterns are not considered warnings:
|
||
|
|
||
|
```js
|
||
|
describe('myFunction()', () => {
|
||
|
it('returns a truthy value', () => {
|
||
|
expect(myFunction()).toBeTruthy();
|
||
|
});
|
||
|
});
|
||
|
```
