## Rule Details

This rule aims to enforce passing a named function to `describe()` instead of an equivalent hardcoded string.

Passing named functions means the correct title will be used even if the function is renamed.
This rule will report if a string is passed to a `describe()` block if:

- The string matches a function imported into the file
- That function's name also matches the test file's name

Examples of **incorrect** code for this rule:

```ts
// myFunction.test.js
import { myFunction } from './myFunction'

describe('myFunction', () => {
  // ...
})
```

Examples of **correct** code for this rule:

```ts
// myFunction.test.js
import { myFunction } from './myFunction'

describe(myFunction, () => {
  // ...
})
```
