Calls `assert.deepStrictEqual` and then creates a visual representation of the difference between objects if it throws.
- actual* ?undefined: The actual value.
- expected* ?undefined: The expected value.
- message `string` (optional): The message with which to fail if the assertion didn't succeed.
async assertThrows(): void
Assert that a function throws and check the thrown error properties.
```js
await throws({
fn: method,
args: ['test', true],
message: /An error occurred:/, // regex
code: 'ENOTEST', // string
stack(stack) { // function
equal(stack.length, 2)
}
})
```
- config* _assertThrows.Config: Parameters to the `assert-throws` method.
!(string \| RegExp \| !Function) `_assertThrows.Assertion`: An assertion to perform.
