Function expectedToFail

expectedToFail(
    config: any,
    message: string,
    asyncFunc: () => any,
    expectNothing?: { expectNothing?: boolean },
): Promise<void>
Mark a code section as expected to fail. If the async function throws an error, the error will be included in reports, but not counted as a test failure. If the async function succeeds, a warning will be printed.
Parameters
- config: any
  The pentf configuration.
- message: string
  Error message to show when the section fails (recommended: ticket URL)
- asyncFunc: () => any
  The asynchronous section which is part of the test.
- expectNothing: { expectNothing?: boolean } = {}
  Do nothing – this is convenient if the code is expected to work on some environments. (default: false)
Returns Promise<void>
Example
```
await expectedToFail(config, 'BUG-1234', async() => {
    ...
}, {
    expectNothing: config.env === 'very-good-environment',
});
```
