throwError(errorType:closure:)

A Nimble matcher that succeeds when the actual expression throws an error of the specified type or from the specified case.

public func throwError<T: Error>(errorType: T.Type, closure: ((T) -> Void)? = nil) -> Predicate<Any>

Errors are tried to be compared by their implementation of Equatable, otherwise they fallback to comparision by _domain and _code.

Alternatively, you can pass a closure to do any arbitrary custom matching to the thrown error. The closure only gets called when an error was thrown.

nil arguments indicates that the matcher should not attempt to match against that parameter.
