expectOneWhere method

PendingRequest expectOneWhere(bool predicate(HttpRequest), { String description = 'matching request', })

Matches exactly one request without consuming candidates on failure.

Implementation

PendingRequest expectOneWhere(bool Function(HttpRequest) predicate,
    {String description = 'matching request'}) {
  final candidates = _pending
      .where((item) => !item.matched && predicate(item.request))
      .toList();
  if (candidates.length != 1) {
    throw StateError('Expected one $description, found ${candidates.length}. '
        'Outstanding: $_outstanding');
  }
  candidates.single.matched = true;
  return candidates.single;
}
