Mocks a dart byte stream. Useful for simulating a network connection in unit tests.

Features

• Mocks a standard dart byte stream Stream<List<int>>.
• Random byte length for each response.
• Random delays between responses.
• Can throw an exception at a random moment if configured.

Usage

Install and import this package:

import 'package:mock_byte_stream/mock_byte_stream.dart';

Example:

import 'dart:convert';

import 'package:mock_byte_stream/mock_byte_stream.dart';

var bytes = ascii.encode('<DATA...>');

void main() async {
  var mbs = MockByteStream(bytes, 50,         // Each response has a size of 1-50 bytes.
      minDelay: Duration(milliseconds: 10),   // Random delays.
      maxDelay: Duration(milliseconds: 1000));

  // Use the mocked stream.
  await for (var data in mbs.stream()) {
    print(ascii.decode(data));
  }
}
