What will we cover?

Client testsServer tests

Why test?

I always mess up some mundane detail!

I must have put a decimal point in the wrong place.

Client tests

test_index.dart import 'package:unittest/unittest.dart';import 'package:unittest/html_enhanced_config.dart';...main() { useHtmlEnhancedConfiguration();

test("url includes scheme", () { expect(isValidUrl(“www.dartlang.org”), false); expect(isValidUrl(“http://www.dartlang.org”), true); });

HTML unit test

test_index.dart import 'package:unittest/unittest.dart';import 'package:unittest/html_enhanced_config.dart';...main() { useHtmlEnhancedConfiguration();

test("url includes scheme", () { expect(isValidUrl(“www.dartlang.org”), false); expect(isValidUrl(“http://www.dartlang.org”), true); });

HTML unit test

test_index.dart import 'package:unittest/unittest.dart';import 'package:unittest/html_enhanced_config.dart';...main() { useHtmlEnhancedConfiguration();

test("url includes scheme", () { expect(isValidUrl(“www.dartlang.org”), false); expect(isValidUrl(“http://www.dartlang.org”), true); });

Server

server.dart void main() { ... app.post("/").listen((request) { String url = request.param('url'); String hash = toHash(url); client.set(hash, url).then((_)=>request.response.json(hash);); }); ...

Server tests

server_tests.dartimport 'package:unittest/unittest.dart';import 'package:unittest/vm_config.dart';import 'server.dart' as server;

void main() { useVMConfiguration();

String URL = 'http://www.meetup.com/gdg-silicon-valley’;

test('HashURL', () { expect(server.toHash(URL), isNotNull); expect(server.toHash(URL), '287b6d95'); ...

server_tests.dartimport 'package:unittest/unittest.dart';import 'package:unittest/vm_config.dart';import 'server.dart' as server;

void main() { useVMConfiguration();

String URL = 'http://www.meetup.com/gdg-silicon-valley’;

test('HashURL', () { expect(server.toHash(URL), isNotNull); expect(server.toHash(URL), '287b6d95'); ...

server_tests.dartimport 'package:unittest/unittest.dart';import 'package:unittest/vm_config.dart';import 'server.dart' as server;

void main() { useVMConfiguration();

String URL = 'http://www.meetup.com/gdg-silicon-valley’;

test('HashURL', () { expect(server.toHash(URL), isNotNull); expect(server.toHash(URL), '287b6d95'); ...
