十二. 其他协助类测试代码
这里就简单写一下对DependencyObjectTypeTest的测试代码:
1: using System;
2: using System.Windows;
3: using NUnit.Framework;
4:
5: namespace TDDDependencyTest.System.Windows
6: {
7: [TestFixture]
8: public class DependencyObjectTypeTest
9: {
10:
11: [Test]
12: void Accessors()
13: {
14: DependencyObjectType t = DependencyObjectType.FromSystemType(typeof(TestDepObj));
15: Assert.AreEqual("TestDepObj",t.Name);
16: Assert.AreEqual(typeof(TestDepObj),t.SystemType);
17: Assert.AreEqual(typeof(DependencyObject),t.BaseType.SystemType);
18: }
19:
20: [Test]
21: void IsInstanceOfType()
22: {
23: DependencyObjectType t = DependencyObjectType.FromSystemType(typeof(TestDepObj));
24: DependencyObjectType t2 = DependencyObjectType.FromSystemType(typeof(TestSubclass));
25: Assert.IsTrue(t.IsInstanceOfType(new TestSubclass()));
26: Assert.IsTrue(t2.IsSubclassOf(t));
27: Assert.IsFalse(t.IsSubclassOf(t2));
28: }
29:
30: [Test]
31: void TestCache()
32: {
33: DependencyObjectType t = DependencyObjectType.FromSystemType(typeof(TestDepObj));
34: DependencyObjectType t2 = DependencyObjectType.FromSystemType(typeof(TestDepObj));
35: Assert.AreSame(t,t2);
36: }
37: }
38: }
十三. 其他协助类的实现代码
