Publicメソッド
通常ケース
[TestMethod()]publicvoidPublicMethodTest(){varinstance=newTestTargetClass();varret=instance.PublicMethod(1);Assert.AreEqual(ret,2);}Privateメソッド+Privateメンバ変数
PrivateObjectのSetFieldOrProperty()でメンバ変数を変更．
またはSetField()，SetProperty()．
privateObject.Invoke()でメソッド呼び出し．第2引数以降で呼び出したいメソッドの引数を設定．
[TestMethod()]publicvoidPrivateMethodTest(){varinstance=newTestTargetClass();varprivateObject=newPrivateObject(instance);// メンバ変数値変更privateObject.SetFieldOrProperty("_privateMember",100);// Privateメソッド呼び出しvarret=privateObject.Invoke("PrivateMethod",100,200);Assert.AreEqual(ret,300);}Privateメソッド(非同期)
呼び出しを戻り値の型でくるんでawait．
[TestMethod()]publicasyncTaskPrivateMethodAsyncTest(){varinstance=newTestTargetClass();varprivateObject=newPrivateObject(instance);// 戻り値の型でくるんでawaitvarret=await(privateObject.Invoke("PrivateMethodAsync",100,200)asTask<int>);Assert.AreEqual(ret,300);}PrivateStaticメソッド+PrivateStaticメンバ変数
PrivateTypeのSetStaticFieldOrProperty()とInvokeStatic()を使用．
基本は通常のPrivateのときと同じ．
[TestMethod()]publicvoidGetPrivateStaticMemberTest(){varprivateType=newPrivateType(typeof(TestTargetClass));// static変数値変更privateType.SetStaticFieldOrProperty("_privateStaticMember","ヨシッ！");// staticメソッド呼び出しvarret=privateType.InvokeStatic("GetPrivateStaticMember");Assert.AreEqual(ret,"ヨシッ！");}
