JustMock 和大型测试运行的问题

Question

好的，我对 JustMock 有一个问题，希望有人能帮助我解决。 我有一堂课有几种测试方法（大约 80 个）。当独立运行时，这些方法中的每一个都会出色地通过。然而，我有一些方法，当作为更大的测试运行（比如整个类）的一部分运行时将会失败。

这些测试方法使用 JustMock 模拟框架模拟非公共方法，然后调用调用每个私有方法的公共接口方法。 下面是一个示例，

 ///<summary>
///  A test for CheckCommError
///</summary>
[TestMethod]
public void CheckCommErrorWithErrorTest()
{
    var message = new byte[] { (byte)EagleMessageTypes.SendCommError,BitConverter.GetBytes((ushort)10)[0], BitConverter.GetBytes((ushort)10)[1] };

    bool expected = false; // TODO: Initialize to an appropriate value
    bool actual;
    //mock the other members in EagleUtility that are being used...
    var target = new EagleUtility();
    bool called = true;
    Mock.NonPublic.Arrange<bool>(target, "CheckMinimumSize", ArgExpr.IsAny<BasicEagleMessage>(), Arg.AnyInt).IgnoreArguments().DoInstead(
        (BasicEagleMessage arg1, int arg2) => called = true).Returns(true).MustBeCalled();
    Mock.NonPublic.Arrange<bool>(target, "CheckMessageLength", Arg.AnyInt, ArgExpr.IsAny<BasicEagleMessage>()).IgnoreArguments().DoInstead(
        (int arg1, BasicEagleMessage arg2) => called = true).Returns(true).MustBeCalled();
    Mock.NonPublic.Arrange<bool>(target, "VerifyCheckSum", ArgExpr.IsAny<byte[]>()).IgnoreArguments().DoInstead(
        (byte[] arg1) => called = true).Returns(true).MustBeCalled();
    Mock.NonPublic.Arrange<bool>(target, "ValidateLegacyMessageType", ArgExpr.IsAny<BasicEagleMessage>()).IgnoreArguments().DoInstead(
        (BasicEagleMessage arg1) => called = true).Returns(true).MustBeCalled();
    actual = target.ValidateMessage(message, 3, TowerTypes.Tower4800);
    Assert.AreEqual(expected, actual);
    Mock.Assert(target);
}

///<summary>
///  A test for CheckMessageLength
///</summary>
[TestMethod]
public void CheckMessageLengthTest()
{
    var message = new byte[] { (byte)3, BitConverter.GetBytes((ushort)59006)[0], BitConverter.GetBytes((ushort)59006)[1], 0 };
    var byteCount = 32486;
    bool expected = true;
    bool actual;
    //mock the other members in EagleUtility that are being used...
    var target = new EagleUtility();
    bool called = true;
    Mock.NonPublic.Arrange<bool>(target, "CheckMinimumSize", ArgExpr.IsAny<BasicEagleMessage>(), Arg.AnyInt).IgnoreArguments().DoInstead(
        (BasicEagleMessage arg1, int arg2) => called = true).Returns(true).MustBeCalled();
    Mock.NonPublic.Arrange<bool>(target, "CheckCommError", ArgExpr.IsAny<BasicEagleMessage>()).IgnoreArguments().DoInstead(
        (BasicEagleMessage arg2) => called = true).Returns(true).MustBeCalled();
    Mock.NonPublic.Arrange<bool>(target, "VerifyCheckSum", ArgExpr.IsAny<byte[]>()).IgnoreArguments().DoInstead(
        (byte[] arg1) => called = true).Returns(true).MustBeCalled();
    Mock.NonPublic.Arrange<bool>(target, "ValidateLegacyMessageType", ArgExpr.IsAny<BasicEagleMessage>()).IgnoreArguments().DoInstead(
        (BasicEagleMessage arg1) => called = true).Returns(true).MustBeCalled();
    actual = target.ValidateMessage(message, byteCount, TowerTypes.Tower4800);
    Assert.AreEqual(expected, actual);
    Mock.Assert(target);
}

当我单独运行每个方法时，它们会通过，但是当作为一组运行时，第一个方法会通过，而第二个方法会失败。根据我运行测试的方式（哪个测试运行程序），测试方法在不同的断言上失败，使用 mstest 它在 Asser.AreEqual 上失败，而使用 JustCode testrunner 它在 Mock.Assert 上失败（说明标记为 MustBeCalled 的方法未被调用） ）。

我有 Mock.Initialize();在我的测试类的类初始化函数中。

我感谢任何帮助，并提前感谢大家。
