编辑:我刚刚尝试使用VS 2010,但问题没有发生。这个问题只发生在VS 2012上。这真的是一个错误吗?这也发生在我的两台独立笔记本电脑上,甚至在朋友的笔记本电脑上(刚刚获得最新代码)。
首先,问题的截图。这个方法都是 new 代码。
调试器正在从我最近的签入中跳过代码。下面的代码中的注释解释了我调试此方法时发生的情况。所以真的没有必要尝试理解代码;只是注意到正在跳过代码行。如果您认为代码与正在调试的程序集不匹配,请耐心等待。您将看到调试器识别新代码的位置,而不是现有代码。在删除磁盘上的代码并再次获取最新信息之后,这种行为发生在两台不同的笔记本电脑上。每个注释都会告诉您调试器是否命中一行。
[TestMethod()]
[DeploymentItem("PrestoCommon.dll")]
public void ApplicationShouldBeInstalledTest_UseCase9()
{
// Debugger hits this line
ApplicationServer appServerAccessor = new ApplicationServer();
// Debugger does not hit these next two lines
PrivateObject privateObject = new PrivateObject(appServerAccessor);
ApplicationServer appServer = ApplicationServerLogic.GetByName("server10");
// Debugger hits this line. Weirdness: both objects are null, and after this line runs,
// appServerAccessor is no longer null.
appServerAccessor.Id = appServer.Id;
// Skips this line
ApplicationWithOverrideVariableGroup appWithValidGroup = appServer.ApplicationsWithOverrideGroup[0];
// Debugger hits this line, but F11 doesn't take me into the method.
appWithValidGroup.CustomVariableGroup = CustomVariableGroupLogic.GetById("CustomVariableGroups/4");
// Skips this line
Assert.AreEqual(true, true);
}
反汇编只显示实际被击中的代码行。
现在,看看这个。如果我添加一行新代码,调试器会识别它,并且其他代码行会发生变化,只要调试器能够识别。在方法中,第二行代码是新的。
[TestMethod()]
[DeploymentItem("PrestoCommon.dll")]
public void ApplicationShouldBeInstalledTest_UseCase9()
{
// Debugger hits this line
ApplicationServer appServerAccessor = new ApplicationServer();
// New line. It's recognized by the debugger, and it shows up in the disassembly.
if (DateTime.Now > DateTime.Now.AddHours(1)) { return; }
// Debugger does not hit these next two lines
PrivateObject privateObject = new PrivateObject(appServerAccessor);
ApplicationServer appServer = ApplicationServerLogic.GetByName("server10"); // Gets hit now.
// Debugger hits this line. Weirdness: both objects are null, and after this line runs,
// appServerAccessor is no longer null.
appServerAccessor.Id = appServer.Id; // No longer gets hit.
// Skips this line (now it's getting hit)
ApplicationWithOverrideVariableGroup appWithValidGroup = appServer.ApplicationsWithOverrideGroup[0];
// Debugger hits this line, but F11 doesn't take me into the method. Now this gets skipped.
appWithValidGroup.CustomVariableGroup = CustomVariableGroupLogic.GetById("CustomVariableGroups/4");
// Skips this line. Still skipped.
Assert.AreEqual(true, true);
}
这是反汇编的部分快照,显示了新的代码行:
这怎么可能发生?
增加了奇怪性,有一点甚至还没有回复:
if (DateTime.Now > DateTime.Now.AddDays(1)) { return; }
我尝试过的事情:
- 从硬盘驱动器中删除源代码并强制获取最新信息
- 修复VS 2012
- 做一些VS clean-up
- 使用VS 2010,更改密码,办理登机手续,获取VS 2012的最新信息
- 重新启动
- 其他(不记得所有)
答案 0 :(得分:4)
这似乎是针对单元测试的。在VS 2012中:
注意,我有访问源代码的优势,我下载了Presto(http://presto.codeplex.com/)。
