Cannot find Assert.Fail and Assert.Pass or equivalent
提问by naeron84
I used to use these in NUnit and they are really useful. Any idea how to do something like that?
我曾经在 NUnit 中使用过这些，它们非常有用。知道如何做这样的事情吗？
EDIT, CODE SAMPLE:
编辑，代码示例：
bool condition = false;//would be nice not to have this
observable.Subscribe(_ =>
{
if (real test)
condition= true;//Assert.Pass()
});
StartObservable();
Assert.True(condition);//Assert.Fail()

The documentation includes a comparison chartincluding this:
该文档包括一个比较图表，其中包括：
Fail- xUnit.net alternative:Assert.True(false, "message")
Fail- xUnit.net 替代方案：Assert.True(false, "message")
(It doesn't show Assert.Pass, and I've never used that myself, but I suspect the alternative is just to return from the test. Of course that doesn't help if you want to throw it in a nested method call. My suspicionis that it's not very frequently used in NUnit, hence its absence in the comparison chart.)
（它没有显示Assert.Pass，而且我自己从未使用过，但我怀疑另一种选择只是从测试中返回。当然，如果您想将其放入嵌套方法调用中，那将无济于事。我的怀疑是因为它在 NUnit 中不是很常用，因此它在比较图中没有出现。）

An alternative to Assert.Fail("messsage")suggested by xUnit docs
xUnit 文档Assert.Fail("messsage")建议的替代方案
xUnit.net alternative: Assert.True(false, "message")
xUnit.net 替代方案：Assert.True(false, "message")
has a downside – its output is
有一个缺点——它的输出是
message
Expected: True
Actual: False
To get rid of
摆脱
Expected: True Actual: False
Expected: True Actual: False
don't call Assert.True(false, "message")throw Xunit.Sdk.XunitExceptioninstead.
For example, create a helper method similar to this:
不要调用Assert.True(false, "message")throw Xunit.Sdk.XunitException。
例如，创建一个类似于此的辅助方法：
public static class MyAssert
{
public static void Fail(string message)
=> throw new Xunit.Sdk.XunitException(message);
}

Just throw an exception to satisfy both requirements (exiting a nested loop and an alternative to the missing Assert.Fail method). Only issue is there is no decent base exception (e.g. TestException) to use in order to avoid getting warnings about using the base Exception class, so something more directed like an InvalidOperationException is probably a good choice.
只需抛出一个异常即可满足这两个要求（退出嵌套循环和缺少 Assert.Fail 方法的替代方法）。唯一的问题是没有合适的基本异常（例如 TestException）来避免使用基本异常类的警告，所以像 InvalidOperationException 这样更直接的东西可能是一个不错的选择。
