Exception handling and testing with pytest and hypothesis

阅读更多关于 Exception handling and testing with pytest and hypothesis

问题 I'm writing tests for a statistical analysis with hypothesis. Hypothesis led me to a ZeroDivisionError in my code when it is passed very sparse data. So I adapted my code to handle the exception; in my case, that means log the reason and reraise the exception. try: val = calc(data) except ZeroDivisionError: logger.error(f"check data: {data}, too sparse") raise I need to pass the exception up through the call stack because the top-level caller needs to know there was an exception so that it

Well now that we're adding

问题 This is weird, but all of a sudden the ExpectedExceptionAttribute quit working for me the other day. Not sure what's gone wrong. I'm running VS 2010 and VS 2005 side-by-side.

问题 I'm trying to refactor this old code that does not use ExpectedException so that it does use it: try { //... fail(); } catch (UniformInterfaceException e) { assertEquals(404, e.getResponse().getStatus()); assertEquals("Could not find facility for aliasScope = DOESNTEXIST", e.getResponse().getEntity(String.class)); } And I can't figure out how to do this because I don't know how to check the value of e.getResponse().getStatus() or e.getResponse().getEntity(String.class) in an ExpectedException

问题 How do you do the equivalent of: [Test, ExpectedException( typeof(ArgumentOutOfRangeException) )] void Test_Something_That_Throws_Exception() { throw gcnew ArgumentOutOfRangeException("Some more detail"); } ...in C++ (the example there is C#)? As far as I can see, there's no typeof() function for the C++ implementation of NUnit. 回答1: To avoid anyone else hunting around for ages trying to find it, here's the solution: [Test, ExpectedException( ArgumentOutOfRangeException::typeid )] void Test
