2009年3月16日 · Unit testing is a massive topic and to fully get an understanding of how it can best benefit you I'd recommend getting hold of a book on unit testing such as "Test Driven Development by Example" which will give you a good grasp on the concepts and how you can apply them to your code.

The unit test then becomes [TestMethod] public void TestValuesController() { ValuesController controller = new ValuesController(); var result = controller.GetHeaderValue("27"); Assert.AreEqual(result, "27"); } While you can mock the HttpContext, in my opinion it is something that should be avoided unless you have no choice.

2017年7月15日 · The test always passes event if I change the argument of subjectService.callNextOnSubject from 'test' to anything else. I have also tried wrapping everything with async and fakeAsync, but the result is the same. What would be the correct way to test if callNextOnSubject is emitting data to the serviceSubjectProperty$ Subject?

2010年9月23日 · The first and likely most prevalent class of database unit test is a feature test. In my mind, feature tests test the core features—or APIs, if you will—of your database from the database consumer's perspective. Testing a database's programmability objects …

2011年11月21日 · Now to unit test this, you create a "mock" implementation of the ILocalDetails interface whose getLocalHost() method throws the exception you want under the appropriate conditions. Then you create a unit text for SomeClass.getServerName() , arranging that the instance of SomeClass uses an instance of your "mock" class instead of the normal one.

Worth mentioning - you can often avoid the need for unit testing your internal methods by using System.Diagnostics.Debug.Assert() within the methods themselves. – Mike Marynowski Commented Mar 30, 2017 at 2:32

I know there are already a few questions regarding recommendations for C++ unit test frameworks, but all the answers did not help as they just recommend one of the frameworks but do not provide any information about a (feature) comparison. I think the most interesting frameworks are CppUnit, Boost and the new Google testing framework.

2009年4月12日 · In all unit testing frameworks I am familiar with, Assert.Fail works by throwing an exception, so the generic catch will actually mask the failure of the test. If SomethingThatCausesAnException() does not throw, the Assert.Fail will, but that will never bubble out to the test runner to indicate failure.

From outside the black box, the response stream is essentially the same. The test must know how the controller implemented the return call to test it in this way. Instead, use the HttpResponseMessage object from the IHttpActionResult returned. This ensures the test can be consistent, even when the controller code may not be:

2016年1月15日 · Just to clarify, the System.loadlibrary() call was failing because the junit unit test uses host/system environment which was windows in my case. Hence the loadlibrary() call was trying to search for the .so files in standard shared libary folders. But this isn't what I was expecting to happen.
