    Mocking Exceptions and Events with JustMock Free Edition

    [Cross Posted from http://www.skimedic.com/blog] Mocking Exceptions When writing unit tests, it is important to cover not only the successful execution path (commonly referred to as the “Happy” path), but also test the code that gets executed when things don’t go right (commonly referred to as the “Unhappy” path).  Testing for situations where services or databases are unavailable as well as erroneous user input are important aspects of ensuring quality in software.  Remember, if you don’t test it, your users will! We modify the LoginUser method to throw a custom exception when there is an exception is thrown from the LoginService.  To test this,...

    Sequential and Recursive Mocking with JustMock Free Edition

    [Cross Posted from http://www.skimedic.com/blog] Sequential Mocking One of the trickiest types of code to mock out for testing is recursive methods.  In a typical recursion, the same method is called multiple times, and each time there are typically different parameters passed in, and different return values.  To easily handle this, JustMock gives you two options: Adding InSequence() to each arrange Chaining Returns() calls together. To illustrate the first option, look at the following test: [Test] public void Show_Sequential_InSequence_Arrange_Option() { var service = Mock.Create<IService>(); Mock.Arrange(() => service.GetSum(Arg.AnyInt, Arg.AnyInt)) .Returns(4).InSequence(); Mock.Arrange(()...

    It’s Been A Long Run

    [Cross posted from .NET Musings]  I worked my first paying job involving computers in 1984.  After a degree in computer science from the school of engineering at Washington University in St. Louis, I started quite the run as a computer consultant.  My first jobs involved building custom computers and networks and programming the computers!  I’ve had a fabulous career as a consultant, and worked with a lot of fantastic people.  But I realized a while ago that I wanted to be something else when I grow up.  I just had no idea what that was.  In 1995, I started as a volunteer for...
