TDD Example for Business Apps

I understand the general idea about unit testing and have used it in scenarios where complex interactions were happening in a system, but I still have a question about all of those principles coming together. We are cautioned about not testing the framework, or the database. Good UI design does not lend itself to non-human testing. UI...

asp.net mvc controller actions testing

I was just wondering how others are going about testing controller actions in asp.net mvc? Most of my dependencies are injected in to my controllers so there is a not a huge amount of logic in the action methods but there may be some conditional logic for example which I think is unavoidable. In the past I have written tests for these a...

Visual Studio 2010 and Test Driven Development

I'm making my first steps in Test Driven Development with Visual Studio. I have some questions regarding how to implement generic classes with VS 2010. First, let's say I want to implement my own version of an ArrayList. I start by creating the following test (I'm using in this case MSTest): [TestMethod] public void Add_10_Items_Remove...

Using Robot Framework for ATDD

I would like to hear other people's experience with using Robot Framework for automated acceptance testing. What are its major strengths and weaknesses as well as any comparison with other frameworks (mainly Fitness and Selenium)? The code that will be tested is real-time, legacy code, mainly in C++. ...

How can i mock or test my deferred evaluation/execution functionality?

I have what could be seen as a bizarre hybrid of IQueryable<T> and IList<T> collections of domain objects passed up my application stack. I'm trying to maintain as much of the 'late querying' or 'lazy loading' as possible. I do this in two ways: By using a LinqToSql data layer and passing IQueryable<T>s through by repositories and to m...

Unit testing a SQL code generator

The team I'm on is currently writing code in TSQL to generate TSQL code that will be saved as scripts and later run. We're having a little difficulty in separating our unit tests between testing the code generator parts and testing the actual code that they generate. I've read through another similar question, but I was hoping to get so...

How do I test a ruby Mixin Module?

I'd like to know the best way to approach testing ruby mixin modules, in this case for use with ActiveRecord models, but really this is a general quesiton that applies to any class that you are extending with a mixin. Is it better to attempt to stub all of the necessary functionality of the Class that your mixin is extending, or just te...

Entity Framework with RIA services, Silverlight - tradeoff of decoupling versus rapid development

I've been playing around lately with Entity Framework, WCF RIA Services, and Silverlight 4. I'm impressed by how rapidly you can develop an application with these tools, and you get a lot "for free", such as the Silverlight UI automatically knowing about certain validations that are included as DataAnnotations on the EF model. However,...

Am I just not understanding TDD unit testing (Asp.Net MVC project)?

I am trying to figure out how to correctly and efficiently unit test my Asp.net MVC project. When I started on this project I bought the Pro ASP.Net MVC, and with that book I learned about TDD and unit testing. After seeing the examples, and the fact that I work as a software engineer in QA in my current company, I was amazed at how aw...

Reflection in unit tests for checking code coverage

Here's the scenario. I have VO (Value Objects) or DTO objects that are just containers for data. When I take those and split them apart for saving into a DB that (for lots of reasons) doesn't map to the VO's elegantly, I want to test to see if each field is successfully being created in the database and successfully read back in to reb...

Unit Testing: hard dependency MessageBox.Show()

What ways can the SampleConfirmationDialog be unit tested? The SampleConfirmationDialog would be exercised via acceptance tests, however how could we unit test it, seeing as MessageBox is not abstract and no matching interface? public interface IConfirmationDialog { /// <summary> /// Confirms the dialog with the user /// </s...

how often should the entire suite of a system's unit tests be run?

Generally, I'm still very much a unit testing neophyte. BTW, you may also see this question on other forums like xUnit.net, et cetera, because it's an important question to me. I apoligize in advance for my cross posting; your opinions are very important to me and not everyone in this forum belongs to the other forums too. I was ...

Any suggestions for improvement on this style for BDD/TDD?

I was tinkering with doing the setups with our unit test specifciations which go like Specification for SUT when behaviour X happens in scenario Y Given that this thing And also this other thing When I do X... Then It should do ... And It should also do ... I wrapped each of the steps of the GivenThat in Actions... any f...

First TDD, Simple 2-tier C# Project - what do I unit test?

This is probably a stupid question but my googling isn't finding a satisfactory answer. I'm starting a small project in C#, with just a business layer and a data access layer - strangely, the UI will come later, and I have very little (read:no) concept / control over what it will look like. I would like to try TDD for this project. I'...

Implementing a Stack using Test-Driven Development

I am doing my first steps with TDD. The problem is (as probably with everyone starting with TDD), I never know very well what kind of unit tests to do when I start working in my projects. Let's assume I want to write a Stack class with the following methods(I choose it as it's an easy example): Stack<T> - Push(element : T) - Pop() : ...

TDD, Unit Test and architectural changes

I'm writing an RPC middleware in C++. I have a class named RPCClientProxy that contains a socket client inside: class RPCClientProxy { ... private: Socket* pSocket; ... } The constructor: RPCClientProxy::RPCClientProxy(host, port) { pSocket = new Socket(host, port); } As you can see, I don't need to tell the user that I...

C++ & proper TDD

Hi! I recently tried developing a small-sized project in C# and during the whole project our team used the Test-Driven-Development (TDD) technique (xunit, moq). I really think this was awesome, because (when paired with C#) this approach allowed to relax when coding, relax when projecting and relax when refactoring. I suspect that all ...

Unit testing ASP.NET Code behind.

I've been reading about MVC in which the authors suggest that testability is one of the major strengths of MVC. They go to compare it with ASP.NET WebForms and how difficult it is to test the code behind in WebForms. I do understand it's difficult but can someone explain how unit tests were written to test code behind logic in the old ...

A standard event messaging system with AJAX?

Is there any standards or messaging framework for AJAX? Right now I have a single page that loads content using Ajax. Because I had a complex form for data entry as part of my content, I need to validate certain events that can occur in my form. So after some adjustments driven by my tests: asyncShould("search customer list click", 3, ...

Changing User in MVC 2 MockHttpContext breaks Test?

I changed the following line: private readonly IPrincipal _user = new GenericPrincipal(new GenericIdentity("someUser"), null /* roles */); to private readonly IPrincipal _user = new GenericPrincipal(new GenericIdentity("realUser"), null /* roles */); and the following test broke, but I am not sure why and I am not ...
