How to validate dynamic UI with JQuery?

Home

Source: own resources, Authors: Agnieszka and Michał Komorowscy

One of the most interesting task I developed some time ago was a library responsible for the generation of dynamic UI based on XML description in ASP.NET MVC application. The task was not trivial. The UI had to change based on the selections made by a user. I had to support many different types of controls, relations between them e.g. if we select the checkbox A then the text box B should be disabled and of course validations. In order to perform the client side validations I used jQuery Unobtrusive Validation library. I thought that it'll work just like that but it turned out that a dynamic UI may cause problems. Here is what I did.

3 reasons why I don't use strict mocks

The majority, if not all, of mocking frameworks provides 2 types of mocks i.e. strict & loose.

I prefer to use loose mocks because with strict ones unit tests are fragile. Even the small change in the code can cause that unit tests will start failing. Secondly, if you need to set up many methods a test becomes less readable. Now, I can see one more reason.

Roslyn - How to create a custom debuggable scripting language?

Home

A screenshot comes from Visual Studio 2015

Sometime ago I decided to play a little bit with Cakebuild. It's a build automation tool/system that allows you to write build scripts using C# domain specific language. What's more it is possible to debug these scripts in Visual Studio. It is interesting because Cake scripts are neither "normal" C# files nor are added to projects (csproj). I was curious how it was achieved and it is result of my analysis. I'll tell you how to create a simple debuggable scripting language. By debuggable I mean that it'll be possible to debug scripts in our language in Visual Studio almost as any "normal" program in C#. Cakebuild uses Roslyn i.e. a compiler as a service from Microsft and we'll do the same.
