In this blog post, Rui Sun and Andre Hamilton explore some Visual Studio 2012 capabilities that will make it easier to test and verify Windows 8 applications. Visual Studio 2012 has a simulator that reduces your need to have physical devices of every form factor at your disposal for testing. You can launch your application in the simulator directly from within the Visual Studio through the debugging action. Then you can interact with your application using the mouse or using simulated touch on your development computer with gestures like swipe, pinch to zoom and rotation. Visual Studio also provides a unit test library project for Windows 8 applications written in C#, VB.net or C++.
Elisabeth Hendrickson shares her experiences and lessons learned about how testers can play well and succeed on Extreme Programming (XP) teams. One of the things testers often notice about XP is that there is no defined role for testers on the team. Yet XP teams describe themselves as “test infected”. They practice Test-Driven Development (TDD), writing executable unit tests before writing the code to be tested. Many teams practice Acceptance Test-Driven Development (ATDD), writing executable acceptance tests before implementing a feature. They use continuous integration to give them rapid feedback about the effects of changes. They practice pair programming, a technique that results in all code being peer reviewed before it’s checked in. In short, XP teams test continuously from the very first moment of any given project. You could even call them “test obsessed”.
Adobe Shadow is a new tool currently developed by Adobe that provides developers a way to inspect and debug from their desktops wirelessly and synchronously across multiple devices. The Adobe Shadow desktop application listens for changes in a URL location in the browser. When a change occurs, it pushes the new URL out to all wirelessly connected devices immediately so the changed content is seen on the devices immediately. In this blog post, Holly Schinsky provides step-by-step instructions on how to use Adobe Shadow to inspect and debug your mobile code.
There are solutions which provide the ability to automatically run your tests as you code. This tutorial shows how to use a Ruby gem, called watchr to monitor your code and automatically run the appropriate tests whenever you save your work. This is how you can automated Test-Driven Development (TDD) on your PHP code. The watchr gem is an executable program written in Ruby, and it wraps around features found in an operating system’s file system to provide the ability to watch for changes made to a specific file or folder. The tutorial provides a step by step approach on how to use it and integrate it in your PHP coding activities.
The new Visual Studio 2012 tries to improve the developer unit testing experience, particularly for agile teams. The entire unit testing framework has been made extensible, which will allow you to use testing frameworks such as xUnit.net and NUnit in addition to the unit testing framework built into Visual Studio. This talk presents the history of unit testing in Visual Studio and then takes you through the product, showing off the new unit testing features.
You might want to begin by choosing the tool you want to use when you want to introduce ATDD to a project or client. In this article, Markus Gaertner says that this doesn’t work and shares his advice on how to overcome the biggest mistakes from the beginning when you get started with ATDD. He recommends to start with an example. Working together, the team identifies a case that would derive the greatest benefit from being automated. You should define the right approach first, the right people second, the right format third. The format we choose will limit the choice of the tool, but the tool itself should be our last consideration. Instead of thinking about the tool, we should work for clarity in how we write down our examples. All the successful teams he has worked with on ATDD shared one thing: they started with one approach, and they reflected on it regularly. During those retrospectives, they came up with necessary improvements if the approach stopped working for them. If you keep this practice in mind, you can essentially start with any approach.
This blog post explains how to perform unit testing of MySQL stored procedures. A stored routine is a set of SQL statements that can be stored in the server. Once this has been done, clients don’t need to keep reissuing the individual statements but can refer to the stored routine instead. To perform unit testing on stored procedures, you can use utMySQL, an open source unit test framework for MySQL stored procedures. This post provides a step by step process on how to create the test code in utMySQL which is also a stored procedure, run it and verify the results.
