Aviad Ezra on Software Architecture. Friday, December 3, 2010. Component Testability KILLERS (and suggested solutions). Since system quality depends on component quality, any defective component causes a ripple effect throughout systems that include that component. Hence, validation and quality control of isolated components is crucial for producing quality systems. In order to validate component quality, we must follow a cost effective. And usually developed by test engineers. Black box test methods...

Aviad Ezra on Software Architecture. Sunday, November 7, 2010. Testing with Managed Extensibility Framework (MEF) for Silverlight. In the previous post. We developed test strategies for a three tiers, MVVM based Silverlight application. Which uses the Managed Extensibility Framework (MEF) in order to loosen the coupling between the components and to provide better testability and extensibility. To MEF or not to MEF (during tests)? However, in some cases, the tested functionality uses MEF in order to prov...

Aviad Ezra on Software Architecture. Sunday, October 24, 2010. Developing Silverlight 4.0 App with MVVM and MEF. In the previous post. We walked through the process of developing three tiers web app using Silverlight 4.0, MVVM and WCF Data services. In this post, we’ll see how we can take advantage of the new Managed Extensibility Framework (MEF) for Silverlight. In the next post. Any of its parts (classes) to other components, and to import. External parts from any component in the xap boundaries. In a ...

Aviad Ezra on Software Architecture. Sunday, May 11, 2014. Testing in Production – Benefits, Risks and Mitigations. Testing in Production (TiP) is the most important mind-shift required for building and operating a successful service at scale. This post outlines the benefits of Testing in Production, walks through the methodologies and explains the practices that can be applied to mitigate the associated risks. How much testing should we do in production? Implementing these methodologies is not easy to s...
