Assessing Risks in the Scrum Framework

Software Risk Management (SRM) combines a set of tools, processes, and methods for managing risks in the software development lifecycle. In SRM, we want to make informed decisions about what can go wrong at various levels within a company (e.g., business, project, and software related).

What Agile Testing (Actually) Is

So, now that the first installment of this two fold article has been published (hence you might have an idea of what Agile Testing is not in my opinion), I’ve started feeling the pressure to explain what Agile Testing actually means to me.

A Detailed Guide To Xamarin Testing

Xamarin is an open-source framework that offers cross-platform application development using the C# programming language. It helps to simplify your overall development and management of cross-platform software applications.

Options for Manual Test Case Development & Management

The purpose of developing test cases is to ensure the application functions as expected for the customer. Test cases provide basic application documentation for every function, feature, and integrated connection. Test case development often detects defects in the design or missing requirements early in the development process. Additionally, well-written test cases provide internal documentation for all application processing. Test case development is an important part of determining software quality and keeping defects away from customers.
