Visual Basic
Microsoft
FreeVisual Basic, an object-oriented programming language created by Microsoft, allows for the rapid and straightforward development of type-safe applications within the .NET framework. It emphasizes enhancing the capabilities of the Visual Basic Runtime (microsoft.visualbasic.dll) for .NET Core, marking the first iteration of Visual Basic that is tailored specifically for this platform. Future updates are anticipated to incorporate elements of the Visual Basic Runtime that rely on WinForms. The .NET framework itself is a versatile and open-source development environment designed for the creation of various types of applications. Regardless of the application type, the code and project files maintain a consistent appearance and functionality. This uniformity ensures that developers can leverage the same runtime, application programming interfaces (APIs), and language features across all their projects. A Visual Basic application is constructed using standard components, where a solution includes one or more projects, and each project can consist of multiple assemblies, which are in turn compiled from several source files. Overall, this structure enables developers to efficiently manage and build complex applications. -

MockK
MockK
FreeMocking serves as an effective method to enhance the readability and maintainability of code during testing. In a series of three articles, I aim to explore the foundational concepts, features, and unique aspects of the MockK library. This innovative open-source library, available on GitHub, is dedicated to simplifying the mocking process in Kotlin. When it comes to property injection, the library first attempts to align properties by their names, followed by matching them based on class or superclass hierarchies. For further customization, users can refer to the lookupType parameter. Notably, property injection continues to function even when private visibility is enforced. Additionally, when selecting constructors for injection, the library prioritizes those with the highest number of arguments, proceeding to those with fewer. This thoughtful design enhances the user experience and flexibility in testing scenarios.
