AutoFixture/AutoFixture
Aug 2014 - Jun 2016
AutoFixture is an open source library for .NET designed to minimize the 'Arrange' phase of your unit tests in order to maximize maintainability. Its primary goal is to allow developers to focus on what is being tested rather than how to setup the test scenario, by making it easier to create object graphs containing test data.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:54 commits, 5 PRs, 63 comments in 1 year 10 months
Contributions summary:Diogo's contributions primarily focus on enhancing the AutoFixture library, specifically within the AutoMoq extension. The user implemented a `SealedPropertyInitializer` to handle sealed properties and fields within mock objects. Furthermore, they added a `VirtualMethodInitializer` to automatically set up virtual methods, ensuring that return values are correctly resolved from the context, along with various unit tests to validate the implemented features. The user also refactored and optimized the code base to address code analysis issues and ensure better quality.
