And, bUnit provides a mock NavigationManager to allow test code to request a navigation without actually performing it. Under our test … Continue reading How-To: Verify Blazor Navigation in bUnit →

How-To: Use Class File for Blazor Logic Code

As our logic continues to grow and our testing requirements increase, we will find that it is more efficient to separate our application logic from the rendering logic on pages. This split helps us separate these concerns and build cleaner pages. Also, having the logic within a separate C# class allows us to unit test … Continue reading How-To: Use Class File for Blazor Logic Code →

How-To: Use Blazor Code-Behind File

In Blazor, sometimes our page code becomes large and cumbersome. Rather than keep all of the HTML markup and C# code in the same .razor file, we can split our markup and code into separate files. Blazor supports creating code-behind files for the .razor file (similar to other .NET technologies like WinForms, ASP.NET, WPF, etc). … Continue reading How-To: Use Blazor Code-Behind File →

How-To: Write bUnit Tests for Components with EventCallbacks

Component callbacks allow developers to build Blazor components that fire events to their parent components/pages to notify them of state changes. The parent components can then respond to those changes as well. bUnit supports EventCallbacks as parameters on those components, so that we can validate their behavior. First, we must have a Blazor project and … Continue reading How-To: Write bUnit Tests for Components with EventCallbacks →
