QuestionIs a separate view model relevant for Blazor server side given that we can test the whole component with bUnit? Pin

When writing software, whether desktop or web-based, I have always separated the view from the view model. For example, in WPF (Microsoft desktop technology), I used MVVM, kept the XAML view as light as possible and put the logic and data access into a separate view model (regular C# class).

One of the main advantages of this is that it makes the view model easy to unit test, as I can set up mock dependencies, set the public properties that would normally be set by dependency injection or property binding and then call methods no the view model to test the code.

Nowadays I do pretty much everything in Blazor server-side, and used the same approach. My .razor file is pure markup, the .razor.cs file usually only contains overloads for the component life-cycle events, and generally passes the request through to the view model (as above).

However, one of my co-workers is encouraging the team to put all code into the .razor.cs file, and use bUnit to unit test the components. Given that we can mock dependencies, set public parameters and call methods, it does look as if this gives all the benefits of a separate view model, without needing the extra file.

Anyone any thoughts as to the advantages or disadvantages of either approach? Thanks
