C# tricks – Debugging Complex Classes with the [DebuggerDisplay] Attribute

Debugging complex trees of objects can be difficult even with great debugging tools. In order to make it easier on yourself, consider adding the DebuggerDisplay attribute to those difficult-to-debug classes. DebuggerDisplay allows you to provide a view of your object in the Visual Studio debugger windows that have exactly the data you need to see in order to fix your problems.

How to debug Angular component test Dependency Injection chain

When running ng test (Angular component testing) and you get this type of error:

[Service1 -> Service2 -> Service3]: NullInjectorError: No provider for Service3!

And you dont really understand which component, service or directive that is starting this DI chain. Here is a way to debug and hopefully find the source of the problem:

In Edge/Chrome: when in karma runner page, open devtools (f12), on source tab, select both “Pause on uncaught/caught exceptions”

Reload the test, step into a few times, you should be able to get the call stack as in picture above. Here we can deduce that DI chain starts with a component html template, which uses a translate directive in markup, which calls DictionaryService which calls UserAppDataQueryService which calls AuthenticationService.

Tip: run all spec files below a certain folder like this:

ng test --include "src/app/myarea/**/*.spec.ts" --browsers=Edge

Tip2: run a single spec file:

ng test --include "src/app/myarea/**/mytest.component.spec.ts" --browsers=Edge

Angular and Wiz Are Better Together

You may know Angular as the web framework from Google, but Google actually has another web framework: Wiz. Both Angular and Wiz are used by thousands of engineers and thousands of apps inside of Google. Wiz is an internal framework that is used by some of the most popular Google products such as Search, Photos, Payments and many others. Over the last year we’ve been exploring ways for Angular to benefit from the performance of Wiz and Wiz to benefit from the developer experience of Angular.

This is particularly true in the .NET ecosystem, where projects often rely on a vast array of NuGet packages.
