Yeah I’ve lost countless hours to build pipelines.
Custom images/runners is the way to go. Basically docker image that runs your pipeline scripts. Then you have much more control over things.

You write tests. But are they helping you and your team?
In this .NET Rocks! episode, @egilhansen.com explores how to make tests more durable, insightful, and future-proof. Plus: should AI be writing your tests? 🤖 #dotnet

They will be very useful in source generator scenarios.

Suffering for your friends I see 🙂

Oh ffs. Spelling is hard. Pleasure. It’s a pleasure 😆

Always a please chatting with Carl and Richard on their podcast!

You write tests - but are they valuable tests?

@EgilHansen.com talks on .NET Rocks at www.dotnetrocks.com/details/1971 about his approach to building tests for applications!

I am more thinking about what to snapshot test and what not to snapshot test.

E.g., a rule I try to follow is to not include irrelevant (to the test) data in the snapshot, as it makes it harder to validate the snapshot when it changes.

Egil Hansen @egilhansen.com · May 2

@simoncropp.bsky.social do you have a list of does and donts in snapshot testing somewhere? Examples of good patterns and anti patterns with Verify?

If the facts are as the article lays them out, I hope one of my friends from #microsoft will make this right. Adherence to OSS licenses is important!

Yep, saw this live. Huge respect for people that dare to be vulnerable; it’s such a powerful thing.

Need a cure for that primitive obsession in #dotnet? Take a look at www.nuget.org/packages/Egi...

First real attempt at a source generator library. Happy with the result. A key feature is that it’s very easy to overwrite the default generated code, just as it is with C# record classes and structs.

Egil.StronglyTypedPrimitives 1.9.7

A source generator for creating strongly-typed primitive types that makes it easy to avoid the primitive obsession anti pattern. Add a [StronglyTyped] attribute to a partial record struct ...

Going live with @steven-giesel.com for the first #bUnit dev session of this month. We may even get a visit from @scottsauber.com :)

Join at twitch.tv/egilhansen and www.youtube.com/watch?v=jZrZ...

Egil Hansen @egilhansen.com · Mar 28

Congrats Scott. You are living the dream!

Egil Hansen @egilhansen.com · Mar 10

This could be said about the internet in general.

Mike Ginn @shutupmikeginn.bsky.social · Mar 8

its amazing how chatgpt knows everything about subjects I know nothing about, but is wrong like 40% of the time in things im an expert on. not going to think about this any further

Egil Hansen @egilhansen.com · Mar 7

Hey folks, @steven-giesel.com and I just went live with another #bunit dev session. Come hang and lets build v2 together.

Actually, I think I usually do a `git clean -fdx` for a "reset the world" operation.

Egil Hansen @egilhansen.com · Mar 6

There is a git command that does it, just can’t remember it when I need it, so have to search the web. If your tool had a -all option that would be great 😊

Egil Hansen @egilhansen.com · Mar 6

Could it also have an option that does the same a clean git clone?

Sometimes deleting e.g., the .vs folder helps with weirdness in vs.

Egil Hansen @egilhansen.com · Mar 3

By using Aspire and related client libraries you get basic telemetry out of the box (without solution specific context), so I’ll do that and then add some/few end-2-end tests for basic protection against regressions.

Egil Hansen @egilhansen.com · Mar 2

Solve different problems, so it’s like comparing apples and oranges.

Egil Hansen @egilhansen.com · Mar 1

@captainsafia.com does (or will) #dotnet's OpenApi generator have a way to declare a custom schema transformer for type as an attribute, like we can with JsonConverter?

E.g.:

[OpenApiTransformer()]
public record MyId(int Value);

It’s not trivial for sure.
