(This article will be split into multiple parts since it would be too long) Writing correct benchmarks is hard, and it's a craft. Benchmarks try to test a piece of code running in isolation which is very hard, and the results will be mainly in milliseconds or even in smaller units of time. Consider how hard it is to measure such timings correctly and filter out the noise and other system components running at the time that might contribute to the benchmark result. Performance Testing APIs or Large s...

In the “classical unit tests” developers quite often use Arrange/Act/Assert comments to annotate the main parts of the test method script. However, the test case scenarios in component tests tend to be more complex and those simple notations don’t fit anymore. Here's my proposition on how to deal with that problem...

With the simple tricks, you can make your Docker image less cluttered and build faster. In my recent article, I explained practical patterns on how to do that. I showed real-world samples with .NET and NodeJS applications.

Richard July 28th, 2021 Open source was an attractive and exciting idea when we first considered sharing .NET Core on GitHub. At the same time, GitHub was a largely unknown platform for many of us and we had a lot of questions about how everything would work. “What if someone forks the runtime on the first day? Is the project over?”. We knew enough that we should take the time to learn the patterns that developers had already established and also what they expected of us. That said, we also had to host...

Cake allows to write C# scripts for compiling code, running unit tests, copying files/folders, etc. There is built-in support for many tools and many more via addins. In these post series I will show how to create Cake script that can: run unit tests, build Xamarin app, deploy app to App Center, deploy app to Google Play Internal, deploy app to Test Flight, run UI tests. The script can be used in every Xamarin app. I will also show how to create Azure Pipeline that use Cake script.

Seriously, you may not understand how things work under the hood but still write code and remain easy-going about this. Though you still have to deal with different nuances over time. Today, we'll look at one of suc...

Jak przekazać kontekst? I co w ogóle oznacza kontekst? I dlaczego Dependency Injection nie zawsze jest odpowiedzą. Zapraszam.

When I started my career, SQL Injection and Cross-Site Scripting were perceived as sophisticated attacks. Mature admins installed MSSQL servers with the Internet turned off, because by default, open to the world was a potential source of the attack. Setting up the firewall wasn’t even a standard. Today we have easier. By using the cloud, many things are warranted. Suppliers protect us from basic break-ins. For instance, they’re blocking DDoS attacks and many other attacks that we don’t even know existed...
