Last week we moved from an in-memory data store to SQLAlchemy and persist our tasks inside an SQLite database. We have two things we need to optimize, or else we end up with problems along the way. This post is part of my journey to learn Python. You find the code for this post in …
If we do not want to keep starting our API and manually click through the endpoints to see if everything still works, we need to put a little effort into testing. Thanks to the underlying Starlette toolkit, we can test our FastAPI application in-memory and do not need a dedicated server. Let us explore how …
Last week we run into a strange problem with our integration tests. On some developer machines everything worked fine, while other machines got errors like this one: System.InvalidOperationException : Cannot resolve scoped service ‘my.application.IOrderRepository’ from root provider. at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteValidator.ValidateResolution(Type serviceType, IServiceScope scope, IServiceScope rootScope) The problem It took us hours to understand what was …
If you need an API endpoint that gives you some (static) test data, you can join the search for the most complicated solution. My current favourite in unnecessary complexity is to use MongoDB to serve a handful of JSON objects. However, if you prefer a much lighter approach and already use .Net, I strongly recommend …
Since I wrote about how to migrate from Moq to NSubstitute, we decided to migrate our work projects as well. The migration was much simpler than anticipated and we got some nice benefits along the way. Search and replace We did the largest part of the migration with search & replace in Visual Studio. …
If we want to test our code, we often need files with the right format. We can create a text file without much effort, but what do we do if we need a specific video format or an audio file in OGG? Luckily, we are not the only ones with this problem. There are dedicated …
I was a happy user of the Moq library for the last 12 years. I liked the simplicity of Moq and how it allowed me to write tests first and then incrementally build the functionality. Unfortunately, the creator of Moq is currently doing his best to kill the project. As he declared, either his spyware …
If I run into tasks that I must repeat countless times, I try to automate them as much as possible. Since we always add the same dependencies to our test projects, we thought it would be a great idea to create a project template that has all the necessary settings already in place. Let us …
The code coverage is an important part of the quality metrics of SonarQube. Unfortunately, SonarQube needs some extra steps to use our code coverage reports from our Azure DevOps pipeline as part of its code analysis. As in the last posts on code coverage, we again use Coverlet and ReportGenerator as part of our Azure …
Last week we used Coverlet and ReportGenerator to collect code coverage on our development machines. In this post we continue this journey and extend our build pipelines to get a nice coverage report with every continuous integration build. Extending the test task We can collect the code coverage files in the build pipeline by …
