This workshop will get you started on the right track and teach you all the best practices you need to know to write clean and effective unit and integration tests in .NET with C#. 

It will also introduce you to the concept of performance testing and get you started with testing how your applications perform when pushed to their limits.

- Understanding the different types of testing
- Introduction to Unit testing
- Mocking
- Fakes
- Assertions
- Creating test data at scale
- Creating realistic test data
- Testing “untestable” code
- Code coverage
- Measuring code coverage
- The value of code coverage
- Introduction to Mutation testing

- Introduction to Integration testing
- Understanding the WebApplicationFactory
- Mocking third party API dependencies
- Building test-specific environments using Docker
- Databases
- APIs
- Integration testing Web UI
- Introduction to Performance testing
- Load testing
- Stress testing
- Soak testing
- Smoke testing

This workshop is aimed at backend developers with some experience writing applications using C# and .NET.

The workshop will not focus on .NET Framework at all and will only briefly touch on front end testing.

Visual Studio 2022 or JetBrains Rider or VS Code

Docker Desktop (no need for Kubernetes to be installed)

From Zero to Hero: Effective testing in C#

.NET

Testing

It’s 2023. .NET is a free, open-source development framework that runs on everything from Raspberry Pis to cloud data centres, server-side rendering is cool again, and despite what you might have read on LinkedIn, AI is 

 about to take away all our jobs. In this two-day, workshop, you’ll learn how to design, deliver, and test state-of-the-art web applications that harness the power of the C# language and the 

 Core platform. Alongside familiar patterns like model/view/controller and dependency injection, the latest versions of 

 Core introduced a streamlined hosting model, a new set of conventions for routing requests within our applications, and a completely new architecture known as “minimal APIs” for building API endpoints and microservices.
.NET also supports a thriving ecosystem of open source projects and packages. Entity Framework Core provides first-class abstractions over relational databases like MS SQL Server and PostgreSQL. Libraries like NodaTime can simplify and streamline your application logic. Projects like xUnit, Moq, and Shouldly let you test your applications at whatever level makes sense - from low-level unit testing to end-to-end integration tests that test your app’s entire HTTP pipeline. And on the front-end, it’s never been easier to incorporate technologies like SASS, CSS grids, responsive layouts, and even libraries like MJML for sending HTML emails.

Overview of .NET web application architecture

.NET 6 vs .NET 7 - long term support, or latest & greatest?

Deploying database changes using EF Core Migrations

Testing application behaviour and business logic

Data formatting: dates, times, currencies

Formatting data using System.Globalization

Layouts, areas, partial views, and tag helpers.

Cross-platform gotchas: what to watch out for when you’re developing on Windows or macOS and hosting on Linux

Deploying to Microsoft Azure using GitHub Actions

Application monitoring using Application Insights

This workshop is aimed at developers with some experience of the C# language, the .NET platform, and some basic web development. If you understand classes, inheritance, Console. WriteLine, and you know what the <select> tag in HTML does, then you should be just fine.


Attendees will need a computer running .NET 6 or .NET 7, Docker, and a code editor that supports .NET such as Microsoft Visual Studio 2022, JetBrains Rider, or Visual Studio Code.
