In my journey through the nuances of API testing, I’ve often encountered the challenges and time-consuming aspects of creating accurate WireMock mappings. As developers, we often get bogged down in the details of the anatomy of inter-service communication, not to mention the frustrating typos that lead to inaccurate mappings. In this blog post, I will introduce a powerful solution: the WireMock.NET proxy. This feature completely changes the way we approach mapping preparation, significantly reducing both workload and debugging time. ... Read More

GraphQL is a query language for APIs that allows clients to request exactly what they need, making data retrieval more efficient than traditional REST APIs. It supports three different types of client-server interaction: queries, mutations and subscriptions. When you start integrating a GraphQL API as a consumer in your application, it’s likely that you’ll need to write automated tests to ensure that the integration works correctly. In this blog post, I will show you how to mock GraphQL queries using WireMock.NET.

As .NET developers, we understand the significance of writing automated tests to ensure our applications function correctly. However, as our applications grow more complex and diverse, optimizing the test process becomes crucial. One effective approach is reusing components like tested application and WiremockServer instances between test cases. While this optimization can improve test efficiency, it can also introduce challenges of ensuring that different test cases do not interfere with each other. ... Read More

In the world of Kubernetes and microservices, diagnosing and debugging issues can be a challenging task. One powerful tool in your troubleshooting arsenal is memory dump analysis. Memory dumps capture the state of an application’s memory at a particular point in time, providing insights into potential issues, bottlenecks, and crashes. In this blog post, I’ll walk you through the process of collecting a memory dump from a .NET Core application running on Kubernetes. ... Read More
