I am an expert software engineer with over two decades of experience who is driven by passion for technology. I specialize in Kotlin and cloud-native solutions and focus on building mission critical, scalable and maintainable systems. Besides software development I also enjoy sharing my knowledge through talks, my blog, giving Kotlin training, and as the book author of “Kotlin Crash Course”, a project-based approach to learning Kotlin from scratch, growing your skills from the basics to advanced concepts. My work has been featured in newsletters such as Kotlin Weekly, JetBrains Blog, Android Weekly, Serverless Advocate, and Dear Architects.

Simplifying Serverless Integration Testing: WireMock on AWS Lambda

Room: Room 2 | Time: 11:00 | Duration: 30

In serverless architectures, integration testing becomes a key focus in the testing pyramid, as local environments cannot fully replicate the complexities of cloud deployments. External APIs, often unavailable or difficult to configure, pose a significant challenge during testing. Mocking external APIs locally with tools like WireMock is common, but to truly validate serverless applications, testing must occur in the deployed environment. This talk explores how to leverage WireMock on AWS Lambda to mock external APIs directly in the cloud.
