Chaining API Tests to Handle Complex Distributed System Testing

  🔭 Tracetest - Build integration and end-to-end tests in minutes, instead of days, using OpenTelemetry and trace-based testing.

  

​ By using your observability infrastructure, Tracetest allows you to build complex and deep system tests in a simpler way. It uses declarative language that helps you create assertions against the behavior of an API more quickly. ​ With transactions, you can chain tests and check how APIs work together to determine if they are working as intended, providing valuable feedback to the teams that maintain those APIs. ​ Recently, at Tracetest we started using transactions to test our own engine, making a sequence of tests to guarantee that each feature is working effectively. You can see more details about our implementation of transactions here. ​ Ready to build more complex chained tests against your microservice-based app? Download and install Tracetest into either Docker or Kubernetes, select what trace data store you are using to collect and store your distributed traces and get started in just 5 minutes. ​ The Tracetest team is eager to hear from you - reach out to us in our Discord channel or create a GitHub issue for any additional capability you need. If you like what we are doing - please give us a star at github.com/kubeshop/tracetest!

  This repository contains the OpenTelemetry Astronomy Shop, a microservice-based distributed system intended to illustrate the implementation of OpenTelemetry in a near real-world environment.

  

​ By having an observability infrastructure gather information about a set of API/microservices, we can have a concise view of the operation of these services and start thinking in an observability-driven way to test your software. ​ Tracetest can help. When given an API endpoint, Tracetest checks observability traces to see if this API is behaving as intended. ​ For example, let’s try to test an OpenTelemetry Astronomy Store which has the exact same use cases that we want to check. ​ To test the "Add product to the shopping cart" task, we can create a test, define a URL and payload in the trigger section that we send to the Cart API and use the specs to define our assertions, checking if the API was called with the correct Product ID and if this product was persisted correctly. ​
