Trace-Based Testing with OpenTelemetry
Distributed tracing allows devs to find and fix issues in production after they happen. There is another use case for tracing data: trace-based testing. We can improve assertion capabilities by leveraging OpenTelemetry trace data and making it accessible while setting our expectations from a test.
Companies these days use distributed tracing for critical functions such as performance monitoring and troubleshooting, allowing DevOps, developers, and SREs to find and fix issues in production after they happen. But here is the thing, they don’t use tracing to its full potential.
There is another use case for tracing data, and that is trace-based testing. This new method allows you to improve assertion capabilities by leveraging traces data and making it accessible while setting your expectations from a test.
We will introduce you to a new open-source called Malabi - a Javascript framework based on OpenTelemetry that allows you to easily use trace data to take your assertion capabilities to the next level.
By the end of this session, you will know how to use trace-based testing to increase your tests’ reliability and possibly prevent issues early in the development cycle.
