Contemporary software systems are often built on a microservices architecture pattern. In this pattern, rather than build one huge code-base for a single application, systems are separated into multiple smaller code-bases. These implement services that provide a specific feature, like authentication or monitoring, and those services can have performance problems, network issues, or bugs in their code – any of which can lead to failing tests. If you want to solve such problems, you have to go a step further than just logging your errors – it is best for you to monitor your tests with distributed tracing. This talk will show you why a tracing system will rescue you from the complexity of understanding why an E2E test has failed in a distributed architecture.
Why Tracing is a Lifesaver for E2E Tests of Distributed Systems?
