This talk was presented in our Criteo DevXDays 2022 edition.

How do you face a good testing strategy in the microservice era? But, wait, do you even care about testing? We hope you do :)

Let's face it, we learn about architecture, best practices, design patterns and other fancy developers' tools but testing strategy is left behind. Unless we are in a team where testing is a core value (e.g. through Test First methodology), we tend to use the chameleon rule and don't challenge the testing strategy.

Join us in this talk to discover our testing developer toolbox (yes, writing tests is dev): unit tests, isolation testing, consumer-driven contract testing, backendless tests, property based testing, BDD, mutation testing, system under test builder … and how we use these tools to build an efficient testing strategy in the microservice era.

And, of course, feel free to share your insights in the comments!
