Working with, microservices-based development environments presents a unique set of testing challenges. Richard North developed an open source solution called Testcontainers in 2015 to help ease this problem for developers. Today, the open source project is used by companies like Uber, Netflix, Spotify and Capital One.

North and co-founder Sergei Egorov (who was a co-maintainer of Testcontainers) founded AtomicJar in 2021 to build a commercial company on top of the open source tooling. They have taken the original idea a step further by creating a cloud-based version to expand the tool’s capabilities and move some of the resource-intensive testing from a developer’s laptop to the cloud.
