A case study explores the Streaming company's journey of building automated testing layers within a complex, multidimensional React monorepo and achieving quality contribution feedback within minutes.

Zattoo is a streaming service that develops multiple projects that serve almost all possible technologies that could play video. It is customizable for dozens of white-labeled customers and scales to hundreds of unique end-user applications. With multiple teams contributing daily and regular release cycles, our biggest challenge is ensuring fast, reliable, and maintainable quality assurance across the entire codebase.

This talk details how we transformed our approach to testing, moving from a labor-intensive, manual acceptance process to a fully automated quality feedback loop that provides results in less than three minutes for every contribution.
