I will be giving a talk on ‘Testing All The Way To Production’ at Velocity Europe conference in London on November 14. The talk will describe how LMAX Exchange safely release to a production system processing $10 billion a day, confident that everything will be working when the markets open, and highlight some of the lessons we’ve learned along the way.
