• How to test asynchronous components of your application
• How to test whole applications for resilience, scalability, and responsiveness

Next to all client-side concerns such as browser compatibility and execution on a plethora of mobile devices under varying connection speeds and connection quality, we must also concern ourselves with the guarantees that a reactive web application promises to deliver—being able to react to load by scaling out (and back in), offering a degraded execution rather than complete outage under failure, as well as responding ...
