Learn how to test with Spring Cloud. With many industries transforming to a microservices architecture, testing these microservices is a challenge.

Whether it be for design purposes or for marketing purposes with social media, knowing how to get a screenshot of your HTML design without manually taking the screenshot can be a great thing.

In September I joined Engineering Operations at Tasktop as a Senior Software Engineer, helping the company to drive improvements in our builds, monitoring, infrastructure automation, release engineering, and all the other great things the team does. However, like many of my colleagues, my path to Tasktop was anything but conventional.
