Consequently, testers have a responsibility to make sure they are testing the same contract that was established when the API was first released. Here's how to test APIs right.

Thought leaders from the software community are taking over the TechWell Hub to answer questions and engage in conversations. Arthur Hicken and Aprajita Mathur each recently hosted Slack takeovers, and they talked about keeping IoT devices secure, onboarding new test team members, and what skills we should be learning.
