Crowdsourced testing is a great way to connect with users and ensure that the product idea, design, implementation, and nonfunctional elements meet their expectations—or, hopefully, even exceed them. But like any other test effort, crowdsourced testing is both a science and an art. Here's how to do it effectively.

To advance the technology needed to create sustainable housing solutions for trips to the moon, Mars, and beyond, as well as here on Earth, NASA is conducting the 3D-Printed Habitat Challenge. Teams compete to construct dwellings out of local, indigenous, or recyclable materials, and designs are out of this world.

Test design can contribute greatly to how manageable and maintainable your automation is. Hiding detailed steps in actions makes their automation easier to maintain, and the high-level actions can be leveraged to define less common tests. Here's how you can write tests as a sequence of actions to improve coverage.
