The UsabilityHub (https://usabilityhub.com/)tool allows you to create three test types:
- Five seconds test: the layout is shown to a user for five seconds and then he answers a series of questions about what he saw
- Click test: the layout is shown to a user next to a task, and the system records which region of the screen is clicked
- Nav flow test: you upload a series of images and test if people can complete certain flows of navigation
