About Testofill, Form Filler for Testers

Testofill allows you to define one or more sets of rules for filling forms on a particular page and to fill them in automatically or on demand with hardcoded or random values. It targets people that can write little CSS (such as "[name='myfield']"), are comfortable with JSON, and that need to be able to choose from sets of values to fill in. A typical example is a tester that needs to repeatedly fill in different search criteria to test her app and thus wants to define rule sets such as "Simple book search" and "Advanced book search". The main advantages are being able to have multiple sets of values for a single form, having full access to and control over these values, and ability to generate random values. It is also possible to create rules automatically from a filled form and adjust them later. See a short demo here: https://youtu.be/iDkSwpKd3NQ Tip: You need to enable the extension in Incognito mode on the Extensions page if you want to be able to use it when Incognito.
