Testofill is a free Chrome extension developed by Jakub Holý. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

Testofill is designed to enable testers to fill forms automatically or on-demand based on sets of rules they have written or captured. It allows users to define one or more sets of rules for filling forms on a particular page and fill them in with hardcoded or random values. This extension is ideal for individuals who have basic CSS knowledge and need to repeatedly fill in different search criteria for testing purposes.

One of the main advantages of Testofill is its ability to have multiple sets of values for a single form. Users have full access and control over these values and can even generate random values. Additionally, Testofill allows users to create rules automatically from a filled form and make adjustments as needed.

To use Testofill in Incognito mode, the extension needs to be enabled on the Extensions page. It is also recommended to only allow the extension access to the specific sites where it will be used for security purposes.
