Fake Filler is the most popular browser extension for software testing and QA, allowing you to populate dense forms instantly with dummy data. While most developers only click the extension icon to blindly fill text boxes, there are powerful, hidden features buried within its customization engine.
Unlock the full potential of your form testing workflows with these top 10 advanced, underutilized capabilities. 1. Trigger via Keyboard Shortcuts
Bypass the mouse entirely to execute your testing data entry seamlessly.
Use Ctrl + Shift + F on Windows or Cmd + Shift + F on Mac to run the tool instantly.
Configure custom keys by visiting your browser’s native extensions shortcut menu. 2. Regex-Driven Data Generation
Enforce strict formatting validation rules instead of letting the extension output standard random characters.
Input your own regex strings into the Custom Fields matching tab.
Auto-generate string patterns that match specific parameters like employee IDs or complex alphanumeric sequences. 3. Attribute-Specific Matching Order
Control how fields match by understanding that attributes like type=“tel” always override text names.
Arrange your custom field match phrases from most specific at the top to most generic at the bottom.
Strip punctuation natively: names like user[1].first_name convert internally to userfirstname for easy target string matching. 4. Password Uniformity Enforcement
Stop dealing with randomized password inputs that make logging back into test accounts impossible.
Toggle the custom password block settings inside the extension’s configuration dashboard.
Set a static baseline password so that every randomized form submission still creates a known login credential. 5. Multi-Profile URL Routing
Isolate different data behaviors depending on which local project or client environment you are browsing.
Build separate data templates mapped directly to URL-specific custom fields.
Prevent staging environment parameters from leaking into production testing forms. 6. Dynamic Dropdown Whitelisting
Restrict selections to exact dropdown criteria rather than letting the tool select randomly.
Open your field criteria settings to activate options management.
Create a blacklist or whitelist of options for specific HTML menus. 7. Native Cloud Syncing
Eliminate manual settings transfers when swapping between your desktop, laptop, or different browser engines.
Log in via the Pro settings layer to instantly activate data synchronization.
Keep your comprehensive regex patterns and target matching rules unified across every workstation automatically. 8. Intentioned Ignored Fields
Prevent the extension from corrupting secure blocks or running on elements that break layouts.
Add specific IDs, classes, or names to the Ignore List panel.
Ensure the tool respects custom constraints while natively skipping CAPTCHAs, read-only parameters, and hidden values. 9. Custom Min/Max Length Adjustments
Stress-test boundaries of textareas and string containers without writing manual text entries.
Change the standard string generator criteria parameters inside the options console.
Force the algorithm to hit maximum length bounds (maxlength) to ensure layouts do not break when users input massive data chunks. 10. Automated Checkbox & Radio Selection
Simulate comprehensive button selections across long survey frameworks or terms-of-service conditions.
Adjust checkbox toggle rules in your preferences to force auto-checking or set random selection weight percentages.
Bypass missing-validation alerts that typically halt form processing.
