Test Data Generation

Fill any form with realistic, coherent sample data in one click. Built for QA engineers, developers and product teams who test forms all day.

Overview

Testing a signup flow means inventing a person: name, email, birthday, address, phone. Doing it dozens of times a day is mind-numbing — and typing "asdf" everywhere breaks validation. FillWise generates a realistic, internally consistent record and fills the whole form with it in one click.

Unlike static faker tools, generation is context-aware: it reads the actual form, understands each field, and produces values in the format the form expects — including valid dropdown options and checkbox states.

Key Capabilities

Capability What it means for you
Realistic records Coherent person profiles, not gibberish
Format-aware Dates, phones and numbers match each field's expected format
Valid selections Dropdowns, checkboxes and radio buttons get valid values
Partial generation Your real data stays; only empty fields are generated
Any form Works on every website, in any language

How It Works

  1. Open the form you're testing.
  2. Enable the random data toggle in the FillWise side panel — optionally add real values you want to keep fixed.
  3. Click Fill. Every empty field gets a realistic value; run it again for a fresh record.

Use Cases

Who What they test
QA engineers Signup, checkout and onboarding flows with fresh data each run
Developers Form validation and edge cases during development
Product teams Demos with realistic-looking data instead of "test test"
Agencies Client site checks before launch

Common Questions

What kind of data does it generate?

Realistic values that fit each field — plausible names, valid-looking emails and phone numbers, correctly formatted dates, matching addresses. The whole record is coherent, not random noise.

How do I use it?

Enable the "Fill empty fields with random data" toggle in the side panel and click Fill. Every empty field gets a realistic value.

Can I mix generated data with my own?

Yes. Provide the values you care about, and generation fills only the remaining empty fields around them.

Does it respect field formats and dropdowns?

Yes. Generated values follow each field's format hints, and dropdowns get a valid option selected — so the form actually passes validation.
