Test Data Generator & Dummy Data Filler

Use Test Data Generator to auto fill web forms with dummy data.

🧪 Test Data Generator is a lightweight chrome extension that fills any web form with realistic fake data in one click. Stop typing sample values by hand — let the test data generator auto fill forms while you focus on the real checks. ⚡ It is built for developers, QA engineers and testers who fill the same forms dozens of times a day. Whether you work on a signup page, a checkout flow or a long survey, this tool populates every field instantly. 🚀 How to generate test data in seconds: 1. Install the extension from the chrome web store. 2. Open any page that contains a web form. 3. Press the hotkey or click the icon. 4. Watch the generator fill names, emails, phones and addresses at once. ✨ What this generator can create for you: ➤ Random names — first, last and full names for any profile field. ➤ Fake email addresses that pass basic validation. ➤ Phone numbers in local and international formats. ➤ Street addresses, cities, zip codes and postal codes. ➤ Dates in ISO, US and EU formats for any date picker. ➤ Credit card numbers that pass checkout validation. ➤ UUIDs and reference codes for technical or hidden inputs. ➤ Dummy text for comments, bios and message boxes. 💡 Why teams pick this test data generator - It removes the boring part of the job: no more inventing sample values by hand. - It can generate test data that looks real, so your forms behave like they do in production. - It works on any site — the web form filler detects fields automatically. 🧩 Smart field detection 1️⃣ The extension reads each input and picks a matching value type. 2️⃣ Email fields get fake email addresses, phone fields get valid numbers. 3️⃣ Checkboxes, radios and dropdowns are filled too, not just text inputs. 🎯 Everyday scenarios where test data generation helps: ▸ Fill a registration form to test validation rules. ▸ Populate a checkout page with credit card numbers and dummy values before a demo. ▸ Generate test data for a staging environment through your admin panel. ▸ Speed up manual QA when you run the same web form again and again. ⌨️ Built for speed - Assign your own keyboard shortcut and fill a whole page without touching the mouse. - Right-click any single input to fill just that field. - Use the toolbar icon when you prefer a click over a hotkey. 📌 A real time saver for QA teams ➤ Manual typing is slow and error-prone. This test data generator removes it completely, so every form is filled the same way on each run. Your test data generation becomes repeatable, and bug reports get cleaner because the input stays consistent. 🐞 QA mode: the same data on every run A form filler for QA testing has to do more than type random values. When a bug shows up, you need the exact same input again, and your teammates need to see what was filled. 🔁 Reproducible fills ▸ Every fill has a seed. Click "Refill with same data" in the popup to get the same values again. ▸ Lock the seed with the lock icon to keep it for the next fills, so a failing case stays reproducible until the bug is fixed. ▸ Each value depends on the seed and the field itself, not on field order, so a changed layout does not shuffle your data. 📋 Fill log for bug reports ▸ "Copy fill log" copies a Markdown table of every field and value, with the seed on top. Paste it into Jira, Linear or GitHub, and anyone can repeat your steps with the same input. ↩️ Undo and a safe shortcut ▸ Every fill can be undone: click "Undo" in the notification, use the undo button in the popup, or choose "Undo last fill" in the right-click menu. ▸ "Fill all fields on this page" leaves text you typed outside a form alone, so notes, timesheets and documents in web apps are not overwritten by an accidental shortcut. 🖱️ Field rules from the right-click menu ▸ Right-click a field, choose "Remember this field as", and pick a data type, a fixed value, a template, or skip the field. ▸ A rule works on one page or across the whole site, and it takes priority over automatic detection. 🧨 Edge cases for validation testing ▸ Right-click a field and choose "Insert edge case": one character over the length limit, 10,000 characters, Unicode and emoji, right-to-left text, leading and trailing spaces, an empty value, number limits, an invalid email or phone. ✉️ Templates for unique test accounts ▸ Set patterns such as qa+{seq}@yourcompany.com or test_{date:yyyyMMdd}_{seq}. The counter grows with each fill, so every signup gets a fresh test email. 🗂️ Profiles for every test scenario ▸ A profile keeps its own locale, templates and fill options. Pick it in the popup or in the right-click menu. The first three also get keyboard shortcuts: Ctrl+Shift+1, 2 and 3. ▸ Right-click a filled form and choose "Save this form as profile" to fill it with the same values later. Turn on "Use on any site" to reuse it on your dev and staging copies. ▸ "Skip filled fields" keeps what is already on the page, so you can type a few values yourself and let the extension fill the rest. Checkboxes and dropdowns can be switched off too. ▸ Two ready-made modes, "Edge cases" and "Invalid data", fill the whole form at once with boundary values or with values a form should reject, such as user@ or February 31, so every validation message shows up in one pass. 📊 Data-driven testing with a CSV file ▸ Import a CSV file, and each fill takes the next row. The popup shows which row comes next, with arrows to go back or skip ahead. ▸ A column fills the field with the same name. Give a column a data type, and one "email" column fills every email field on the page. 📤 Share your setup with the team ▸ Export profiles and field rules to a JSON file and import them on another computer. Importing adds to what is already there and replaces only the matching ones. ✅ Fewer false failures ▸ Confirm email and Confirm password fields match the main ones, and the gender field matches the name: one made-up person per form. ▸ Custom dropdowns from popular UI libraries are opened and an option is picked, the same way a person does it. Multi-select lists get several options, and the extension waits for lists that load their options from a server. ▸ Rich text editors, file upload fields and inputs with a pattern or step get values that pass validation. ⚙️ Profiles, field rules, templates and your last 10 fills are managed on one settings page and stay in your browser until you export them. 🔒 Private by design - The extension works locally in your browser. - It does not send your forms or the generated values to any server. - Nothing you fill is tracked. Your last 10 fills are kept only in your browser, for the fill log. 🌐 Works everywhere you test ▸ Internal admin panels and dashboards. ▸ Public signup, login and contact pages. ▸ Multi-step wizards and long surveys. ▸ Any custom web form your team builds. 🔤 Fits the market you ship to ▸ Locale-aware names, cities and phone number formats. ▸ By default the locale follows the language and domain of the page. Switch it in the popup when you need another one. 🛠️ A flexible alternative to heavy test data generation tools 1. Fill a single field, one section, or the whole page. 2. Re-run the random data generator as many times as you like. 3. Combine fake names, fake emails and dummy text in one pass. 📈 Faster testing, better forms When you generate test data automatically, you catch layout and validation issues sooner. A quick web form filler means more runs in less time, and more runs mean fewer bugs shipped. 🧐 Frequently asked questions ❓ What is a test data generator? 💡 It is a tool that creates realistic fake values for you. This one works as a browser extension: it auto fills any web form with names, emails, phones and addresses, so you never type sample records by hand again. ❓ What is test data generation? 💡 It is the process of creating sample records for testing instead of using real customer details. A dummy data generator gives your team safe, repeatable input for every run. ❓ How to generate test data on a page? 💡 Open the form, press the hotkey, and the extension fills every field at once. You can repeat it as many times as you need. ❓ Is the generated information real? 💡 No. Every value comes from a random data generator, so it looks realistic for testing but does not belong to real people. ❓ Which fields can it fill? 💡 Text inputs, email and phone fields, addresses, zip codes, dates, credit card numbers, UUIDs, dropdowns (including custom and multi-select ones from UI libraries), checkboxes, radio buttons, rich text editors and file upload fields. The form filler detects each field type on its own. ❓ Can I undo a fill? 💡 Yes. Click "Undo" in the notification after a fill, or use "Undo last fill" in the popup or the right-click menu. The previous values come back. ❓ Can I fill a form with my own data? 💡 Yes. Save a filled form as a profile, or import a CSV file where each row is one set of values. Each fill takes the next row. ❓ Do I need an account? 💡 No sign-up is required. Install it and start filling forms right away. ❓ Is my information safe? 💡 Everything runs locally in your browser.
