Test Case Generator

Generate structured test cases from templates and automatic boundary-value cases for any field. Edit, prioritize, and export as Markdown or CSV in your browser.

1 · Start from a proven template

Templates cover the standard flows QA plans miss: happy path, negative cases, boundaries, and security checks.

2 · Generate boundary values for a field

Boundary value analysis tests the edges of every accepted range — the values that break software most often. Runs entirely in your browser.

3 · Review and edit

No test cases yet — add a template above, generate boundary values, or add a blank row.

4 · Export your test case document

Markdown pastes straight into Notion, GitHub, or Jira wiki; CSV opens in Excel and Google Sheets. Everything runs client-side — your test data never leaves the browser.

Why Test Case Generator?

Every test suite starts the same way: a blank page, and a tester writing the same ten cases again. This generator starts you from the case sets worth keeping - the wrong password, the file one byte over the limit, the double-clicked Pay button - and produces boundary cases for your specific fields, so the suite covers edges instead of vibes.

  • Load a template, then delete what does not apply - editing down is faster than writing up.
  • Boundary cases are where most bugs live: generate them for every field with a documented range.
  • Export as Markdown for the repo wiki or CSV for Excel - a test-case doc that lives with the code actually gets maintained.

What is Test Case Generator?

Test Case Generator builds a structured test case document from proven QA patterns. Start from a template for the flows every product has - login, sign-up, search, file upload, password reset, checkout, contact forms, and REST API endpoints - then generate boundary-value cases for any field with a defined range or length. Every case lands in an editable table with an ID, type, priority, preconditions, steps, test data, and expected result. Export the suite as Markdown, CSV, or a downloadable file. Everything runs in your browser; nothing is uploaded.

Common Use Cases

Starting a Test Suite From Scratch

Load the template for the flow you are testing and get the case set QA engineers write by hand - happy path, negative cases, boundaries, and security checks - then edit it to fit your product.

Boundary Value Analysis in One Click

For any field with a documented range or length, generate the classic boundary set: below minimum, at minimum, just above, nominal, just below maximum, at maximum, and above maximum - plus empty, wrong-type, and special-character cases.

Test Documentation That Lives With the Code

Export a Markdown table for your repo wiki, GitHub, or Notion, or CSV for Excel and Google Sheets - one line per test case with steps and expected results, ready for review.

Feature Done-Checklists

Generate the negative and security cases for a feature before calling it finished - empty fields, double submits, and injection strings are the gaps manual testing skips under time pressure.

How to Use This Tool

  1. Pick a template for the flow you are testing (or go straight to the boundary generator for one specific field)
  2. Add the template cases, then describe a field - name, type, min/max or max length - and generate its boundary cases
  3. Edit titles, steps, and expected results directly in the table; add or delete rows as needed
  4. Copy the suite as Markdown or CSV, or download it as a file
