Test Case Generator

Define conditions and expected outcomes — generate numbered, executable test cases (TC-001…) from all 2^N combinations, with impossible-row exclusion and Markdown/CSV export.

Conditions (boolean — each is Y or N in the test matrix)

Expected outcome (when all conditions are met)

The outcome field is shared across all rows — add per-row notes after generating.

HOW TO USE

  1. 01Add each condition and its states (e.g. Valid email = Yes/No).
  2. 02The tool enumerates every combination as TC-001, TC-002…; mark impossible combinations to exclude them.
  3. 03Add notes to any case, then Copy the table or Download CSV for hand-off to execution.

Try it

Conditions: Valid email (Y/N), Correct password (Y/N), Account active (Y/N) → 8 TCs

WHEN TO USE

Use when you need to turn a set of conditions (field states, system states, user roles) into a complete, numbered, executable test suite. The generator enumerates every valid combination as TC-001, TC-002 … so nothing is missed. Mark impossible or inapplicable combinations to exclude them from the output. Ideal after you've designed the logic with a decision table and need runnable test cases for hand-off to execution.

WHAT BUGS THIS FINDS

  • Untested condition combinations

    Manually designed test suites miss combinations — the generator proves no combination has been skipped.

  • Undocumented impossible states

    Marking impossible rows forces the team to document WHY a combination cannot occur — uncovers invalid assumptions.

  • Missing negative paths

    Every N condition in the generated table is a negative test case that is easy to skip in manual design.

QA USE CASES

01

Login combinations

Conditions: email valid/invalid, password correct/incorrect, MFA on/off → 8 test cases covering every state

02

Checkout eligibility

Conditions: cart non-empty, address valid, payment method set → 8 TCs, mark 'empty cart + proceed' as impossible

03

API permission matrix

Conditions: auth token present, role=admin, resource owner → TC table drives permission-boundary tests

04

Form submit edge cases

Conditions: required fields, file attached, terms accepted → numbered TCs map to test rail entries
