API test data
Keep the remaining fields valid so a failed request can be traced to the rule under test.

User guides
These QA tools are free to use without an account. Choose a tool to see how to enter data and use the results.
Pairwise testing
Compare all combinations with Pairwise, then apply exclusions to build your test set.
JSON comparison
If timestamps or array order create noise, set comparison rules that match your test objective first.
Test data generation
Generate synthetic emails, UUIDs, strings, numbers and dates. Learn how to configure each type and copy values without JSON keys.
Test-case drafts
Prepare test-case drafts from requirements. Learn how document extraction, OCR, source review and spreadsheet exports fit into a review workflow.
Boundary value analysis
Use boundary value analysis to check values inside and outside a numeric range. Work through an integer age range of 18–65.
What you can do
- Build positive, negative and boundary request data.
- Reduce combinations with Pairwise and explicit exclusions.
- Compare JSON and validate supported structure rules.
- Draft test cases from Korean requirements and review them before export.
- Generate diagnostic scripts to run on your own computer.
