What testRigor does well

•Natural-language test authoring that avoids selectors and describes behavior from the end user's perspective
•Cross-platform coverage: web, mobile, API, and desktop from a single tool
•Gartner Cool Vendor recognition and Inc. 5000 growth - $15M revenue, growing fast
•15x faster test creation claimed vs. coded frameworks, with 95% less maintenance

Where testRigor falls short

—Every test is manually authored - testRigor doesn't generate tests from code changes. You write every test, and when your UI changes, you maintain every test
—No built-in test management - users report resorting to spreadsheets to organize and track tests
—CI/CD integration requires copy-pasting bash scripts into your pipeline, rather than installing a GitHub App with PR comments
—Pricing scales with parallel execution servers, not usage - $900/month at 2 parallel servers, with limited support below enterprise tier
—No structured run evidence - no JSON run evidence with recordings and step traces

How Zerocheck differs

Coverage suggestions from app discovery and PR diffs, so teams spend less time deciding what to test from scratch
GitHub App PR gating with comments, screenshots, step traces, and evidence. No bash scripts to maintain
JSON run evidence generated from executed browser runs - record screenshots, recordings, and step traces
Semantic resolution with confidence checks - low-confidence actions fail with evidence instead of silently passing

FAQ

How is Zerocheck different from testRigor?

Both use natural-language test authoring. testRigor requires you to manually write every test using a documented syntax. Zerocheck generates tests from app discovery and PR diffs for review, then runs approved generated and human-authored tests in the GitHub PR workflow. testRigor also lacks native GitHub integration and run evidence generation.

How much does testRigor cost?

testRigor pricing starts free for limited use and goes to $900/month at 2 parallel execution servers. Support below enterprise plans is limited. Zerocheck uses flat pricing with full support included.

Does testRigor integrate with GitHub PRs?

testRigor CI/CD integration requires copy-pasting bash scripts into your pipeline. Zerocheck installs as a GitHub App and provides pass/fail comments, step traces, and evidence directly in every pull request.

Can testRigor generate tests automatically?

No. testRigor requires you to manually author every test, although in natural language rather than code. Zerocheck discovers risky flows and saves suggested tests from app discovery and PR diffs for review before they become active coverage.
