qckfx vs XCUITest
Overview
XCUITest
XCUITest is Apple's native UI testing framework built on XCTest. Tests are written in Swift or Objective-C and rely on explicit assertions.
qckfx
qckfx records real simulator usage and replays it deterministically to show exactly what changed between runs.
Key Differences
Test Creation
XCUITest
Developers write UI test code and assertions.
qckfx
Humans or agents drive the simulator; flows are recorded automatically.
Verification Model
XCUITest
Pass/fail based on predefined assertions.
qckfx
Replays full flows and shows visual, log, and behavioral diffs.
Change Visibility
XCUITest
Only validates what is asserted.
qckfx
Provides blanket coverage of recorded behavior and highlights any deviation.
Agent Workflow
XCUITest
Agents must generate and maintain test code.
qckfx
Agents can drive the simulator via CLI or MCP and record new replay baselines without writing tests.
When XCUITest Is a Better Fit
- —You want fine-grained assertion control.
- —You are deeply integrated with XCTest tooling.
- —You prefer fully code-defined contracts.
When qckfx Is a Better Fit
- —You want to see everything that changed in a PR.
- —You want regression coverage without writing tests.
- —You want flows recorded by humans or agents.
