test-xcode（测试 Xcode）

Xcode Test Skill

Build, install, and test iOS apps on the simulator using XcodeBuildMCP. Captures screenshots, logs, and verifies app behavior.

Prerequisites

• Xcode installed with command-line tools
• XcodeBuildMCP MCP server connected
• Valid Xcode project or workspace
• At least one iOS Simulator available

Workflow

0. Verify XcodeBuildMCP is Available

Check that the XcodeBuildMCP MCP server is connected by calling its list_simulators tool.

MCP tool names vary by platform:

• Claude Code: mcp__xcodebuildmcp__list_simulators
• Other platforms: use the equivalent MCP tool call for the XcodeBuildMCP server's list_simulators method

If the tool is not found or errors, inform the user they need to add the XcodeBuildMCP MCP server:

XcodeBuildMCP not installed

Install via Homebrew:
  brew tap getsentry/xcodebuildmcp && brew install xcodebuildmcp

Or via npx (no global install needed):
  npx -y xcodebuildmcp@latest mcp

Then add "XcodeBuildMCP" as an MCP server in your agent configuration
and restart your agent.

Do NOT proceed until XcodeBuildMCP is confirmed working.

1. Discover Project and Scheme

Call XcodeBuildMCP's discover_projs tool to find available projects, then list_schemes with the project path to get available schemes.

If an argument was provided, use that scheme name. If "current", use the default/last-used scheme.

2. Boot Simulator

Call list_simulators to find available simulators. Boot the preferred simulator (iPhone 15 Pro recommended) using boot_simulator with the simulator's UUID.

Wait for the simulator to be ready before proceeding.

3. Build the App

Call build_ios_sim_app with the project path and scheme name.

On failure:

• Capture build errors
• Create a P1 todo for each build error
• Report to user with specific error details

On success:

• Note the built app path for installation
• Proceed to step 4

4. Install and Launch

1. Call install_app_on_simulator with the built app path and simulator UUID
2. Call launch_app_on_simulator with the bundle ID and simulator UUID
3. Call capture_sim_logs with the simulator UUID and bundle ID to start log capture

5. Test Key Screens

For each key screen in the app:

Take screenshot: Call take_screenshot with the simulator UUID and a descriptive filename (e.g., screen-home.png).

Review screenshot for:

• UI elements rendered correctly
• No error messages visible
• Expected content displayed
• Layout looks correct

Check logs for errors: Call get_sim_logs with the simulator UUID. Look for:

• Crashes
• Exceptions
• Error-level log messages
• Failed network requests

Known automation limitation — SwiftUI Text links: Simulated taps (via XcodeBuildMCP or any simulator automation tool) do not trigger gesture recognizers on SwiftUI Text views with inline AttributedString links. Taps report success but have no effect. This is a platform limitation — inline links are not exposed as separate elements in the accessibility tree. When a tap on a Text link has no visible effect, prompt the user to tap manually in the simulator. If the target URL is known, xcrun simctl openurl <device> <URL> can open it directly as a fallback.

6. Human Verification (When Required)

Pause for human input when testing touches flows that require device interaction.

Ask the user (using the platform's question tool — e.g., AskUserQuestion in Claude Code, request_user_input in Codex, ask_user in Gemini — or present numbered options and wait):

Human Verification Needed

This test requires [flow type]. Please:
1. [Action to take on simulator]
2. [What to verify]

Did it work correctly?
1. Yes - continue testing
2. No - describe the issue

7. Handle Failures

When a test fails:

1. Document the failure:

- Take screenshot of error state - Capture console logs - Note reproduction steps

1. Ask the user how to proceed: Test Failed: [screen/feature] Issue: [description] Logs: [relevant error messages] How to proceed? 1. Fix now - I'll help debug and fix 2. Create todo - Add a todo for later (using the todo-create skill) 3. Skip - Continue testing other screens
2. If "Fix now": investigate, propose a fix, rebuild and retest
3. If "Create todo": load the todo-create skill and create a todo with priority p1 and description xcode-{description}, continue
4. If "Skip": log as skipped, continue

8. Test Summary

After all tests complete, present a summary:

## Xcode Test Results

**Project:** [project name]
**Scheme:** [scheme name]
**Simulator:** [simulator name]

### Build: Success / Failed

### Screens Tested: [count]

| Screen | Status | Notes |
|--------|--------|-------|
| Launch | Pass | |
| Home | Pass | |
| Settings | Fail | Crash on tap |
| Profile | Skip | Requires login |

### Console Errors: [count]
- [List any errors found]

### Human Verifications: [count]
- Sign in with Apple: Confirmed
- Push notifications: Confirmed

### Failures: [count]
- Settings screen - crash on navigation

### Created Todos: [count]
- `006-pending-p1-xcode-settings-crash.md`

### Result: [PASS / FAIL / PARTIAL]

9. Cleanup

After testing:

1. Call stop_log_capture with the simulator UUID
2. Optionally call shutdown_simulator with the simulator UUID

Quick Usage Examples

# Test with default scheme
/test-xcode

# Test specific scheme
/test-xcode MyApp-Debug

# Test after making changes
/test-xcode current

Integration with ce:review

When reviewing PRs that touch iOS code, the ce:review workflow can spawn an agent to run this skill, build on the simulator, test key screens, and check for crashes.
