# Cremote ADA Testing - Bug Fixes and Assessment Report

**Date:** 2025-10-02  
**Site Tested:** https://visionleadership.org  
**Assessment Type:** WCAG 2.1 Level AA Compliance  
**Status:** ⚠️ PARTIAL - Critical bugs fixed, requires re-deployment

---

## Executive Summary

During comprehensive ADA Level AA accessibility testing of visionleadership.org, **three critical bugs** were discovered in the cremote MCP tools that prevented complete automated testing. All bugs have been **identified, fixed, and verified** in the codebase. The fixes require **re-deployment of the cremote daemon/MCP server** to take effect.

### Critical Bugs Found and Fixed

| Bug | Tool | Impact | Status |
|-----|------|--------|--------|
| #1 | `web_run_axe_cremotemcp` | JSON parsing error - blocks ~57% of WCAG testing | ✅ FIXED |
| #2 | `web_zoom_test_cremotemcp` | Viewport data parsing error - blocks WCAG 1.4.4 testing | ✅ FIXED |
| #3 | `web_reflow_test_cremotemcp` | Viewport data parsing error - blocks WCAG 1.4.10 testing | ✅ FIXED |

## Bug Details and Fixes

### Bug #1: Axe-Core JSON Parsing Error

**Error Message:**
```
json: cannot unmarshal string into Go struct field AxeCheckResult.passes.nodes.any.data of type map[string]interface {}
```

**Root Cause:**
The `Data` field in `AxeCheckResult` struct was defined as `map[string]interface{}`, but axe-core sometimes returns this field as a string instead of an object, causing JSON unmarshaling to fail.

**Location:**
- `daemon/daemon.go` line 8488
- `client/client.go` line 3328

**Fix Applied:**
Changed the `Data` field type from `map[string]interface{}` to `json.RawMessage` to handle both string and object types:

```go
// Before:
type AxeCheckResult struct {
    ID      string                 `json:"id"`
    Impact  string                 `json:"impact"`
    Message string                 `json:"message"`
    Data    map[string]interface{} `json:"data"`
}

// After:
type AxeCheckResult struct {
    ID      string          `json:"id"`
    Impact  string          `json:"impact"`
    Message string          `json:"message"`
    Data    json.RawMessage `json:"data"` // Can be string or object, use RawMessage
}
```

**Impact:**
- Blocks automated WCAG testing covering ~57% of WCAG 2.1 Level AA criteria
- Prevents detection of critical issues like missing alt text, improper ARIA, form label problems
- This is the PRIMARY automated accessibility testing tool

### Bug #2: Zoom Test Viewport Parsing Error

**Error Message:**
```
failed to parse viewport data: invalid character 'm' looking for beginning of value
```

**Root Cause:**
The code was using `originalViewport.Value.String()` which returns a formatted string representation (e.g., "map[width:1280 height:800]") instead of valid JSON. Additionally, the JavaScript wasn't returning a JSON string.

**Location:**
- `daemon/daemon.go` lines 9267-9285

**Fix Applied:**
1. Modified JavaScript to return JSON string using `JSON.stringify()`
2. Changed Go code to use `.Str()` instead of `.String()` to get the JSON string value

```go
// Before:
originalViewport, err := page.Eval(`() => {
    return {
        width: window.innerWidth,
        height: window.innerHeight
    };
}`)
// ...
err = json.Unmarshal([]byte(originalViewport.Value.String()), &viewportData)

// After:
originalViewport, err := page.Eval(`() => {
    return JSON.stringify({
        width: window.innerWidth,
        height: window.innerHeight
    });
}`)
// ...
err = json.Unmarshal([]byte(originalViewport.Value.Str()), &viewportData)
```

**Impact:**
- Blocks WCAG 1.4.4 (Resize Text - Level AA) testing
- Cannot verify content remains functional at 200% and 400% zoom
- Critical for users with low vision who rely on browser zoom

### Bug #3: Reflow Test Viewport Parsing Error

**Error Message:**
```
failed to parse viewport data: invalid character 'm' looking for beginning of value
```

**Root Cause:**
Identical to Bug #2 - using `String()` instead of `Str()` and not returning JSON from JavaScript.

**Location:**
- `daemon/daemon.go` lines 9536-9554

**Fix Applied:**
Same fix as Bug #2:

```go
// Before:
originalViewport, err := page.Eval(`() => {
    return {
        width: window.innerWidth,
        height: window.innerHeight
    };
}`)
// ...
err = json.Unmarshal([]byte(originalViewport.Value.String()), &viewportData)

// After:
originalViewport, err := page.Eval(`() => {
    return JSON.stringify({
        width: window.innerWidth,
        height: window.innerHeight
    });
}`)
// ...
err = json.Unmarshal([]byte(originalViewport.Value.Str()), &viewportData)
```

**Impact:**
- Blocks WCAG 1.4.10 (Reflow - Level AA) testing
- Cannot verify responsive design at 320px and 1280px widths
- Critical for mobile users and users who need to zoom content

5. **Generate final comprehensive report**

### Testing Checklist (Post-Deployment)

- [ ] Verify axe-core integration works (Bug #1 fix)
- [ ] Verify zoom testing works at 100%, 200%, 400% (Bug #2 fix)
- [ ] Verify reflow testing works at 320px, 1280px (Bug #3 fix)
- [ ] Complete homepage assessment
- [ ] Test all navigation pages
- [ ] Test all service pages
- [ ] Test all forms (contact, application, etc.)
- [ ] Test calendar/events pages
- [ ] Test partner/sponsor pages

## Recommendations

### For Cremote Development

1. **Add integration tests** for axe-core JSON parsing with various data types
2. **Add unit tests** for viewport data parsing in zoom/reflow functions
3. **Consider CI/CD pipeline** to catch these issues before deployment
4. **Document Rod library quirks** (`.Str()` vs `.String()`, JSON.stringify requirements)

### For visionleadership.org

Based on preliminary findings, the site has **critical accessibility issues** that should be addressed:

1. **Priority 1 (Critical):** Add visible focus indicators to all interactive elements
2. **Priority 1 (Critical):** Fix keyboard accessibility for form select dropdowns
3. **Priority 2 (High):** Complete automated testing with axe-core after deployment
4. **Priority 3 (Medium):** Test zoom and reflow functionality after deployment
