# Test Coverage Crisis Remediation
## Issue Summary
**Severity**: 🔴 CRITICAL
**Effort**: 40-60 hours
**Priority**: P0 (Block all other work)
## Problem Description
Repository claims "100% test coverage" but analysis reveals:
- ~170 actual test assertions across entire codebase
- Majority are `assert!(true, "message")` placeholders
- No coverage tooling configured (tarpaulin, llvm-cov)
- Tests don't mount components in DOM
- No WASM test execution in CI
## Root Cause Analysis
1. **Test-Driven Development Theater**: Tests written to satisfy CI without validating functionality
2. **Missing Test Infrastructure**: No proper testing harness for Leptos components
3. **No Coverage Enforcement**: No gates preventing regression
4. **Copy-Paste Testing**: Same placeholder patterns across all components
## Remediation Steps
### Step 1: Audit Current Test Reality (4 hours)
```bash
# Count real vs placeholder tests
find packages/leptos -name "*.rs" -type f -exec grep -l "assert!(true" {} \; | wc -l
find packages/leptos -name "*.rs" -type f -exec grep -l "assert_eq!\|assert_ne!" {} \; | wc -l
# Generate coverage baseline
cargo install cargo-llvm-cov
cargo llvm-cov --html --output-dir coverage-report/
```
### Step 2: Fix Core Component Tests (20-30 hours)
Priority components to fix first:
1. **Button** - Most critical, used everywhere
2. **Input** - Form foundation
3. **Card** - Layout foundation
4. **Badge** - Simple but essential
5. **Label** - Accessibility critical
**Example Real Test (Button)**:
```rust
#[cfg(test)]
mod tests {
use super::*;
use leptos::*;
use wasm_bindgen_test::*;
wasm_bindgen_test_configure!(run_in_browser);
#[wasm_bindgen_test]
fn button_renders_with_text() {
mount_to_body(|| {
view! {
<Button>"Click me"</Button>
}
});
let button = document()
.query_selector("button")
.unwrap()
.unwrap();
assert_eq!(button.text_content().unwrap(), "Click me");
assert!(button.class_list().contains("bg-primary"));
}
#[wasm_bindgen_test]
fn button_handles_click_events() {
let clicked = create_rw_signal(false);
mount_to_body(|| {
view! {
<Button on_click=move |_| clicked.set(true)>
"Click me"
</Button>
}
});
let button = document()
.query_selector("button")
.unwrap()
.unwrap();
button.click();
assert!(clicked.get());
}
}
```
### Step 3: Add Coverage Infrastructure (8 hours)
```toml
# Add to Cargo.toml [dev-dependencies]
wasm-bindgen-test = "0.3"
web-sys = "0.3"
# Add coverage config
[toolchain]
channel = "nightly"
[env]
RUSTFLAGS = "-C instrument-coverage"
```
### Step 4: CI Integration (4-6 hours)
```yaml
# Add to CI pipeline
- name: Generate Coverage
run: |
cargo install cargo-llvm-cov
cargo llvm-cov --workspace --lcov --output-path lcov.info
- name: Upload Coverage
uses: codecov/codecov-action@v3
with:
file: lcov.info
- name: Coverage Gate
run: |
coverage=$(cargo llvm-cov --workspace --summary-only | grep "TOTAL" | awk '{print $10}' | tr -d '%')
if [ $(echo "$coverage < 80" | bc -l) -eq 1 ]; then
echo "Coverage $coverage% below 80% threshold"
exit 1
fi
```
### Step 5: WASM Test Execution (6 hours)
```yaml
- name: Install wasm-pack
run: curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
- name: Run WASM Tests
run: |
for package in packages/leptos/*/; do
cd "$package"
wasm-pack test --headless --chrome
cd -
done
```
## Success Criteria
- [ ] Real coverage report showing actual percentages
- [ ] All placeholder `assert!(true)` tests replaced
- [ ] Core 5 components have 80%+ coverage
- [ ] WASM tests running in CI
- [ ] Coverage gates preventing regression
- [ ] Documentation on how to write proper tests
## Risk Mitigation
- **Risk**: Breaking existing functionality while fixing tests
- **Mitigation**: Fix one component at a time, test in isolation
- **Risk**: WASM test setup complexity
- **Mitigation**: Use proven wasm-bindgen-test patterns
- **Risk**: Performance impact of coverage
- **Mitigation**: Only run coverage on merge requests, not every push
## Dependencies
- Rust 1.70+ for coverage tooling
- Chrome/Firefox for WASM testing
- CI runner with sufficient memory

# File Size Remediation Plan
## Issue Summary
**Severity**: 🟡 HIGH
**Effort**: 20-30 hours
**Priority**: P1 (Blocks testing and LLM comprehension)
## Problem Description
Multiple files exceed 300-line limit, impacting:
- Test granularity and isolation
- LLM context understanding
- Code review efficiency
- Maintainability and debugging
**Files Exceeding Limit**:
- `select/src/implementation_tests.rs` - 891 lines
- `button/src/tests.rs` - 844 lines
- `switch/src/implementation_tests.rs` - 760 lines
- `table/src/data_table.rs` - 689 lines
- Plus 15 more files 500+ lines
## Root Cause Analysis
1. **Monolithic Test Files**: All tests crammed into single files
2. **God Objects**: Complex components not properly decomposed
3. **Copy-Paste Inflation**: Repeated test patterns instead of helpers
4. **Missing Abstractions**: No shared test utilities
## Remediation Strategy
### Phase 1: Test File Decomposition (12-16 hours)
**Break down by test category**:
```
button/src/tests.rs (844 lines) →
├── tests/
│ ├── rendering_tests.rs (~150 lines)
│ ├── interaction_tests.rs (~150 lines)
│ ├── accessibility_tests.rs (~150 lines)
│ ├── variant_tests.rs (~150 lines)
│ ├── edge_case_tests.rs (~150 lines)
│ └── integration_tests.rs (~100 lines)
└── test_utils.rs (~50 lines)
```
**Example Decomposition**:
```rust
// button/src/tests/rendering_tests.rs
use super::super::*;
use crate::test_utils::*;
#[cfg(test)]
mod rendering {
use super::*;
#[wasm_bindgen_test]
fn renders_default_button() {
let result = render_component(|| {
view! { <Button>"Test"</Button> }
});
assert_button_has_class(&result, "bg-primary");
assert_button_text(&result, "Test");
}
// More focused rendering tests...
}
```
### Phase 2: Component Decomposition (8-12 hours)
**Break down large components**:
```
table/src/data_table.rs (689 lines) →
├── components/
│ ├── table_header.rs (~100 lines)
│ ├── table_row.rs (~100 lines)
│ ├── table_cell.rs (~80 lines)
│ ├── table_pagination.rs (~120 lines)
│ └── table_sorting.rs (~100 lines)
├── hooks/
│ ├── use_table_state.rs (~80 lines)
│ └── use_sorting.rs (~60 lines)
└── lib.rs (~60 lines - exports only)
```
### Phase 3: Shared Test Utilities (4-6 hours)
**Create common test infrastructure**:
```rust
// packages/test-utils/src/component_testing.rs
pub fn render_component<F, V>(component: F) -> ComponentTestResult
where
F: Fn() -> V + 'static,
V: IntoView,
{
// Standard component mounting and testing setup
}
pub fn assert_button_has_class(result: &ComponentTestResult, class: &str) {
// Reusable assertion logic
}
pub fn assert_accessibility_compliance(result: &ComponentTestResult) {
// Shared a11y testing
}
```
## Implementation Plan
### Week 1: Critical Test Files
**Day 1-2**: button/src/tests.rs → 6 focused test files
**Day 3-4**: select/src/implementation_tests.rs → category-based split
**Day 5**: switch/src/implementation_tests.rs → interaction focus
### Week 2: Component Architecture
**Day 1-2**: table/src/data_table.rs → component decomposition
**Day 3-4**: Remaining large implementation files
**Day 5**: Shared utilities and cleanup
### File Size Rules Going Forward
```rust
// Add to rustfmt.toml or clippy config
max_lines = 300
// Add to CI checks
- name: Check File Sizes
run: |
large_files=$(find packages/leptos -name "*.rs" -type f -exec wc -l {} + | awk '$1 > 300 {print $2 " has " $1 " lines"}')
if [ -n "$large_files" ]; then
echo "Files exceeding 300 line limit:"
echo "$large_files"
exit 1
fi
```
## Specific File Remediation
### select/implementation_tests.rs (891 lines)
**Split into**:
- `select_rendering_tests.rs` (150 lines)
- `select_option_tests.rs` (150 lines)
- `select_keyboard_tests.rs` (150 lines)
- `select_accessibility_tests.rs` (150 lines)
- `select_performance_tests.rs` (100 lines)
- `select_integration_tests.rs` (150 lines)
### button/tests.rs (844 lines)
**Split into**:
- `button_variants_tests.rs` (200 lines)
- `button_interactions_tests.rs` (200 lines)
- `button_accessibility_tests.rs` (200 lines)
- `button_edge_cases_tests.rs` (200 lines)
### table/data_table.rs (689 lines)
**Architecture refactor**:
- Extract sorting logic → `table_sorting.rs`
- Extract pagination → `table_pagination.rs`
- Extract row rendering → `table_row_renderer.rs`
- Core table logic → max 200 lines
## Success Criteria
- [ ] No files exceed 300 lines
- [ ] Test files split by logical categories
- [ ] Shared test utilities reduce duplication
- [ ] CI enforces line limits going forward
- [ ] Component architecture follows single responsibility
- [ ] Documentation updated for new structure
## Benefits
1. **Better Test Isolation**: Easier to run specific test categories
2. **Improved LLM Context**: Each file fits in model context windows
3. **Faster Code Reviews**: Reviewers can focus on specific areas
4. **Better Test Parallelization**: Categories can run independently
5. **Easier Debugging**: Smaller surface area per file
## Risk Mitigation
- **Risk**: Breaking existing imports during refactor
- **Mitigation**: Use `pub use` re-exports to maintain compatibility
- **Risk**: Test discovery issues after split
- **Mitigation**: Update Cargo.toml test configurations
- **Risk**: Increased compilation time from more files
- **Mitigation**: Profile build times, optimize if needed
## Dependencies
- Working knowledge of Rust module system
- Test infrastructure already in place
- CI pipeline for enforcement
## Owner
**Primary**: Senior Rust Engineer familiar with component architecture
**Secondary**: Test Engineer for test splitting validation
**Reviewer**: Staff Engineer for architectural approval

6. **Documentation Updates**: Align documentation with actual working state
7. **CI/CD Pipeline**: Update to reflect actual test status
### 1. Test Coverage Reality
- **Claim**: 100% test coverage, 300+ tests
- **Reality**: ~170 actual assertions, mostly `assert!(true)` placeholders
- **Impact**: No confidence in component functionality
## **Remediation Documents Structure**
### 2. Component Implementation Gaps
- **Claim**: 46 production-ready components
- **Reality**: Only ~10 have substantial implementation, many are empty stubs
- **Impact**: Components will fail in real applications
