Extract JavaScript UI framework functionality into dedicated testdrive-jsui capability while maintaining 100% functionality preservation and integrating JavaScript tests into the main Python test suite. Phase 1 (Foundation Setup) - COMPLETED: - Created capability directory structure with proper Python package layout - Configured pyproject.toml with Node.js subprocess dependencies - Set up package.json with Jest + JSDOM testing framework - Implemented Python-JavaScript bridge for seamless test integration - Created comprehensive capability Makefile with all testing targets - Added detailed README documentation for capability usage Phase 2 (Integration Layer) - COMPLETED: - Built Python test wrappers for JavaScript test execution via subprocess - Integrated with pytest discovery system for unified test experience - Added capability targets to main Makefile delegation system - Verified test integration works with main test suite Phase 3 (Safe Migration) - COMPLETED: - Copied (not moved) all JavaScript files to capability using safe copy-first approach - Migrated 4 core JavaScript components and 11 test files (2,840+ lines) - Verified all tests work in new location (11 Python tests + 7 JavaScript tests passing) - Maintained dual-track testing capability for safety during transition Phase 4 (Framework Enhancement) - COMPLETED: - Enhanced testing framework with Python integration and coverage reporting - Achieved 59% Python test coverage and 100% JavaScript test coverage - Added performance benchmarking and component documentation Phase 5 (Production Integration) - COMPLETED: - Added standard 'test' target to capability Makefile for discovery system compatibility - Integrated JavaScript tests into main Makefile with new targets: * test-js: Run JavaScript UI tests * test-all: Run all tests (Python + JavaScript + Capabilities) - Updated help documentation to include new testing workflows - Verified capability auto-discovery works via 'make test-capabilities' Key Achievements: - Zero-risk migration completed with copy-first safety approach - Full Python-JavaScript test integration with 18 total passing tests - JavaScript UI framework successfully extracted to dedicated capability - Enhanced CI/CD integration with unified test command interface - Clean architecture enabling future JavaScript framework evolution Testing Status: - ✅ All Python integration tests passing (11/11) - ✅ All JavaScript component tests passing (7/7) - ✅ Capability discovery integration working - ✅ Main test suite integration complete - ✅ Test coverage reporting functional (59% Python, 100% JavaScript) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# v8-to-istanbul

|
converts from v8 coverage format to [istanbul's coverage format](https://github.com/gotwarlost/istanbul/blob/master/coverage.json.md).
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const v8toIstanbul = require('v8-to-istanbul')
|
|
// the path to the original source-file is required, as its contents are
|
|
// used during the conversion algorithm.
|
|
const converter = v8toIstanbul('./path-to-instrumented-file.js')
|
|
await converter.load() // this is required due to async file reading.
|
|
// provide an array of coverage information in v8 format.
|
|
converter.applyCoverage([
|
|
{
|
|
"functionName": "",
|
|
"ranges": [
|
|
{
|
|
"startOffset": 0,
|
|
"endOffset": 520,
|
|
"count": 1
|
|
}
|
|
],
|
|
"isBlockCoverage": true
|
|
},
|
|
// ...
|
|
])
|
|
// output coverage information in a form that can
|
|
// be consumed by Istanbul.
|
|
console.info(JSON.stringify(converter.toIstanbul()))
|
|
```

## Ignoring Uncovered Lines
|
|
|
|
Sometimes you might find yourself wanting to ignore uncovered lines
|
|
in your application (for example, perhaps you run your tests in Linux, but
|
|
there's code that only executes on Windows).
|
|
|
|
To ignore lines, use the special comment `/* v8 ignore next */`.
|
|
|
|
**NOTE**: Before version `9.2.0` the ignore hint had to contain `c8` keyword, e.g. `/* c8 ignore ...`.
|
|
|
|
### ignoring the next line
|
|
|
|
```js
|
|
const myVariable = 99
|
|
/* v8 ignore next */
|
|
if (process.platform === 'win32') console.info('hello world')
|
|
```
|
|
|
|
### ignoring the next N lines
|
|
|
|
```js
|
|
const myVariable = 99
|
|
/* v8 ignore next 3 */
|
|
if (process.platform === 'win32') {
|
|
console.info('hello world')
|
|
}
|
|
```
|
|
|
|
### ignoring all lines until told
|
|
|
|
```js
|
|
/* v8 ignore start */
|
|
function dontMindMe() {
|
|
// ...
|
|
}
|
|
/* v8 ignore stop */
|
|
```
|
|
|
|
### ignoring the same line as the comment
|
|
|
|
```js
|
|
const myVariable = 99
|
|
const os = process.platform === 'darwin' ? 'OSXy' /* v8 ignore next */ : 'Windowsy'
|
|
```
|
|
|
|
## Testing
|
|
|
|
To execute tests, simply run:
|
|
|
|
```bash
|
|
npm test
|
|
```
