README
Istanbul loader for webpack to instrument files for code coverage. Can be used with serverless offline to get code coverage results for integration tests.
Usage
To use the loader add it to your webpack.config.js file. You will only want to load for development / test build and not production.
Example with Typescript
const loaders = [
{
loader: '@ephesoft/webpack.istanbul.loader' // Must be first loader
},
{
loader: 'ts-loader',
options: {
transpileOnly: true
}
}
]
module.exports = {
...
module: {
rules: [
{
// Add instrumentation for test coverage on development builds
use: getMode() === 'development' ? loaders : loaders.slice(1, 2)
}
]
}
}
