Get code coverage on an angular clean install
- Create a new angular app using angular cli
ng new cypress-angular-coverage-example
- Install cypress-schematic to switch from protractor to cypress e2e framework
ng add @briebug/cypress-schematic
- Install ngx-build-plus to extends the Angular CLI's build process and instrument the code
npm i -D ngx-build-plus
- Add webpack coverage config file coverage.webpack.js to cypress folder
module.exports = {
module: {
rules: [
{
test: /\.(js|ts)$/,
loader: 'istanbul-instrumenter-loader',
options: { esModules: true },
enforce: 'post',
include: require('path').join(__dirname, '..', 'src'),
exclude: [
/\.(e2e|spec)\.ts$/,
/node_modules/,
/(ngfactory|ngstyle)\.js/
]
}
]
}
};
- Update angular.json to use ngx-build with extra config
"serve": {
"builder": "ngx-build-plus:dev-server",
"options": {
"browserTarget": "cypress-angular-coverage-example:build",
"extraWebpackConfig": "./cypress/coverage.webpack.js"
},
- Instrument JS files with istanbul-lib-instrument for subsequent code coverage reporting
npm i -D istanbul-instrumenter-loader
- Add cypress code coverage plugin
npm install -D @cypress/code-coverage
- Then add the code below to your supportFile and pluginsFile
// cypress/support/index.js
import '@cypress/code-coverage/support'
// cypress/plugins/index.js
module.exports = (on, config) => {
require('@cypress/code-coverage/task')(on, config);
return config;
};
