Grunt task for jscoverage; which will parse your source code and generate an instrumented version allowing testing tools to generate code coverage reports.
Install npm package
npm install grunt-jscoverage --save-dev
Add this line to your project's Gruntfile:
grunt.loadNpmTasks("grunt-jscoverage");
grunt.initConfig({
jscoverage: {
src: {
expand: true,
cwd: 'src/',
src: ['**/*.js'],
dest: 'src-cov/',
ext: '.js',
},
otherstuff: {
expand: true,
cwd: 'otherstuff/',
src: ['**/*.js'],
dest: 'otherstuff-cov/',
ext: '.js',
},
options: {
// custom options
}
}
});See Grunt docs for detailed explanation.
Options will be passed to jscoverage as is. Unfortunately, jscoverage doesn't provide any documentation about its programmatic API, so take a look at function processFile() in its file index.js for details.
