你如何设置业力测试运行器来生成打字稿项目的代码覆盖率报告?
鉴于以下文件夹结构和 karma.conf.js 文件,我已经在使用 karma 来运行我用 TypeScript 编写的测试。
我已经摆弄了karma-coverage
,remap-istanbul
但还没有任何运气。如果可能的话,我想在没有任何额外npm scripts
的 .

业力.conf.js
var istanbul = require('browserify-istanbul');
module.exports = function(config) {
config.set({
basePath: '',
frameworks: ['mocha', 'chai', 'sinon', 'browserify'],
files: [
'test/**/*Spec.ts'
],
exclude: [
],
preprocessors: {
'test/**/*Spec.ts': ['browserify']
},
browserify: {
debug: true,
plugin: ['tsify'],
transform: [
istanbul({irgnore: ['**/node_modules/**']})
]
},
reporters: ['progress', 'coverage']
})
}
更新1:
我通过添加browserify-istanbul
到设置取得了一些进展。我认为整体指标很好,但源文件视图有点奇怪。
addSpec.ts
import { add } from '../src/add'
const expect = chai.expect
describe('test add module', () => {
it('should add 2 numbers', () => {
expect(add(2, 2)).to.be.equal(4)
})
})
更新 2:
直到今天,我还想不出一种方法来使用 browserify 和 typescript 创建一个“集成的”业力设置。不过,我有一个不同的解决方案对我有用。
