angularjs - 如何使用 Angular 2 CLI 设置 Istanbul 尔代码覆盖率？

Question

我不确定我是否了解 Istanbul 尔的设置。

所有教程只测试一个或两个文件。您如何设置它以便测试您的整个代码库？我理解错了吗？

我可以向您展示我的 karma.conf，它目前显示代码覆盖率(尽管我还没有让它与 Typescript 一起使用):

config.set({ 
    basePath: "./", 
    frameworks: ["jasmine"], 
    files: [            
        //load files here, including your spec and source files
    ],
    // Other settings...
    browsers: ["PhantomJS"],
    plugins: [
        "karma-jasmine",
        "karma-coverage", //<-- using karma-coverage for code coverage
        "karma-chrome-launcher",
        "karma-phantomjs-launcher"
    ],
    // Coverage reporter generates the coverage
    reporters: ["progress", "coverage"], //<-- reporter for code coverage
    // Source files that you wanna generate coverage for.
    // Do not include tests or libraries (these files will be instrumented by Istanbul)
    preprocessors: {
        "test/bin/js/app/**/!(*spec).js": ["coverage"] //<-- coverage pre-process
    }, 
    // Generate the code coverage report (lots of formats available)
    coverageReporter: {
        reporters:[
            { type: "html", dir: "./test/bin", subdir: "coverage/html" }
        ]
    },
    singleRun: true
})

在您的 package.json 中，包括“业力覆盖”:“1.1.1”作为开发依赖

希望这至少能为您指明正确的方向。
