typescript - Typescript、Babel 7、Karma、Jasmine、代码覆盖率配置
问题描述
我正在使用 Typescript 开发一个独立的库,并尝试使用 Karma、Jasmine 和 Babel 7 设置单元测试和代码覆盖率。我编写了几个简单的测试并试图让 Karma 运行它们,但零测试正在运行。消息03 08 2019 07:36:35.252:WARN [middleware:karma]: Invalid file type (ts), defaulting to js.
在控制台发出,然后是Executed 0 of 0 ERROR (0.005 secs / 0 secs)
. 这告诉我我在 Karma 配置文件中遗漏了一些东西,但我不确定丢失的部分是什么。
业力.config.js
module.exports = function (config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine'],
// list of files / patterns to load in the browser
files: [
'src/**/*.ts'
],
// list of files / patterns to exclude
exclude: [],
// preprocess matching files before serving them to the browser
// available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
preprocessors: {

},
// test results reporter to use

}
]
},
// web server port

colors: true,

autoWatch: true,
// start these browsers
// available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
browsers: ['Chrome'],
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: false,
// Concurrency level
// how many browser should be started simultaneous
concurrency: Infinity,
});
