我正在尝试使用grunt karma和karma-typecript-preprocessor自动执行单元测试。使用karma-typescript-preprocessor插件发现错误'找不到名字......'
但是，当我运行'grunt watch'时，karma输出以下错误： ERROR [preprocessor.typescript]：/home/loic/Code/appName/src/app/app.spec.ts.ktp.ts （15,13）：错误TS2304：找不到名字'expect'。
发生此错误有很多名字：“形容，角度，期望”等
奇怪的是，当我运行命令行‘TSC /path/to/app.spec.ts’，新的js文件被创建，没有错误。
下面我karma.conf.js：
module.exports = function (karma) {
karma.set({
/**
* From where to look for files, starting with the location of this file.
*/
basePath: '../',
typescriptPreprocessor: {
// options passed to the typescript compiler
options: {
sourceMap: false, // (optional) Generates corresponding .map file.
target: 'ES5', // (optional) Specify ECMAScript target version: 'ES3' (default), or 'ES5'
module: 'amd', // (optional) Specify module code generation: 'commonjs' or 'amd'
noImplicitAny: false, // (optional) Warn on expressions and declarations with an implied 'any' type.
noResolve: true, // (optional) Skip resolution and preprocessing.
removeComments: true // (optional) Do not emit comments to output.
},
// transforming the filenames
transformPath: function(path) {
return path.replace(/\.ts$/, '.js');
}
},
