angular - ReferenceError: describe er ikke definert Karma jasmine angular2

Jeg prøver å skrive noen tester med Jasmine og Karma i et Ionic-prosjekt V2. Jeg har lagt til pakkene, men jeg vet ikke hvorfor jeg fortsatt har problemet "describe er ikke definert". Kan noen hjelpe meg, vær så snill? Tusen takk

karma.conf.js:

 // Karma configuration
 // Generated on Thu Apr 19 2018 18:27:54 GMT+0200 (Paris, Madrid (heure 
 d’été))

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: [
],


// 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
// possible values: 'dots', 'progress'
// available reporters: https://npmjs.org/browse/keyword/karma-reporter
reporters: ['progress'],


// web server port
port: 9876,


// enable / disable colors in the output (reporters and logs)
colors: true,


// level of logging
// possible values: config.LOG_DISABLE || config.LOG_ERROR || 
config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
logLevel: config.LOG_INFO,


// enable / disable watching file and executing tests whenever any file 
 changes 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
})

}

Jeg prøvde å endre karma.config.js, men har fortsatt det samme problemet. Noen ideer, vær så snill?

Du må installere Jasmine-typinger

npm install @types/jasmine --save-dev

Du må også inkludere dem i din tsconfig.spec.json

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "outDir": "./dist/out-tsc/spec",
    "baseUrl": "./",
    "module": "commonjs",
    "types": ["jasmine", "node"],
  },
  "files": ["test.js"],
  "include": ["**/*.ts"],
  "exclude": [
    "**/e2e/*.ts",
    "**/*.e2e-spec.ts",
    "**/*.po.ts",
    "node_modules",
    "tmp"
  ]
}
