Error: The function 'describe' has not been defined in the Karma jasmine angular2 environment

Struggling with writing tests using Jasmine and Karma in my Ionic project V2. All necessary packages have been added, but I'm still encountering the issue "describe is not defined". Can anyone offer assistance? Thank you.

Here's my 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
})

}

Despite altering my karma.config.js file, the issue persists. Any suggestions, please?

If you want to utilize jasmine typings in your project, you will need to follow these steps:

npm install @types/jasmine --save-dev

Furthermore, ensure that you include them in your 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"
  ]
}
