Problem with Jasmine in Angular 5 within Visual Studio Code

I am completely new to Angular 5 Unit testing and facing some challenges. Despite installing all @types/jasmine, I am encountering errors in my spec.ts file such as 'describle is not a name' and 'jasmine.createSpyObj does not exist on the typeof Jasmine'. It is worth mentioning that I have imported jasmine in my spec file using import {} from 'jasmine', but it doesn't seem to be helpful.

package.json

"devDependencies": {
    "@angular/cli": "1.6.5",
    "@angular/compiler-cli": "^5.0.0",
    "@angular/language-service": "^5.0.0",
    "@types/jasmine": "^2.8.8",
    "@types/jasminewd2": "~2.0.2",
    "@types/node": "~6.0.60",
    "codelyzer": "^4.0.1",
    "jasmine-core": "^2.99.1",
    "jasmine-spec-reporter": "~4.1.0",
    "karma": "~1.7.0",
    "karma-chrome-launcher": "~2.1.1",
    "karma-cli": "~1.0.1",
    "karma-coverage-istanbul-reporter": "^1.2.1",
    "karma-jasmine": "~1.1.0",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~5.1.2",
    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "~2.4.2"
}

tsconfig.json

"compileOnSave": false,
"compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
        "node_modules/@types"
    ],
    "lib": [
        "es2017",
        "dom"
    ]
}

I have exhausted all possible solutions but still can't figure out why I am having issues in my Spec.ts file. Even the intellisense feature in VS code is malfunctioning, showing me numerous semantic errors.

Answer №1

Here's a helpful hint based on my own experience:

I encountered a similar issue when I tried to open a folder containing multiple projects. However, once I opened a single project with the tsconfig.json file located in the root folder, the problem disappeared.

This solution may work for you as well.

Answer №2

import('karma-mocha'),
import('karma-mochawesome-reporter'),
import('karma-coverage-istanbul'),
import('karma-htmlfile-reporter'),
import('karma-junit-reporter'),
import('@angular/cli/plugins/karma'),

Consider including these plugins in your karma.conf.js file for improved test reporting and coverage.
