angular cli 6, ng test not working

Question

I have just updated my angular project to angular 6.

ng build and ng serve work, but when I run my tests with the command:

ng test 

I get the output:

Schema validation failed with the following errors: Data path "" should have required property 'tsConfig'. 

tsconfig.json:

{ "compilerOptions": { "baseUrl": "", "declaration": false, "emitDecoratorMetadata": true, "experimentalDecorators": true, "lib": [   "es2016",   "dom" ], "mapRoot": "./", "module": "es2015", "moduleResolution": "node", "outDir": "../dist/out-tsc", "sourceMap": true, "target": "es5", "typeRoots": [   "../node_modules/@types" ] } } 

What am I doing wrong ?

Answer 1

I solved it. Somehow when I upgraded the project to Angular 6 the tsConfig key was missing under test -> options in angular.json.
