Angular cli showing error "An unhandled exception occurred: No projects support the 'test' target." when running ng test or ng serve command

I have a basic angular application , which was working fine. The ng serve and ng test commands were working fine. Recently as part of build automation for different environments , I introduced some configuration changes to allow different environment.ts files to be loaded as per environment . For that I edited the angular.json file.After the changes , the ng serve and ng test command fails to execute. Whenever the commands are executed the following error is thrown :

An unhandled exception occurred: No projects support the 'test' target.
See "C:\Users\account\AppData\Local\Temp\ng-BlbvgV\angular-errors.log" for further details.

The modified angular.json is :

I found the issue, it was a mis-placed } . I closed the "build" goal before configuration , which was causing the issue.Corrected angular.json :
