Hi Sanjit, This file is used for the setting of a testing environment with the help of karma and jasmine. We are using it for unit testing using test bed. I will explain the detail about it in my later article. Hope Its help you. Thanks

Hi Manav, Thank You so much for the reply but I know the component.spec.ts and test.ts is diffrent and This file is required by karma.conf.js and loads recursively all the .spec and framework files.
