AngularJS is used to create Ionic v1 applications. Jasmine and the Karma test runner are two of the many test libraries and frameworks available with Angular. Unit tests for Ionic applications may be written using these frameworks. The applications that an Ionic app development company build, can be tested in four different ways: on a desktop WebKit browser, in an iOS or Android emulator, in a mobile browser on your phone, or as a native application on your phone.
