Chapter 5: Experimentation and Testing 5.1. Test Cases To test the functionalities of the system, test cases are developed. System may contain bugs, errors or unhandled exceptions which must be handled before the delivery to the owner. Companies specially hire software testers. Test cases output decides whether the system is performing good under the specific conditions or not. 5.2 Unit / Integration / Acceptance Testing: In the process of unit testing we test each of our component separately. The two main components of our Applications are User APK and manage APK. User APK is free for users end to control the current pandemic this would be a small contribution from our side to the society/world in return. While Manage APK will cost a small setup amount in order to manage their inventory over the application. In the process of integration testing we test each of our individual component in combination. In this level of testing we check that based on the data stored in our firebase database. We check whether the techniques are working properly or not. In the process of integration testing we test each of our system is compliance with the functional or non-functional requirement and check the whole system performance . 5.2.1 Black box Testing Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied to virtually every level of software testing: unit, integration, system and acceptance. Specific knowledge of the application's code/internal structure and programming knowledge in general is not required. The tester is aware of what the software is supposed to do but is not

aware of how it does it. For instance, the tester is aware that a particular input returns a certain, invariable output but is not aware of how the software produces the output in the first place.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
