Difficulties and Risk for User Interface design in Android

Android Training in Chandigarh : Difficulties and Risk for User Interface Design In Android

let us take a scenario on the risk and difficulties for user interface in Android with Android Training in Chandigarh. These are as follows :

1. User Differ Widely :

i.  Account for differences among users when anyone design the system.

ii. Design is for internationalization.

iii. In User Differ widely when usability is performed from anyone at that time try the system with many different types of users.

2. User Interface Implementation Technology Changes Rapidly :

i. Stick to simpler UI (User Interface)  Framework widely used by others.

ii. Avoid Fancy and unusual UI (User Interface) designs involving specialized  controls that will be hard to change.

3. User Interface Design and Implementation can often take the Majority of work in an Application :

i. Make UI (User Interface) design an integral part of the software engineering process.

ii. Allocate time for many iterations of prototyping and evaluation.

4. Developers Often Underestimate the weaknesses of a GUI :

i.  Make it  Ensure that all software Engineers have training in UI (User Interface ) development.

ii. Always test with users

iii. Study the User Interface of other software's.

System Testing and Maintenance :

1. Testing :

Testing is the criteria with the intent of finding errors to execute a program. Testing is a program consists of subjecting the program to a set of test inputs (or test cases) and observing if the program behaves as test inputs(or test cases) and observing if the program behaves as expected.

Different level of testing are used,which performs different tasks and aim to test different aspects of the system. These different levels of testing attempt to detect different types of faults. The relation of the faults introduced at different phases, and the different levels of testing.

The different levels of testing are :

1. Unit Testing : Unit testing is undertaken when a module has been coded and successfully reviewed. Unit testing effort is mainly on the smallest unit of software unit. It is Software component and module.

2. Integration Testing : Integration testing is a systematic technique for constructing the program structure while at the same time conducting tests to uncover errors associated with interfacing , ,Integration Testing - The main objective is to take unit tested components and build a program structure that has been dictated by design.

3. Validating testing : After Integration testing, system is assembled as a package where interfacing errors have been uncovered and corrected ,and then validation testing may begin.

4. System Testing: System Testing is a series of different tests whose primary purpose is to fully exercise the computer-based system. Each Test has a different purpose for the various system elements that have been properly integrated.
