 To implement the build and test system
It make simple and efficient for client to get in touch with the organization and offer them
different tools to make their life become easier by using mobile application. Main objective is to
keep track the testing and also build or test system that send email to ever. Build and test system
is a automated software that allows development of automated software that helps in
automatically compiling and computer source code into binary code and testing the software

automatically. Best build automation tool for the company includes Codeship, Gradle, Jenkins
etc.
Purpose – The purpose of project is to enhance and build understanding from the
requirement of mobile application development. It is easily gathering all the activities in the
applications. The main purpose of these tools is to develop a software where build automation
tool are the part of software development lifecycle which allows the compiling of source code
into machine code.

anbd other affinity diagram tool from the Android smart phone. Mobile application is small part
of large set of operations that can be added for one time. The overall application will allow for
user to use th Xamarin tool and develop the applications. The company is planning to develop
new software that helps in building the automated software and testing tool that encourage

mailing system to describe the current status of the software testing. Along with this Coideship
tool is used to convert the sour ce code into binar y code.
Product features-
Xamarin tool is the best that support the android operating system that easily install to
run the programs in proper manner. It helps for user to collaborate simultaneously as if they were
doing on the computer system by using web browsers (Falessi and et.al., 2018). This tool can be
reused for the prupose of business logic and easily access the data at any platform. It is widely
applicable in the mobile application of android platform. It enables to communicate with the
application in mobile devices.
Operating environment-
The Mobile applican will run on the android platform where all the devices are supports.
Application can be developed with the helpf Xamarin. It also utilized the overall functionality of
tool which applicable in system at same level. Mobile application is generally used the same
functionality as web tools and should be persisted the information in the same type of database.
This software will help organisat ion in developing a aut omated mobile tracking application that
provides timely not i fication regarding the marketing updates and software updates. This
software also control the automated tasks of the company.

Verify and validate the requirements
Mobile application testing is the important part of testing analyst to viusulize all the
requirement and also must be tested the functionalty of application. The mobile devices are

extremely fragmented becuase there are various type of devices, screen resolution and operating
system applications (Mall, 2018). All make testing a mobile application in cost and time
effective. Functional testing is a critical steps on mobile application that help to meet the
requirement of business.
User interface testing-
This type of testing is verifying the mobile application that return the correct UI ouput
according to the input. It is a sequence of user action on devices such as images, UI control,
press tool bars and other dialogs etc. It includes Graphic display, colour palette and UI
consistency etc.
Integration testing-
This testing is basically focused on the internal mechanism of applications as well as their
integration of application with external app such as twitter, sales force and share point etc. This
type of testing is started at lower level components and continuously tested the overall
hierarchical component of application. It is an efficient testing that support to find the errors and
easily detect in the external or internal integration of mobile application.
System testing-
All the components are integrated with the testing procedures and sucessfully completed
in proper manner. The over all testing occurs to meet the high quality of standards. This testing
process is verify and validate the mobile application for the purpose of business requirement as
well the architecture of application.
Regressive testing-
Whenever the change happen in the mobile application, it is quite possible that
application affected by this changes. This type of testing is to ensure that the change occurs such
as fixing the bugs and cannot be recognized the faulty errors in the application. It helps for
minimizing the gap in the testing when changes are made in the application.
User Acceptance testing-
The mobile application is tested by the uer acceptability to validate the end to end
business information flow in the mobile application. This type of testing is executed by UAT
users in the production

Reviewing the requirement specifications Activity
A technical specification is basically type of documents that define as a set of
requirement in mobile application. It can be used when the contract for technical product and
services.
User interfaces-
The user interfaces show the proper notification for meeting and it is personally designed
the mobile application. It allows the user to continually customize their accurate schedule time.
User easily access the information about the product and their features which already available
on the mobile application.
Hardware interface-
The mobile application is designed for people those who are already use the android
smartphones. It can easily access the information about the organization as well as products.
Communication Interface-
Mobile application will suitable and utilise in the hardware networking whereas users
access the information through smartphones. Network communication services is also provided
by the android operating system. It has more capability to connect with the remote database as
well as authentication web server.
Software interface-
The mobile application will run the android platform that exist in the smartphones
devices. The size is around 11mb. It is responded to the size of windows and screen of phone
where application is running.
Security-
Security is a main component of mobile application that is needed for developer to use
the different protocol to secure the data because there are many attacker damage the entire
functionality of business process ( Mendes and et.al., 2018). It is directly impact on the personal
information of customers.
These are different type osf specification required during the mobile application
development because it can easy for the developer to add features on mobile application. There
are different ways to create technial specification about the mobile applications.

The mobile application will maintain a list of classes for the users
Description: Mobile application will store the information regarding the organization
whereas user can easily access the data through application. It should be editable, accessible and
persistent among the lifetime of application. It can be used the different attributes that describe
the classed of subsequent needs.
Technical issue- The application must be used the input that provided but the user and
other external web services to create a list of classes that easily associated with the users. This
type of application would able to store the data in such manner and if the application is
terminated and started.
Risks – It is less risk and implementing the technical aspects which relatively
straightforward and they have no dependency in the network as well as database connection.
The application should be notified that the user when their login page is closed to specific
date.
Description – if the application is provided the notification to the user when their login
time should out if the user has specified option to again login their profile.
Critically – Less
Technical issues – user can give input so that application can be generated an output. It
also providing the notification related the due date.
Risk – If the frame work of application doesn't provide the proper mechanism of triggers
UI notification, in this way, the requirement cannot be fulfilled in proper manner.
Sometimes, the implementation of feature is very complex and it may not properly
completed their development time allocated for mobile application.
The user shall be able to set the information about the particular products belongs to
Description – When it creates a product information or editing the details. User should
able to specify which products from the list of classes of the latest features associated with items
Critically- Medium
Technical issues- input: existing and new product lists, users are directly interact with
the list of items, output : it is generated a set of association among the product and list or classes.
Risks- There is minimum risk in the process and it also added simple implementation.
They have limited complex dependencies.

Prototype the requirements:
The application development life cycle is a procedure that help for remove the errors,
bugs in the system. It can be used the prototype which help for prevention of fatal blunders in the
designing, planning and development of application. It always encourages the communication,
reduce the errors and risk in proper manner. It is used the Marvel prototype in the mobile
application because this tool is basically used for designing such as sketch or photo-shop etc. it
easier for developer to store in the cloud storage such as Google Drive and Dropbox etc.
Marvel prototype tool is providing the interactive Fidelity in the mobile application
because it always maintains the flow of communications (Niua and et.al., 2018). This tool is an
attractive idea for project development. It also supports the different type of variables and their
managing states m reuse the elements and detailed event etc.
Developer is follows the process for building a mobile application by using prototype
tool with smart goals and objectives. It is a good step to meet the project requirement for the
prototype (Venters and et.al., 2018). There are major implications for software compatibility,
workflow and testing process. Marvel prototype should have easy features whereas developer
can apply the concept no matter how it is complex. In this way, A strong UI library component
support the variety of interaction pattern.
Developer can use the Marvel prototyping tool that should add some features on the
mobile applications such as
 To provide the custom component library that support to specify for the mobiles
 Output demo to the mobile to preview the effect easily.
 This tool can be supported the mobile gesture operations.
 It also supports the transition animation in the different switches of mobiles views. It is quickly generated a complete work flow.
Specific Requirement-
 Operating system – windows XP, Window 7
 Processor- intel core Duo 2.6GHz,
 Duo - 2.6GHz,
 Video Card - NVIDIA GeForce 8800 GT
 Sound - DirectX 9.0 Compatible Sound Card

 Memory- 2 GB RAM.
Discussion- 7
Reuse the requirements
A mobile application component is basically reused the library that developer can add the
specific application. It happens on the client side library. Developer will create reusable library
that help for controlling the entire mechanism. In this way, The Basic information related the
component is displayed on screen.
From the developer or programmer is trying to reuse the component that already exist in
another applications. In this way, it will help for final development to reduce the time with the
product cost. In this way, stakeholders are satisfied related the project (Vegendla and et.al.,
2018). Code re-usability is the best method that can use the similar code functionality without
rewriting it.
The functionality of code re-usability can follow some specific parameter to analyse the
specific criteria in the web interface. In mobile application, it can be used the internal and
external code among the set of projects. It is required primary tables such as “android class,”
“android package”,” android projects”, “android components”.
CONCLUSION
As per discussion, it concluded that Mobile application is beneficial for organization to
track the details of consumers. The need and requirement of mobile application that help for
organization to easily track or manage the testing continuously in project development. In mobile
application, developer can implement a new prototype that help for managing and controlling the
inputs and outputs. It discusses about the objective and scope of project. It verifies and validates
the requirement for project development. It also reviews the requirement of specification and
prototype.
RECOMMENDATION
It has recommended that the designer used the Marvel prototype tool which providing
the interactive Fidelity in the mobile application because it always maintains the flow of
communications. Many mobile phones have already exists the software and hardware
constraints. Database has used for the application to store all the information that can use by

using Xamarin tool. The application must use the Java plus ad Android SDK that support by
android development environment.
