Fall 2018 Senior Design Project

Police officers have a manual

system to create and distribute

information pertaining to a crime. The

information can take from 24 to 48

hours to be spread throughout a

single police department. Therefore,

the time and probability to apprehend

a criminal become inversely

proportional. Incrementing the time

and decreasing probabilities to solve a

crime.

There is a system in place that has

been developed by FIU engineers.

The system meets all functional requirements,

but does not meet with new non-functional

requirements set by stakeholders. The

decision was made to restructure the entire

application.

My contributions to this new version for BOLO

are:

• Generated major views for the application

• Managed Create BOLO

• Managed List of BOLOs

The system shall:

User Interface

Unit and integration testing were implemented by using

Jasmine Behavior-Driven JavaScript and Karma. Also

System testing was implemented with various

sequences of Sunny Day and Rainy Day Test Cases

Scenarios. The objective of our System Tests was to

make sure that the system was behaving appropriately,

as defined by the requirements provided by our product

owners.

The goal of the project is to build a BOLO Flyer Creator

web application that will speed the process of creating a

BOLO (Be On the Lookout). The BOLO app is being

restructured in order to suffice new requirements from

stakeholders. This first iteration of the product

implemented major views of the application and more

than 70 % of functionalities like: Login View, Bolo

Creation, Email Confirmation, Bolo View Details, List of

Bolos View, Pagination for list of BOLOs view among

others.

System Design

In order to create a BOLO, the user

must be authorized and authenticated

into the system. The BOLO will be

created, but won’t be shown until its

author confirms its existence through a

link that is being sent to his/her mail.
