Testing Flashcards
Before going live with a hospital information system, the system should be thoroughly tested to assure that it is operating properly.
System Test Plan
The system test plan consists of the following four steps:
Develop the overall test plan.
Create the test scripts.
Carry out the testing
Troubleshoot and system’s failings as soon as possible
will help to define the problem(s) that the new information system is expected to address.
A feasibility study
It will also answer questions regarding cost, goals, and specific outcomes.
A feasibility study
are software applications, such as those commercially available or prepared by third parties, which need to be integrated into the other software of the information system.
Components
completed to determine if the software meets specifications and functions properly and whether it meets interaction requirements of the system.
Testing
May be tested by the developer and by the user
Components
are parts of a component with predictable properties.
Features
the term used to describe the addition of more and more features to a program.
Feature Creep
Features may include the following
Management of database
Ability to generate reports.
Ability to integrate with other components of a system and scalability
E-mail and other customizable alerts.
Time keeping/login and logout times.
Communication among different levels and multisite capabilities.
Real-time processing.
Ability to establish uniform procedures.
Ability to provide feedback
a computer program that allows two or more programs to exchange information.
Interface
If the connection is direct, the interface is ______
Point to Point
allows transfer of data only between two programs
Point to point interface
allows information to transfer from one system to a number of different systems.
Interface Engine Software
a de facto industry standard, although different vendors have different configurations.
Serial Peripheral Interface (SPI)
allows master/slave communication from the master device to single or multiple slave devices
SPI
full duplex and facilitates communication in both directions simultaneously.
SPI
facilitate communication in both directions but only in one direction at a time.
Half duplex interfaces
used to communicate with a variety of peripheral devices, such as sensors, clocks, liquid-crystal displays, universal serial bus ports, and communications
SPI
human–computer/machine interface
User interface
allows interaction between the user and the machine (e.g., computer, other electronic devices), permitting the user to make input and to see outputas a result.
User Interface
The design of this interface must consider the needs of the user and ease of use.
User interface
Current and new interfaces include:
Touch screens and touch user
Graphical user
Gesture
zooming
Voice user
natural language
Zero input
Often used in simulations, the device has a combined use of input and output.
Touch screens and touch user
This allows an interface between devices, such as the keyboard and computer. It includes object-oriented user interfaces as well as application-oriented interfaces.
Graphical user
This allows input from gestures and mouse/stylus movements.
Gesture
This allows changes in scale of output.
Zooming
Input is by keystrokes or voice commands, and output is by voice commands.
Voice user
This allows input by keystrokes in natural language (e.g., questions), and output is the response.
Natural Language
Input derives from sensors.
Zero - Input
highlighted words, icons, images
Links
allow access of information at one point from a different point.
Links
must be tested individually to ensure they function properly.
Links
keyboards, mouse, microphone, stylus, webcams
Input devices
terminals, printers, projectors, and screens
Output devices
Devices can be in four different states when connected to a system:
Undefined
Defined
Available
Not available/ stopped
The system does not recognize the device.
Undefined
Information about a specific device is present in the database but not available to the system.
Defined
Information about a device is present in the database and configured to the operating system.
Available
Information about the device is present in its driver, but the device is not available.
Not Available/ stopped
these should be assessed for accuracy.
Reports
These reports contain data about the system itself, including hardware and software, as well as workstations and servers. May be generated by systems or data sets.
Configuration
Often include built-in templates and provide fact-finding to glean information from databases.
Informational
Usually are automated, showing changes that occur in the system over a period of time.
Change
Usually are automated to show how the system or elements of the system compare to a baseline.
Baseline
These reports show summaries of actions, processes, and data.
