Testing and Quality Assurance Components
Testing and Quality Assurance Process
Testing and quality assurance are an important phase within the
systems development life cycle (SDLC). The following is an
overview of this phase of the development and implementation
process:
· Types of testing:
· Unit or component test: This is testing that is conducted on
individual components of a system, such as a piece of code,
program, or module, to check that the functions that each
component is supposed to perform are correct.
· Integration test: This is testing is conducted at a subsystem
level, or a set of components, to make sure the functions or the
processes that they support are functioning properly.
· System test: This is testing is usually conducted after several
other phases of testing have been completed, including
component or unit testing, user interface testing, integration
testing, and so forth. This is a complete test of both software
and hardware specifications.
· User acceptance test: This is testing that is conducted by the
customer to ensure that it meets the specified requirements by
satisfying the acceptance criteria.
· Other types: These can include beta tests, compliance tests,
conversion tests, interface tests, performance tests, and many
others.
· Test planning components and guidelines:
· Test cases: These are scripts for the tests that will occur.
· Acceptance criteria: These are established from requirements
in measurable or testable terms.
· Quality: This includes goals such as reliability, efficiency,
accuracy, and ease of use.
· Methodologies: These are types of tests and environments
where the tests will be performed.
· Testing environment: This includes the hardware, software,
and test tools required for performing the tests.
· Testers: These are the personnel who will conduct the tests.

· Error reporting and tracking: This is a mechanism to record
and track errors.
· Completion criteria: These are requirements that must be met
for sign-off on the particular test phase.
· Detailed test schedule: This is a detailed project plan for
testing.
· Testing life cycle steps:
· Requirement phase: This includes tests that are tied to
requirements.
· Test planning phase: Tests are planned in parallel with project
planning.
· Test analysis phase: This is where people analyze the tests that
are needed.
· Test design phase: This is where people design tests in
parallel to system design.
· Test verification: This is where people verify that the test
scenarios or case designs provide full test coverage.
· Regression testing: This is where people verify that the
individual components work together as a system.
· Test execution phase: This is where various tests are run.
· Result analysis phase: This is where people evaluate the
results of the test.
· Bug tracking and reporting phase: In this phase, any errors
need to be recorded and tracked.
· Rework phase: This phase fixes the errors that need to be
fixed and retested.
· Final test and implementation phase: This is the final system
test in operation before go-live, and it includes another test
once you are live.
· Quality assurance components:
· Standards: These are the standards surrounding
documentation, reviews, coding, comments, and testing.
· Tools and techniques: These are the tools that ensure that
quality standards are met.
· Measures and metrics: These are the measurements and
metrics to track how the quality standards are being met.

· Controls and sign-offs: These are the controls that are in place
to not exit a phase until the final sign-off and approval.

Development Model Comparisons
The following is a comparison of five computer-aided software
engineering (CASE) diagrams, including their components and a
description of their strengths and weakness:
Use Case Diagram
The use case diagram has the following components:
· It uses cases to show the sequence of actions.
· It shows actors, such as person, group, organization, or
external system that play a role in interactions within the
system.
· Associations or communications represent interactions
described by the model.
· System boundaries show the area for functionality and scope.
This diagram is described as a system or software development

life cycle (SLDC) with defined phases.
The diagram has the following strengths:
· It provides a very high level of representation of the system or
application as a whole, including scope.
· Is a very good communication vehicle for capturing user
requirements and communicating them to the users and
stakeholders.
The weakness of this diagram is that it requires other types of
diagramming techniques to provide the drill-down detail.
Object Diagrams
The object diagram can be described as a rapid application
development (RAD) that supports faster software development
and uses a quick requirements-gathering phase. It goes into
prototyping to further define requirements based upon user
feedback on the prototype.
The strength of this diagram is the time to market is greatly
reduced for graphical user interface (GUI) or Web-based
applications.
Because it is so quick, proper testing is not always conducted.
The prototypes are generally throw-away code.
The Data Flow Diagrams
The data flow diagram (DFD) has the following components:
· It uses squares or ovals to represent external entities,
terminators, sources, or sink.
· Circles or rounded rectangles represent processes within
system.
· Arrows represent data flows.
· Open-ended rectangles represent data stores.
Data flow diagrams illustrate the processes, data stores, and
external entities in a system and the connecting data flows.
Strengths of this model include the following:
· It models real-world entities and methods.
· It is excellent in supporting reuse.
· It uses class diagrams to represent the model.
To help the customers understand the requirements that they
share, this model is complex to develop.

Entity-Relationship Diagram
The entity-relationship diagram (ERD) has the following
components:
· Entities represent objects in the real world.
· Relationships represent connections between entities.
· An associative object type indicator can represent both an
object and a relationship.
· The subtype and supertype indicator represent subcategories
by a relationship.
Entity-relationship diagrams are a form of a network model to
represent the data within a system or application. Relationships
show how data are represented by entities and logically related.
The strength of this diagram shows the relationship between the
various entities within a system.
This diagram does not reflect sequence or activities within the
system—only the data.
Structure Charts
The structure chart has the following components:
· Boxes represent functions or modules.
· Lines represent the linkage between functions and modules.
This diagram is a top-down modular design that depicts
identifiable functions and the modules underneath or shows the
functional decomposition.
The strength of this diagram is to provide a way of decomposing
an application or system into manageable modules.
This diagram does not provide a lot of detail about the actual
functions that will be performed in the system.
