Tools for Automating Verification and
Validation
Validation: checking: Are we building the right system?
Verification: checking: Are we building the system right?
•
•
•
Model dependent
size dependent
platform dependent
Purpose: improve the S/W development process
•
•
•
•
•
•
•
- avoid delays, reworks
less error-prone
more standard
better defined
more predictable
faster (time-to-market)
better managed process
assist in better understanding product (helping to manage
complexity of product)
Automating V & V in the S/W
Development Process
Must be at SEI CMM Level 3 or higher.
(- process is defined)
[pre-condition for use of tools]
e.g.
Reqts.
High Level

BUT only automate
where necessary

Level 4 CMM
- metrics to help in
process management
 taking the process view for V & V tool assessment,
1) Where in the process does the tool apply?
2) What is the entry criteria to the use of the tool(set)?
3) What is the exit criteria (for stopping the use of the
tool?)
Ed Kit’s Tool Classifications
Tools for reviews and inspections
- assist in reviews, walkthroughs and inspections of
requirements, functional design, internal design, and code.
- Complexity analysis
- “20% of code causes 80%of the problems” (Pare to
principle) [not good predicates of bad code, easy to collect $]
- Code comprehension
- help to understand unfamiliar code (take an unbiased look)
- Syntax and semantic analysis
- extensive error checking to find errors a compiler would
miss
- flag potential defects
Tools for Test Planning
- define the scope, approach, resources and schedule of testing
activities
- tools required are:
- templates for test plan documentation
- test schedule and staffing estimates
- complexity analyzer

Kit’s Tool Classifications (2)
Tools for Test Design and Development
• detailing the overall test approach specified in the test plan for
software features or combinations of features, and identifying
and prioritizing the associated test cases.
• Not much tool support
• types of tools required:
–
–
–
–
test data generator
requirements-based test design tool
capture/playback
coverage analysis
Test Execution and Evaluation Tools
• process of executing test cases and evaluating the results
– includes selecting test cases for execution, setting up the
environment, running the selected tests, recording the execution
activities, analyzing potential product failures, and measuring the
effectiveness of the effort.
•
Types of tools required:
–
–
–
–
–
capture/playback
coverage analysis
memory testing
simulators and performance
regression testing - necessary
Kit’s Tool Classifications (3)
Software Testing Support Tools
• tools that lend overall support to the overall test process
• when these tools are of poor quality or non-existent the
professional tester suffers
• types of tools required:
– Problem management
• defect tracking tools, etc., used to record, track, and
assist with the management of defects and
enhancements throughout the lifecycle
• Configuration management
– manages, controls and coordinates changes to
documents and other artifacts
Questions before tool acquisition
•
•
•
•
How do the tools fit into and support our test process?
Do we know how to plan and design tests?
Who will be responsible for making sure we get the proper
training on our new tool?
Who will promote and support tool use within the organization
on an ongoing basis?
