FUT Script
Development

2. Agenda
Introductions
Why are we here?
Scripting for
functional
specifications
Review and analysis
of a real functional
specification
Q&A
10/25/11Andy Scarr

3. Why are we here?
To Improve the quality and coverage of the
functional test scripts detailed in the Functional
Specification documents
To understand what value this can add to the
delivery.

5. Why are we doing this?
Provide clear success criteria to the developer
Provides a scenario in which to put the change into
context
Focus’s the Developer on testing the changes
critical to the business
Improves the quality of the delivery into the
subsequent phase of testing
Earlier rather than late identification of defects is
more cost effective.

6. What do they need?
A testable requirement!
Be specific
Provide examples to fill out the required solution
Define the acceptable Ranges / Values / Actions
Define the Unacceptable Ranges / Values / Actions
10/25/11Andy Scarr

7. Be Realistic!!!
It is impossible to test 100% of the changes
Focus on the high risk areas
Focus on the business priorities
Focus on getting an appropriate level of coverage

8. Techniques for Testing
Ranges and Values
Boundary Value Analysis
Looking at the edges of the range
Eg. Range 1-100
Values to be tested: 0, 1,100, 101
Equivalence Partitioning
Looking at valid values within the Range
Eg. Range 1-100
Values to be tested: 2, 99

9. Acceptable Numeric Ranges
A requirement states that a specific field on a Form be populated by a user
manually with a Numeric Range 1-5.
The developer may deliver this as a freeform text solution or via a
dropdown selection, this will impact the required scope of the testing
Tests should be written to cover that:
- 1, 2, 3, 4 and 5 be allowed
- 0 and 6 not allowed
- -1, -2, -3, -4, -5 not allowed
- 1.5, 2.75 not allowed
- Alpha characters not allowed
- Symbol characters not allowed
- Blanks not allowed

10. Acceptable Numeric Values
A requirement states that a specific field on a Form be populated by a user
manually with a specific Numeric codes (5 digits).
The Developer needs to be aware of what constitutes a valid code
Tests should be written to cover that:
- Valid 5 Digit codes should be allowed
- Valid 4 (Correct but incomplete) and 6 Digit (Correct but elongated)
codes not allowed
- Incorrect Codes not Allowed
- Alpha characters not allowed
- Symbol characters not allowed
- Blanks not allowed

11. Finally…..
Effort expended here will have a direct
positive influence on the ultimate quality of
the delivery to the business.

12. Review and Analysis of a
Real Functional
Specification
• Early Retirement Request Form
• Can be completed by either the
employee or the manager online
• Each will see different fields and
pre-populated data on entering the
form
• Dates Displayed / Pre-populated
• Free Text fields
• Checkboxes

14. Things to remember
Pre-populated data
Is it being populated correctly?
Can it be / Should it be amended once populated
Free Text fields
Alpha Only
Numeric Only
Alpha Numeric
Symbols
Checkboxes
Check, uncheck, recheck
10/25/11Andy Scarr

15. Things to remember
Update Sequences
Top to bottom
Bottom to top
Random updates
Date Formats
YYYYMMDD
DDMMYYYY
\ , . /
Dropdowns
Select, Unselect Reselect
10/25/11Andy Scarr

16. Things to remember
Role Variances
Different security Levels having different access
Different views of the same form
Different rights
Conflicts in the Design
Beware a copied forward template!
Non Functional
Performance – SLA to bring the form up and to Save it.

17. Things to remember
Legal Requirements
Is it compliant to the Disability Discrimination Act 1995
