Agenda
Introductions Why are we here? Scripting for
functional specifications
Review and analysis of a real functional specification
Q&A

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.

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.

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

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

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

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

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

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

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

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
04/13/23Andy Scarr
Things to remember
Update Sequences Top to bottom Bottom to top Random updates
Date Formats YYYYMMDD DDMMYYYY \ , . /
Dropdowns Select, Unselect Reselect
04/13/23Andy Scarr
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.

Things to remember
Legal Requirements Is it compliant to the Disability Discrimination
Act 1995
