What is Aerial?

erial is an engine generating test cases based on

requirements description

Key principles in requirements design

Typical generation patterns

Tests generation flow

How does it work?

Typical functionality requires typical tests

Test data can be generated based on format knowledge

The tests flow can be represented in common form

Key principles in requirements design

Typical functionality requires typical tests

Test 1: Valid InputTest 2: Invalid Format InputTest 3: Mandatory Fields Are EmptyTest 4: Unique Fields

The types of test scenarios are pretty similar

Test 1: Valid InputTest 2: Invalid Format InputTest 3: Mandatory Fields Are EmptyTest 4: Unique Fields -> No unique fields

Test data can be generated based on format knowledge

Input Format: \((\d+)\) (\d{8,9})

Valid Input Invalid Input

• Matches format: (44) 345637687 • Improper format: (32) 1123 (34) 17• Empty value:• Non-numeric value: abcdefg

We can use just the format

Another format definition examples

Any text: (.*)

Numeric Range: (0; 100)

Date Range: [01-01-2000;02-10-2010), Format: dd-MM-yyyy

Enum: (Winter|Spring|Summer|Autumn)
