The document outlines a testing project for Ryvuss, an intelligent search engine used by Carsales.com.au. The testing team includes Tapan Mehta, Atulya Aravindan, and Syeda Sharfunnisa. They propose using metamorphic testing to address oracle problems, category partition testing for test case design, and adaptive random testing for test case generation. The objectives are to propose a testing methodology and design test scripts to help refine Ryvuss search criteria.

4. Ryvuss Search Testing Project
 Testing Ryvuss search engine built by
Carsales that powers all their classified
and mobile Apps in Australia, Brazil and
Korea.
What is Ryvuss?
 Ryvuss is an intelligent search engine
designed in such a way that it easily
indexes data from any sources either in
cloud or from dedicated data centres and
can handle and maintain complex
searches allowing custom refinements.

5. Current Problems
Currently there are two problems associated with Ryvuss
search:
 Oracle & Automation problem
 Test Case Generation

6. Objectives
 To propose a testing methodology which will assist carsales.com.au
to refine their search criteria in Ryvuss.
 To design test scripts that can be used for functional
Implementation.
 Analysis report for future references.

7. Testing Methodology Proposed
 Metamorphic Testing – To Overcome Oracle problem
 Category Partition Method – To design Test Case Specifications
 Adaptive Random Testing – Test Case Generation

8. Metamorphic Testing
 Technique used to create follow up test cases bases on existing test cases.
 Mainly done to alleviate the oracle problem
 Checks relations among several executions rather then correctness of
individual outputs.
 Three main steps involved in metamorphic testing:
 Construction of Metamorphic relations
 Generation of follow up test cases
 Execution of Metamorphic tests
8

9. Example
 Assume, A as a Make - Holden
 A1 as a subcategory (Model) of Holden – Commodore.
 Now logically, as any Make is a Parent node of any Models
in Ryvuss Search Engine, the Overall Count of Make must
be always equal to Total Sum of individual counts of
models.
 I.e. Count (A) = Sum of Count (a1 + a2 + a3 + ………… +
an)
 And,
 Say, Count (X) = Count (A and A1)
 Then, the metamorphic relation can be formed as:
 Count (X) <= Count (A)
 Where, Count (X) = Result Count on selecting Holden and
Commodore
 Count (A) = Result Count for Holden.

11. Category Partition Method
 It is a black box testing approach.
 A method that goes from Specifications(Description of the system , to a
test) that are analysed and test cases are built.
 It’s a 6 step approach :
 Identify independent testable feature
 Identify categories
 Partition categories into choices
 Identify constraints among choices
 Produce/ evaluate test case specification
 Generate test cases from test case specification

13. Adaptive Random Testing
 It is a black box testing method.
 It is simple and can be easily implemented
 Test cases are chosen randomly
 As it depends on the failure rates it is not considered to be a powerful testing
method.
