This document discusses testing SOAP web services from both a manual and automated testing perspective. It outlines the pros and cons of manual testing, including that it is sufficient for one-time tests when payloads and contracts don't change frequently. However, manual tests are difficult to maintain when the application under test changes. The document then recommends different automated testing approaches using XML as text, DOM, or serialized objects to avoid these maintenance issues and enable early detection of changes. It promotes using tools like WSDL2Java and code generation plugins to prepare client stubs for automated testing.

7. Manual approach – when is sufficient
Valid payloads provided
One time test
The same version of contract
Artifacts (WSDL or client stub classes) not available
8

8. Manual approach – live scenarios
Requests with frequently changes data e.g. Date
Test flow requires dependent webservise calls
Big responses like 5MB to validate

9. Manual approach - tests maintanance
problem
Application under development changes !
Refactoring:
◦ Namespaces
◦ Tag names
Functional change:
◦ Move element
◦ Add element
◦ change schema constraint :
optional/required, order of elements, number of elements, change type or pattern

10. Programming approaches
1.Xml as text – string builders, parametrization, parsers
regex,
2.Xml as DOM – DOM builders and xPath etc
3.Xml as serialized object – OOP and JAXB
11

11. Payload as serialized object
Request validation using schema from WSDL
Get rid of XML as text – lets use OOP
◦ Early and strict change detection - Compiler
Preparing client stub:
◦ java org.apache.axis.wsdl.WSDL2Java
◦ wsimport from JDK
◦ Maven cxf-codegen-plugin
