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
