SOA principles

Information system components do not depend on the technical features

of implementation,

Components communicate with each other via open standards,

Using services which do not depend on concrete applications, with the

uniform interfaces of access to them,

Each component, making up the information system implements an

independent, repeatable business function,

Organization of services as loosely-coupled components for system

integration.

WSDL(Web Services Description Language) is an XML-oriented language,

describing a web-service

WSDL?

SOAP?

• SOAP Simple Object Access Protocol

• SOAP is a communication protocol

• SOAP is used for binding between applications

• SOAP is a format for message communication

• SOAP provides communication via Internet

• SOAP does not depend on the platform

• SOAP does not depend on the language

• SOAP is based on XML

• SOAP is easy and extendible

SOAP?

SOAP specification defines an XML- “envelope” for message communication

<soap:Envelope mlns:soap="http://www.w3.org/2001/12/soap-envelope"

soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

<soap:Header>

...

</soap:Header>

<soap:Body>

...

<soap:Fault>

...

</soap:Fault>

</soap:Body>

</soap:Envelope>

UDDI?

UDDI system (Universal Description, Discovery and Integration ) allows

companies to make their web-service available to the public

And what to test?

Business logic. We test to meet the requirements

Standards compliance, if one has used a nonconventional

platform.

Interfaces. Validators and data converters.

Error handling

Why is automation needed?

In most cases GUI is not provided

Reduces the time for testing easy scenarios

Regressive testing has not been cancelled by anyone

Irreplaceable when carrying out load-testing

Methods

QTP

(WSDL for scanning)

Using a WebService object allows to set up a qtp communication process– a web-

service

Known issues:

Microsoft .NET Framework WSE

1. An array in an array as parameters

2. Requests from DIME attachments

Apache Axis

1. Entity objects

2. Conflict of methods names

3. Testing of headers

4. Protected IIS server

Results review

Results review

VerifyXMLFile – compares two XML files;

VerifyXMLValue- checks for tags for the expected result;

ValidateXML – checks an XML file for compliance with thedefined scheme;

OutputXMLValue – returns the value of the defined tag.

To sum up:

The strategy of testing web-services does not differ in any way from testing other

products

Automation is the matter of importance here considering the absence of the user

interface

Any means of automation can suit, it is to your choice which one is better
