ABSTRACT


Interactions spanning multiple organizations have become an important aspect in today’s

collaboration landscape. Organizations create alliances to ulill strategic ob!ectives. "he

dynamic nature o collaborations increasingly demands or automated techni#ues and

algorithms to support the creation o such alliances. Our approach bases on the

recommendation o potential alliances by discovery o currently relevant competence sources

and the support o semi-automatic ormation. "he environment is service-oriented comprising

humans and sot$are services $ith distinct capabilities. "o mediate bet$een previously

separated groups and organizations% $e introduce the bro&er concept that bridges

disconnected net$or&s. 'e present a dynamic bro&er discovery approach based on interaction

mining techni#ues and trust metrics.

"he rapid advancement o enabled inrastructure has undamentally

changed ho$ businesses and companies operate. (lobal mar&ets and the re#uirement or rapid

innovation demand or alliances bet$een individual companies. Service-oriented computingoer $ell established standards and techni#ues to model and implement interactions spanning

multiple organizations. Collaborative service-based systems are typically &no$ledge intensive

covering Comple) interactions bet$een people and sot$are services. In such ecosystems%

le)ible interactions commonly ta&e place in dierent organizational units. "he challenge is

that top-do$n composition models are diicult to apply in constantly changing and evolving

service-oriented collaboration system.

"here are t$o ma!or obstacles hampering the establishment o

seamless communications and collaborations across organizational boundaries* +i, the

dynamic discovery and composition o resources and services% and +ii, le)ible and conte)t-

a$are interactions bet$een people residing in dierent departments and companies. "heories

ound in social net$or& analysis are promising candidate techni#ues to assist in the ormation

process and to support le)ible and evolving interaction patterns in cross organizational

environments. In social net$or&s% relations and interactions typically emerge reely and

independently $ithout restricted paths and boundaries. esearch in social sciences has sho$n

that the resulting social net$or& structures allo$ or relatively short paths o inormation

propagation. 'hile this is true or autonomously orming social net$or&s% the boundaries o

collaborative net$or&s are typically restricted due to organizational units and ragmented

areas o e)pertise. 'e propose social net$or& principles to bridge segregated collaborative

net$or&s. "he theory o structural holes is based on the idea that individuals can beneit rom

serving as intermediaries bet$een others $ho are not directly connected. "hus% such

intermediaries can potentially bro&er inormation and aggregate ideas arising in dierent parts

SYSTE TESTING

"he purpose o testing is to discover errors. "esting is the process o trying to discover

every conceivable ault or $ea&ness in a $or& product. It provides a $ay to chec& the

unctionality o components% sub assemblies% assemblies and@or a inished product It is the

process o e)ercising sot$are $ith the intent o ensuring that the

Sot$are system meets its re#uirements and user e)pectations and does not ail in an

unacceptable manner. "here are various types o test. Each test type addresses a speciic

testing re#uirement.

TY"ES #& TESTS

%nit testing

Anit testing involves the design o test cases that validate that the internal program

logic is unctioning properly% and that program inputs produce valid outputs. ll decision

branches and internal code lo$ should be validated. It is the testing o individual sot$are

units o the application .it is done ater the completion o an individual unit beore integration.

"his is a structural testing% that relies on &no$ledge o its construction and is invasive. Anit

tests perorm basic tests at component level and test a speciic business process% application%

and@or system coniguration. Anit tests ensure that each uni#ue path o a business process

perorms accurately to the documented speciications and contains clearly deined inputs and

e)pected results.

Integration testing

Integration tests are designed to test integrated sot$are components to determine i

they actually run as one program. "esting is event driven and is more concerned $ith the

basic outcome o screens or ields. Integration tests demonstrate that although the components

$ere individually satisaction% as sho$n by successully unit testing% the combination o

components is correct and consistent. Integration testing is speciically aimed at e)posing the

problems that arise rom the combination o components.

&unctional test

4unctional tests provide systematic demonstrations that unctions tested are available as

speciied by the business and technical re#uirements% system documentation% and user

manuals.

4unctional testing is centered on the ollo$ing items*

Valid Input * identiied classes o valid input must be accepted.

Invalid Input * identiied classes o invalid input must be re!ected.

4unctions * identiied unctions must be e)ercised.

Output * identiied classes o application outputs must be e)ercised.

Systems@8rocedures* interacing systems or procedures must be invo&ed.

Organization and preparation o unctional tests is ocused on re#uirements% &ey unctions%

or special test cases. In addition% systematic coverage pertaining to identiy Business process

lo$sD data ields% predeined processes% and successive processes must be considered or

testing. Beore unctional testing is complete% additional tests are identiied and the eective

value o current tests is determined.

System Test

System testing ensures that the entire integrated sot$are system meets re#uirements. It

tests a coniguration to ensure &no$n and predictable results. n e)ample o system testing is

the coniguration oriented system integration test. System testing is based on process

descriptions and lo$s% emphasizing pre-driven process lin&s and integration points.

2hite Bo. Testing

'hite Bo) "esting is a testing in $hich in $hich the sot$are tester has &no$ledge o

the inner $or&ings% structure and language o the sot$are% or at least its purpose. It is

purpose. It is used to test areas that cannot be reached rom a blac& bo) level.



48/71


Blac8 Bo. Testing

Blac& Bo) "esting is testing the sot$are $ithout any &no$ledge o the inner $or&ings%

structure or language o the module being tested. Blac& bo) tests% as most other &inds o tests%

must be $ritten rom a deinitive source document% such as speciication or re#uirements

document% such as speciication or re#uirements document. It is a testing in $hich the

sot$are under test is treated% as a blac& bo) .you cannot GseeH into it. "he test provides inputs

and responds to outputs $ithout considering ho$ the sot$are $or&s.

%nit Testing!

Anit testing is usually conducted as part o a combined code and unit test phase o the

sot$are liecycle% although it is not uncommon or coding and unit testing to be conducted as

t$o distinct phases.

Test strategy and approach

4ield testing $ill be perormed manually and unctional tests $ill be $ritten in detail.

Test o/6ecti5es

• ll ield entries must $or& properly.

• 8ages must be activated rom the identiied lin&.

• "he entry screen% messages and responses must not be delayed.

&eatures to /e tested

• Veriy that the entries are o the correct ormat

• 5o duplicate entries should be allo$ed

• ll lin&s should ta&e the user to the correct page.

Integration Testing

Sot$are integration testing is the incremental integration testing o t$o or more

integrated sot$are components on a single platorm to produce ailures caused by interace

deects.

"he tas& o the integration test is to chec& that components or sot$are applications%

e.g. components in a sot$are system or P one step up P sot$are applications at the company

level P interact $ithout error.

Test Results! ll the test cases mentioned above passed successully. 5o deects

encountered.

Acce)tance Testing

Aser cceptance "esting is a critical phase o any pro!ect and re#uires signiicant

participation by the end user. It also ensures that the system meets the unctional

re#uirements.

Test Results! ll the test cases mentioned above passed successully. 5o deects

encountered.

Conclusion

Conclusion!

In this paper $e introduced the notion o bro&ers in socially enhanced service-oriented

environments. "he idea o our bro&er approach is derived rom theories ound in social

sciences. Bro&ers can be modeled as /uman-8rovided Services to support the seamless

integration o human capabilities in service-oriented inrastructures. "he novelty o our

approach is that bro&ers are not discovered based on static policies or static bro&er

capabilities. In this $or&% $e proposed the discovery o bro&ers based on mining techni#ues

and the automated computation o periodically updated metrics based on interaction logs. "his

not only helps to ind suitable bro&ers but also relevant communities and social net$or&s to

$hich bro&ers are connected to. 4urthermore% $e introduced the Bro&er 0uery and 1iscovery

2anguage +B012, enabling the deinition o discovery and interaction policies.
