S&*t%a$e Agent,A software agent is a computer program that works

toward goals in a dynamic context on behalf of

another entity (human or computational), perhaps fora long period of time, with discontinuous direct

supervision or control, and exhibits a significant

flexibility and even creativity degree in how it tries to

transform goals into action tasks

an agent do searches for us* he agent would typically be given a uery that would reuire

Unit Testing In MAS

Unit testing is a s&*t%a$e development process in

which the smallest testable parts of an application,

called units, are individually and independently

scrutini+ed for proper operation& Unit testing is often

automated but it can also be done manually&

#t is a role based approach, we can find out the individual behavior of agents&

his approach doesnt create complete test cases, it needs to be combined with

other strategies to make a thorough set of test cases&

his approach only tests individual agent, group testing of agents or system of

agents as a whole is not considered&
