HAPPY TESTING...! When it comes to Big data testing, performance and functional testing are the key. In Big data testing QA engineers verify the successful processing of terabytes of data using commodity cluster and other supportive components. It demands a high level of testing skills as the processing is very fast. Big Data Testing Strategy Testing Big Data application is more a verification of its data processing rather than testing the individual features of the software product. When it comes to Big data testing, performance and functional testing are the key. In Big data testing QA engineers verify the successful processing of terabytes of data using commodity cluster and other supportive components. It demands a high level of testing skills as the processing is very fast. Processing may be of three types Along with this, data quality is also an important factor in big data testing. Before testing the application, it is necessary to check the quality of...

   SERVICE ORIENTED ARCHITECTURE Testing is a Testing of Service Oriented Architecture (SOA) which is an architectural style in which the application components are designed to communicate via communication protocols typically over a network. SOA testing methods Business scenario driven data based testing, Various business aspects related to the system should be analyzed. Scenarios should be developed based on the integration of Various Web services of the application Web services and application. Data set up should be done based on the above scenarios. Data set up should be done so as to cover end to end scenarios as well. Stubs Dummy interfaces will be created to test services. Various inputs can be provided through these interfaces, and the outputs can be validated. When an application uses an interface to an external service, which is not under test (third party service), a stub can be created during integration testing. Regression test...
