Quality Assurance Software Testing

Quality Assurance Software Testing is an integral and critical phase of every software development project. And thus our developers and testers takes special care to ensure that the newly developed products or product enhancements meet all the functional and performance requirements and that those products are reliable and able to operate consistently under peak loads.

It is most effective to start testing early in the development cycle and to test iteratively, with every build. With this approach, defects are removed as the features are implemented. And as a result the product is ready for release much earlier.

The Testing process focuses primarily on evaluating or assessing product quality, which is realized through the following core practices:

• Find and document defects in software quality.
• Advise on the perceived software quality.
• Validate and prove the assumptions made in design and requirement specifications through concrete demonstration.
• Validate that the software product works as designed.
• Validate that the requirements are implemented appropriately.

Testing is applied to different types of targets, in different stages or levels of work effort. Testing is usually done at two levels:

Developer Testing

Developer testing denotes the test design and implementation most appropriately performed by the team of developers. The developers create their tests in such away so as to make them available to independent testing groups for execution.

Independent Testing

Independent testing denotes the test design and implementation most appropriately performed by someone who is independent from the team of developers.

The other levels include:

• Independent Stakeholder Testing - testing that is based on the needs and concerns of various stakeholders.
• Unit testing - testing that focuses on verifying the smallest testable elements of the software.
• Integration testing – testing to ensure that the components in the implementation model operate properly when combined to execute a use case.
• System Testing – testing to ensure that the system's end- to-end functioning elements operate properly.
• Acceptance Testing – testing to verify that the software is ready, and that it can be used by end users to perform those functions and tasks for which the software was built.

J2EE programming

Having being strongly focusing on coding and programming services, Cogent not only delivers comprehensive solutions but also bolsters your existing development unit by writing tailor-made code for your varied software development projects. Programmers at Cogent are skilled, competent and fluent in Java Software services.

Java has emerged as a leading software development platform based on its modular, component-oriented architecture and that’s the reason behind it’s wide acceptance as one of the top choice for providing enterprise application development in the software industry. The most common reason for adopting Java is that it simplifies development and deployment, also reducing time and costs. It offers companies portability and scalability to meet changing business needs. J2EE promotes Programming in Java resulting in Java-centric computing, and all components deployed into a J2EE deployment (like EJB components and Servlet) must be written in the Java language. Other languages can be bridged into a J2EE solution through web services, CORBA, JNI, or the JCA.

Cogent ensures the highest application quality and shortened development cycles by employing best-in-class J2EE application framework.

Cogent will not only assist you in architecting, developing, deploying and maintaining your open standard infrastructure solutions based on J2EE framework but will also provide Java consulting services (Business Consulting, Technical Consulting and Implementation Consulting ) for successful implementation of J2EE based solutions at your organization.

The most common reason for adopting Java is that it simplifies development and deployment, also reducing time and costs. It offers companies portability and scalability to meet changing business needs. J2EE promotes Programming in Java resulting in Java-centric computing, and all components deployed into a J2EE deployment (like EJB components and Servlet) must be written in the Java language. Other languages can be bridged into a J2EE solution through web services, CORBA, JNI, or the JCA.

The wide acceptance of the J2EE platform in the software industry is evidence of its status as a platform of choice for enterprise application development.

J2EE offers several features that accelerate time-to-market. For example, state management services enable developers to write less code and not worry about managing state, resulting in a higher degree of rapid application development. State management services enable you to build components that hold state. Persistence services (entity beans) enable developers to write applications without coding data access logic, resulting in leaner, database-independent applications that are easier to build and maintain. Programmatic transactions allow you to have greater transactional control. And custom tags are extremely powerful, and empower developers and web designers to easily collaborate.
