Approach & Methodology

QA Testing Methodology is precisely defined at Interworld. Project Management, Maintenance of Time Schedules, Quality Assurance, and Software Engineering are some of the key areas we focus on in the Software Development Life Cycle process. Our exhaustive Methodology ensures thorough and effective QA Testing of the software products and applications.


Data Integrity Testing
Data integrity testing, a key component of QA testing, has to do with verifying the reliability of data procurement and storage methods in order to ensure that the data obtained is in the required format, and that it is reliable and consistent with the data expected to be present in the database. Data Integrity Testing also ensures that all relevant information is stored in a timely manner, thus avoiding data loss, which has the potential to prove catastrophic to a business. Parameters can also be customized as per client requirements for the data integrity testing during the setup phase.


Functionality Testing/Defect Analysis
A thorough review of a client's application needs and of their existing systems helps us develop the Functionality tests. These tests are performed by Interworld on the basis of our systematic methodology for Internal Documentation, Reporting, and Resolution of defects and bugs detected during the various testing processes. The analysis of these defects and bugs are carefully documented to provide our clients with: A Complete description of the bug/defect and the process of reproducing it A clear assessment of the usability of the product and its relation to the business objectives Critical data and information needed by the developers involved in debugging. This involves a cost/benefit trade off.


Performance Testing
Performance testing involves testing the product on the basis of the following criteria and other Custom criteria as required by the Client:


Stress Testing
In Stress Testing, the parameters typically tested are: Storage, Computing Time, Communication Capacity, and Database Recovery Time. This process drives the system to the very limits of its endurance in order to determine what features in the application design can fail during implementation. The features that do fail can turn out to be defects capable of causing disastrous failure.

Availability Testing
Availability testing involves testing the reliability of the network, database processor, memory, etc. This involves testing the capability to have the support for critical data required by the applications to be up and running in minimum standard conditions. All the architectural components that need to be available are also made sure to be present and functional.


Response/Throughput Testing
Response/Throughput testing is used to test the load-bearing capacity of the system and to measure the response time and throughput of the various components of the system.

Compatibility Testing
Usability testing is concerned with evaluating a system’s ease of use and the level of convenience it provides to non-technical people to enable them to utilize the various tools and functionalities offered by the system. This helps users derive the maximum benefit from the system. Usability Testing further entails detailed analysis of the navigation system, the user interfaces, etc. General Usability testing also involves the following:

Authentication
GUI forms and selections such as:
Text Boxes
Radio Buttons
Check Boxes
Drop Down List Boxes
Combo Boxes
Screen Validations/Validation Conditions
Navigation Conditions
Usability Conditions
Other Generic requirements
Preferred QA Testing Model


Onshore/Offshore QA and Testing
Interworld’s Global Delivery Model combines the advantage of offshore software development with direct control over the project onshore. In this model our onshore business staffs liaise with our clients, while the development staffs are based offshore. Clients benefit by this model in the following ways: Onshore test/plan/design team in direct communication with client development team.
Effective communication between client and offshore team ensured.

Time efficiency
Offshore team can work for more than one shift if required.
