The ultimate deliverable from any testing effort is software that has fewer bugs than before the testing. In order to understand the value of specific testing activities for use in planning necessary revisions to the software, additional details should be provided in the form of:

Acceptance testing verifies the application conforms to functional and programming specifications in "live" configuration environments.

Our domain knowledge has led us to work with client's right from the Requirement Definition stage and to effectively participate and manage the user acceptance testing process. Starting with the Business Requirements document, the Black Box approach is utilized to produce full-coverage end-to-end business scenarios to uncover critical defects.

The functional test cases can be used to develop the acceptance test plan. All or a portion of the workflow scenarios may be included for the user community or representative user to execute. Acceptance criteria for the success of this phase must be either quantitatively or specifically defined. Wherever required, test beds are created using in-house tools to simulate large volumes of data. The entire user acceptance testing approach is from the business user perspective to ensure the system satisfies user requirements.

The purpose of performance testing is to measure the application under load conditions. Another name for performance test is capacity test. The performance requirements and objectives are quantitatively defined in the Business Requirements Document. These quantitative expectations are measured during the test effort. Performance is usually defined in terms of throughput, response time, and availability. Performance testing often incorporates parts of stress testing; therefore, they are combined in this test phase.

The core process involves laying down criterion for validations and measurements that enhance the application's performance. The criterion is arrived after a thorough understanding of system requirements and end-user experience.

Performance tests can be done manually or simulated using performance and stress testing tools. Manual type of test requires that:

At Data Clarity, we've implemented numerous successful automated test systems at many companies, from e-commerce web to clients/server database applications and from financial & mission-critical to multimedia & networked applications.

Automation Testing can evaluate your product, determine the feasibility of automating test types and feature areas, and make recommendations regarding the scope of the effort. We can help you decide:

Regression testing verifies new versions of the software have not adversely affected previous working functionality and that known problems that were fixed have not resurfaced. Regression testing occurs throughout the entire software development lifecycle. Anytime a change is made to the application the area the change was made in must be tested as well as any other areas or interfaces that may also be affected.

Regression Testing ensures proper behavior of your application, including navigation; data entry, processing, and retrieval after fixes or modifications have been applied to the software or its environment.

Regression testing is the most labor-intensive part of software testing; therefore, an automated tool is used. The module dependencies are also captured and documented to ensure that the correct modules are tested when a dependent module is changed. This improves the effectiveness of regression and integration testing.

We build Regression Test suites that are executed while testing the enhancements to ensure that the change in code does not change existing functionality. Regression test suites could be executed manually or with the help of an automated tool. It helps our clients to reduce overall maintenance testing costs and timelines.

We have engaged with Product Companies to maintain and continuously run comprehensive test suites to ensure that every product release is defect free and complies with stated features and requirements.

Security testing determines how well your system protects against unauthorized internal or external access or willful damage.

Security testing tests the application against unauthorized internal or external access, willful damage, etc. Usually, the tester of an application or a system ensures that the application or system being tested is doing what it is supposed to do. To ensure that security testing done at Data Clarity is adequate, effective, and fool-proof, we adopt sophisticated testing techniques. This technique involves giving constantly invalid inputs and corrupted data, checking for buffer overflows during runtime, etc. While testing, we also keep in mind the usability aspect so that implementation of security does not restrict flexibility, which may irk the end user.

Compatibility Testing evaluates how well your software performs in a particular hardware, software, operating system, browser, or network environment.

Data Clarity's Quality assurance services can provide an organization with a cost-effective means to validate an application's functional performance on a wide range of platforms. Our experienced engineers and consultants test web applications, client/server applications, and wireless applications against a variety of databases, servers, operating systems, browsers and hardware/software configurations.

We can execute entire functional and regression test cases set against the configurations chosen by the client or select a subset of key functionality that is to be checked against a host of other configurations.

Configuration management is a discipline that ensures the integrity of all components involved in designing, developing, testing, deploying, and maintaining any system. Configuration testing encompasses testing various system configurations to assess the requirements and resources needed. We check whether your site has the proper look and feel on all supported browsers and operating systems and do all the user interface controls and plug-ins function correctly on all configurations.

We can execute test case set against the configurations chosen by the client or select a subset of key functionality that is to be checked against a host of other configurations. Testing activities are buttressed with detailed reports, which reflect our testing results and observations of the application's behavior under various conditions, configurations and platform combinations.

Our configuration management strategy focuses on three CM disciplines:
  Version and build management - Version management manages the integrity of the items that have been logged as being under version control by the configuration management system. These items can be source, binaries, user documentation, requirements, specifications, etc
  Release management - Processes need to be established to assist in the determination of which software build should be flagged as the release candidate, processes for concurrent development of subsequent phases, and appropriate tagging methods of which build is the release build in the CMS.
  Change management - Changes to software or documentation need to be controlled by a change management process. The purpose of change management is to minimize the impact a change will have on current development and ensure changes are made in an orderly fashion.

A standard CM solution provides many benefits such as:
  Improve the complete software development and maintenance cycle.
  Make testing and QA easier.
  Remove error-prone steps from product release management.
  Provide traceability of related components.
  Automate the CM processes and procedures.
  Improve change management and problem tracking challenges.

Did you know that 20% of the population is considered disabled? Did you know that the government requires that all electronic and information technologies used by Federal agencies be accessible to all people, including those with disabilities?

Physical disabilities, such as mobility barriers, are usually easy to recognize. It's the other disabilities, such as language and literacy impairments, that often go unrecognized. People working in these constricted environments need to access technology in a different fashion we can help you to determine what special accessibility options are needed in your design and/or assess the effectiveness of existing options. No matter what constraints your customers operate under, we can help you to ensure their comfort, productivity, and enjoyment of your product.

With the help of load testing, it's possible to determine how effectively your Web site or application will accommodate an increasing user load.

Load testing is an essential, but often neglected part of the development cycle. By modeling and simulating real-life demands, critical performance and scalability issues can be identified and eliminated. Without a load testing analysis, there's no way of knowing what might happen when your Web site or application has to function under a heavy load.

Data Clarity removes the guesswork from your process, helping you predict system behavior and performance by:
  Exposing Bottlenecks Early On
  Accelerating Product Deployment
  Maximizing Productivity
  Pinpointing Scalability & Performance Concerns
  Comprehensive management reports and metrics will help clarify problems and keep the testing progress out in the open.
