Functional Testing
Functional testing involves validating the functionality of an application to ensure that the requirements specified by the stakeholders are met. It plays a vital role in the delivery of high quality applications - both large and small and is driven by thorough understanding of the product domain.

Calpine practices a well – structured and robust functional testing methodology which can be easily adapted for a vast array of projects having varying business requirements. Functional testing is introduced in the early stages of the Software Development Life Cycle, wherever applicable, to ensure almost zero defect rates in all the projects delivered to business. The focus is on defect prevention and the modules are delivered to the testing team as and when complete so that the defects can be detected and tracked to closure early in the projects’ life cycle. The testing team prepares optimized test plans, test strategy and test cases. Execution of test cases is done and defects are reported and tracked using bug reporting tools like Jira, Bugzilla and Mantis. The testing team further ensures a 100% functional coverage of the business requirements through the “traceability matrix” approach. The use of a well defined and consistent process for functional testing ensures that the testing is successfully completed within the stipulated time without compromising the quality of the application.

Calpine has the expertise in functional testing of Web Applications, Desktop applications and Client-server applications.

System Testing
The testing of an application is never complete without system testing. System testing is the end-to-end testing of a complete and integrated application. System testing is done to ensure that the integrated application as a whole meets the business requirements.

At Calpine, the testing methodology employed for system testing is based on the type of project. Test plan, test strategy and test case preparation is done by a team of experts keeping in mind the requirement, technology and domain of the particular application undergoing test. The test techniques and processes are developed so as to assure high requirement coverage and defect detection rates.

Regression Testing
Regression testing is a practice of reusing tests so as to ensure that changes done to an application have not introduced defects to the application. In today’s fast paced work, software applications needs to be upgraded to keep up with the business competition in the market. Calpine, therefore, uses strong and broad series of regression testing which helps people to cost effectively manage changes in the application and the risks associated with the changes. A good regression test has always given our clients the confidence to go about making changes in their applications.

The regression testing approach at Calpine is a combination of manual and automated testing techniques based on an established testing methodology. As part of the automation testing, we employ a wide array of industry-standard testing tools like HP QuickTest Professional and Micro Focus Test partner that leverage established methodologies which assures that the application responds in the same way in different conditions even if any changes are incorporated in the application. We do a thorough R & D on the various best practices followed in the industry and come up with a methodology which best suits the application. This has enabled us to create a proven track record of timely delivery of cost effective high quality solutions, thereby, resulting in customer satisfaction and retention.

Automation Testing
Although automation testing can never completely replace manual testing, it can definitely accelerate the testing execution speed and improve the coverage of the software testing especially in case of long-term projects. When an application undergoes change, the tests need to be repeated as part of regression testing and automation testing can be used to perform the tedious task of executing the repeatable tests.

At Calpine, automation frameworks are developed from the perspective of the technology and domain in which the application is developed. To effectively reduce testing cycles, increase test coverage and efficiency of the tests, a dedicated team of automation experts develop robust and well-structured scripts using various automation tools like HP-Mercury Interactive QTP and Micro Focus Test partner. Use of automation testing in the projects has helped our clients in reducing the overall testing costs and timelines.

Integration Testing
Integration testing is a phase of testing where unit tested software modules are integrated with one another and tested to ensure that no defects arise as result of this integration.

Calpine combines domain knowledge with our several years of experience to design integration test plans and test cases which ensure the successful interoperability of various components of the application. These are utilized to perform integration testing to deliver robust products with components which seamlessly integrate with one another.

Web Testing
The internet has evolved into the most preferred medium for carrying out business effectively as it has helped to overcome the constraints of time and resources. Hence, testing of applications based on web is very crucial.

Since Web based applications should have various features like high performance levels, speed, security, and interoperability across platforms, browsers and servers, at Calpine the testing of web applications is performed by testing teams who have experience in successfully testing web based applications.

Performance Testing
Performance testing is done to verify the performance of an application under various workloads. It can also be used to test the scalability, reliability and resource usage of an application.

Performance issues of an application are often detected after the release o f the application. However, the remediation of such issues can prove to be more costly. At Calpine, we understand the need for early detection of performance issues. Our testing services are, therefore, designed to address these issues before release of the application. We develop domain-specific performance testing strategies which are tailored to suit the performance requirements of the stakeholders. A combination of manual and automated testing approach is used to evaluate the performance of the application under varying amounts of load, traffic and usage patterns. The response times are verified to ensure that they meet the required targets and any discrepancy is reported and further analyzed to take appropriate corrective actions.

Calpine has the expertise in testing the performance of a wide range of applications like web applications, ecommerce sites etc.

Compatibility Testing
Compatibility testing verifies the compatibility of an application with the computing environment like different browsers, operating systems, databases, servers, clients, different versions of a software and hardware. This ensures that the application functions properly in the environment it is supposed to operate. The same application may behave in different ways in different browsers, configurations, display resolutions and internet connectivity speeds. To make sure that such defects do not occur in the software and to make the necessary modifications in the application in case such defects have been detected in the application, compatibility testing is performed.

Calpine has the experience of performing compatibility testing on a variety of applications operating in different domains like Life Science, e-commerce and ERP.

Installation Testing
Calpine has the expertise in performing installation testing in a wide range of applications covering various domains. Installation testing is done with the intent of finding any issues that might occur while installing an application. The installation testing procedure at Calpine focuses on ensuring that software will install and uninstall without any issues on all the required Operating Systems.
