VISTADOS offers a wide range of Software Testing Life Cycle (STLC) services, from test requirements analysis through tool identification, test planning, team planning, test scheduling, test scripting, test execution and test results analysis to detailed reporting.

VISTADOS employs the highest standards in the industry to ensure the reliability of the system we test, and we help customers roll out bug-free products in the shortest possible time-every time.

Functionally Testing

Functionality Testing reveals issues related to a product's functionality and conformance to stated/documented behavior, VISTADOS employs industry standard testing techniques to thoroughly test the functionality of the software against its documented specifications. Functional Testing includes the following:

  • 4 Unit (or class) Testing
  • Integration Testing
  • System Testing

Browser/Platform Compatibility Testing

The purpose of Compatibility Testing is to reveal issues related to a product's interaction with other software (operating systems, browsers, installed applications) as well as hardware (video cards, sound cards, processors). VISTADOS evaluates the software product both visually and functionally against all browsers, operating systems, connection types, speeds, ISPs, other hardware software, as applicable.

Website Testing

VISTADOS employs the same functionality and Compatibility Testing disciplines described above toe ensure that the world sees an organization's website exactly as it was designed it to be seen.

Performance Load Testing

Stress Testing is designed to reveal issues related to a product's performance under extreme/non-normal operating environments (low system resources, heavy load, etc.) as well as to quantify the stree level at which a system's response significantly degrades. Using sophisticated software tools, VISTADOS stress tests an application by increasing the load on the application to any desired level.

Automated Testing

Automated Testing aids in the overall testing effort and can supplement the manual testing process and provide valuable insight in a speedy, objective way. VISTADOS's engineers are certified in the use of sophisticated automated testing tools designed to create a repetitive and controlled testing environment.

Regression Testing/Validation

Regression Testing ensures that previously detected and fixed issues really are fixed, do not reappear, and that new issues are not introduced into the program as a result of the changes made. Regression testing is automated using tools.

Manual Testing

Manual Testing is still the ultimate quality ensuring process. VISTADOS includes Manual Testing in its STLC methodology in unit testing, integration testing, use case testing, scenario testing and UAT testing, in addition to automated testing methods.
