Types of Testing

Exploratory Testing

Hands-on testing approach conducted to determine the overall quality level of software and its behavior. It is performed without documentation and preliminary planning.

User Interface Testing

Validates whether the software’s GUI meets specifications as in mockups or detailed design documents. It checks the consistency or duplication of accelerator keys and examines positions and alignments of window objects.

Functional Testing

Black box technique that focuses on testing the software against use cases, requirements and design documents. It ensures that the product has all the required functionality specified in the requirements.

Integration Testing

Identifies issues that occur when individual software units are combined as one component. There are different approaches namely, top-down integration testing, bottom-up integration testing and sandwich testing.

Usability Testing

Performed to evaluate how user-friendly the GUI design is and how easily the client can learn to use an application. In addition to usability, the application should comply with standards such as ISO-9126, ISO-9241-11, ISO-13407, and IEEE std.610.12

Compatibility Testing

Verifies if the application can be executed on different hardware, operating systems, application servers, web servers, emulators, databases, processors, hardware peripherals, different configurations, browsers and their versions.

Negative Testing

Negative testing is a creative process intended to validate the software against invalid data. Commonly, negative testing is referred to as error path testing or failure testing, and it is performed to check how stable the application is.

Performance Testing

Assesses the system’s effectiveness and speed to ensure it produces results within a specified time laid down in performance requirements.

Localization Testing

Checks the software’s compliance with a particular locale based on its cultural and linguistic peculiarities. The software should support a specific language of display, font, date time, currency, etc.

Regression Testing

A process of testing changes made to a system, component, or a group of units. It ensures that the modification works impeccably; is not damaging and imposes no threats to other modules.

Energage and Skelia worked together and built a functional automation framework and many automated tests. They were extremely flexible regarding our engagement terms, desired framework, and choosing the engineers we used. They also supplied manual testing help that quickly learned our systems and adapted to rapidly changing requirements and testing environment challenges.
