5) Accountability Testing

Results throughout the responsibility of testing must confirm the functionality of the system. Otherwise, it is a failure. The work must always generate the deliberate outcome for which it was deliberate.

The work must always create a deliberate outcome for which it was deliberate.

6) Reliability Testing

The testing believes that the software system functions perfectly within the determined considerations, compelling a specific period and handles to run. The reliability test will also be ineffective if the system fails to perform under specific scheduled conditions, such as confirming the reliability of all web pages and links.

For reliability tests, the tools of Test-retest and inter-rater.

7) Efficiency Testing

Effective Testing evaluates and assesses the consumption and constraint of resources during the development of a software system.

WebLOAD and LoadNinja are the tools to use for Effective Testing

8) Volume Testing

Volume testing, furthermore, described as flood testing, is a software testing procedure that measures the performance of a system by subjecting it to a large amount of data in the database.

Tools Used for Volume Testing are HammerDB and JdbcSlim

9) Recovery Testing

Recovery testing evaluates the competence of an application to recapture from crashes, hardware failures, and similar issues by intentionally causing software errors in various ways.

Recovery Testing tools are Box Backup and Bacula tools.

10) Responsive Testing

Assess your design across several screen breadths for a legitimate test of adaptivity, rather than depend on predefined screen widths. Test the responsiveness of your user port with Design Modo by modifying the screen width in real-time after entering the website’s URL.

The top goal is to guarantee a seamless experience on several digital devices, as technology continues to play a critical role in our daily tasks due to its suitability.
