Regression Testing
It is another famous mechanism for software testing that is used for confirming that a recent code or program change will not affect the major existing features of the application. Regression testing is regarded as a partial or full selection of test cases that have already been executed. These test cases are re-executed towards ensuring the fact that overall functionalities are working fine. Regression testing is performed towards ensuring that new code modifications should not have any side effect on the existing functionalities.
-
Sanity Testing
Regarded as the subset of regression testing, Sanity testing is carried out for ensuring that the code modifications are working properly. Sanity testing is regarded as a restriction for checking whether or not testing for the given application can proceed. The primary focus of sanity testing during the process is aimed at validating the overall functionality of the application. As such, it is not any type of detailed testing. The major functionality of this type of testing is to analyze that the proposed modifications are working as per the expected results.
-
Usability Testing
Usability testing is a mechanism to observe how to use a particular tool for testing a software application with the real users. This type of testing is used for evaluating the fact that how easy a particular software application is on a functional basis. The test is known to take place with the real users for measuring how intuitive or usable the given software solution is.
-
Mutation Testing
Mutation testing is defined as a type of specialized software testing solutions wherein the users are known to mutate or change specific statements in the application’s source code. Mutation testing is known to check whether or not the test cases are able to detect the errors. It is a specific variant of white box testing –typically utilized for unit testing. The modifications in a typical mutant program are maintained extremely small. Therefore, there is no change in the overall objective of the program.
-
Performance Testing
As per the definition of professional performance testing services, this type of testing is a specialized software testing towards ensuring that software applications are performing well even under unexpected workload. The primary focus of performance testing solutions are aimed at checking the stability, scalability, and speed of the given software program.
