Operating system compatibility testing linux, mac os, windows. I when you design a partition as a test designer you are deciding want to treat as equal. The abovementioned software testing types are just a part of testing. Modelling the input domain i partitioning characteristics into blocks and values can be creative.
It is a software testing technique in which the output of a system has to be tested with a minimum number of inputs in such a case to ensure that the system does not accept invalid and out of range input values. In this method, the input domain data is divided into different equivalence data classes. First, a system is partitioned globally, and only then it is partitioned locally. Boundary value analysis and equivalence partitioning both are test case design strategies in blackbox testing.
When writing software, destruction can be just as valuable as creation. Because we assume that, all the conditions in one partition behave in the same manner by the software. It contains all basic partition management features, such as resizing partition, extending partition, formatting partition, migrating os to ssd, cloning disk and so on.

It can be of two types forward compatibility testing and backward compatibility testing. Compatibility testing is a nonfunctional testing conducted on the application to evaluate the applications compatibility within different environments.
Of course, there is hope, but it requires a shift in thinking. An advantage of this approach is it reduces the time required for performing testing of a software due to less number of test cases.
