What is domain software testing?

Domain Testing is a kind of Functional Testing which tests the application by giving information sources and
assessing its fitting yields. It is a product testing strategy in which the yield of a framework must be tried with
a base number of contributions to such a case to guarantee, that the framework doesn't acknowledge invalid
and out of range input esteems. 

One of the most significant White Box Testing techniques is a space testing. The primary objective of the
Domain testing is to check whether the framework acknowledges the contribution inside the satisfactory range
and conveys the necessary yield. Additionally, it confirms the framework ought not acknowledge the sources of
info, conditions and files outside the predetermined or substantial range.

Practice of Domain Testing

In domain testing, we divide a domain into sub-domains (equivalence classes) and then test using values from
each sub domain. For example, if a website (domain) has been given for testing, we will be dividing the website
into small portions (sub domain) for the ease of testing.

Domain might involve testing of any one input variable or combination of input variables.

Practitioners often study the simplest cases of domain testing less than two other names, "boundary testing"
and "equivalence class analysis."

Boundary testing - Boundary value analysis (BVA) is based on testing at the boundaries between partitions.
We will be testing both the valid and invalid input values in the partition/classes.

Equivalence Class testing - The idea behind this technique is to divide (i.e. to partition) a set of test conditions
into groups or sets that can be considered the same (i.e. the system should handle them equivalently),
hence 'equivalence partitioning.'

That simplified form applies for Domain testing –

Only to tests of input variables

Only when tested at the system level

Only when tested one at a time

Only when tested in a very superficial way
