Loop Testing is a kind of software testing that checks the accuracy of the loop constructions. There is one component of Control Structure Testing for path testing, validation testing for wrong data, and condition testing for different scenarios.
Loop testing is an example of white-box testing. This technic is used to test software loops and it is one type of control structure testing.
We have performed a loop test because of the following reasons:
It must be tested with three separate stages within the testing loop −
Here different 4 types of loop tests −
Below explain these 4 types of loop tests in detail.
Testing performed by one simple loop is known as Simple loop testing. In simple loops normally added “for”, “while” or “do-while” loops in which we have given condition and loop run and terminates according to true and false condition result. This type of testing is performed basically to test the different conditions of the loop. Below is the syntax of the simple while loop.Example:
Below are the described steps of how a simple loop is tested −
Testing performed in a nested loop means loops under the loop is known as Nested loop testing. This means a Nested loop is the finite number of loops inside another loop. It may be for, a while, or a do-while loop. Below is the syntax of the nested loop.Example:
You must perform the following steps to create a nested loop −
Testing done using the concatenated loop is known as Concatenated loop testing. It is performed on the concatenated loops. In a concatenated loop, one loop is after another loop. It is one type of loop chain. The difference between nested and concatenated is that in the nested loop one loop is inside the other loop and for Concatenated loop is one loop after the other loop.
In the concatenated loops, if two loops are tested as independent of each other then they both are tested using simple loops or else test them as nested loops.
If here one loop counter is used as a starting value for other loops then we cannot consider it as independent loops.Example:
The unstructured loop is the combination of nested loops and concatenated loops. It is basically a collection of loops that are in no order.
In unstructured loops, the construction of the loops is must be restructured for representing the use of structured programming techniques.Example:
Below are the advantages:
