What Is Negative Testing and Goals of Doing It

The main motto behind conducting tests on a particular software product is to ensure that it will be able to run on all systems and under computing environment of any type. The process of software development has Quality Conformance Testing as an essential part. Throughout the different stages of the developmental process as well as on the final product, various tests are performed before dispatching the item to the end user or the client.



Basically two types of tests are carried out. The first is Positive and the second Negative. While the first caters to tests that verify and validate the product, the second ensures deeper customer satisfaction. Every testing firm has their primary goal edged out in possessing the most optimal product.

Negative Testing is performed to ensure that the application or the software product does not fail to perform in the event of giving the same an unexpected input. Here, the process of validating the system is carried out against the data input that is invalid. This test checks whether an application conforms to its expected behavior even with the negative inputs. It thus ensures the handling of invalid input or a user behavior of unexpected type by a particular application.

Goals of Negative Testing

Negative testing is generally carried out for checking the stability of a particular software application against the influence exerted by different types of data set with incorrect validation. Negative testing usually aims to find the loopholes or the flaws inherent in an application. Thereby, it takes active measures to improve the quality of the same. It results in spotting out the faults that can lead to significant failures or crashes.

This testing is undertaken for exposing the weakness of the software as well as its exploitative potential as well as to showcase the corruption of the data or breach of security. It is usually performed for the purpose of breaking the system and verifying the response of the application in case of unintentional inputs.

Another purpose of this testing is to observe and measure the response of a system to the external problems. It stresses the system beyond the normal limits for which it has been developed besides using the same in an incorrect way. It stresses the system beyond the margins of normal use cases resulting in denial of subsequent service.

Also referred to as Dirty Testing, it is performed to ensure greater satisfaction level of the customer by checking the resistance of the software like if it is carrying out a function that it is not supposed to. For example if particular software opens an application by accepting a password of all letter variables when the requirement is to have at least a number. It tests the software beyond the normal operational limits to be specific it denotes testing a software above its upper specification limit or below the lower one.

It aims to diagnose the expected causes of system failure such as crashes, breach of security, etc as well as to check the validation and rejection of the input. These tests are significant to the companies as they check that the given software is stable enough and is working with respect to its expected functional criterions. These tests are carried out to ensure and verify the proper functioning of the software and thus ensure satisfaction of the customers and clients alike.

The test houses with the help of specialized process to assure the quality of the product carry out different tests to find out maximum flaws or defects while undergoing the testing process. It is done to ensure that the end user or rather the client does not come across any abnormality with respect to the functioning of the same in its computing environment.
