There are two approaches to test the software product i.e. by Positive and Negative testing in software testing. The aim is to discover defects and enhance the software product quality.
Discovering bugs is the fundamental objective for testers, which essentially includes confirming that the product accurately gives an answer for an end-client’s issues. Although, Software testing is a procedure of validating and verifying the software product or application and checks whether it is functioning as expected.
Both the unexpected and expected ways a program performs is secured by two sorts of testing: positive testing and negative testing.
What is Positive Testing?
Positive software testing is a testing procedure to demonstrate that a software product or application under test does what it should do. Positive testing checks how the application acts for the positive arrangement of information.
Any software product framework is exceptionally helpless against wrong information. This appears to be frightening, isn’t obvious? The end clients at some point or another dependably figure out how to redirect from the moral ways, which is hazardous and unsafe. The positive testing causes the managers to rapidly understand and learn these practices to settle issues quickly.
Positive testing additionally encourages the sharing of learning on system architecture since the projects are begun little and tested completely through each and every phase of SDLC.
What is negative testing in software testing?
Software negative testing is a procedure where the framework validated against the void input information. A negative test checks if an application acts as expected with its negative input. The primary goal of this testing is to check whether software application not demonstrating defects when expected to and indicating bugs when shouldn’t. Such testing is to be executed keeping negative perspective and just perform the test cases for just invalid arrangement of information.
Negative testing software development is a testing procedure to recognize the data sources where the framework isn’t planned or un-dealt with contributions by giving distinctive invalid. The principle purpose for negative testing in software is to check the dependability of the software product application against the impacts of various assortment of incorrect validation informational collection.
Assembling Positive and Negative Testing Test Cases:
Positive test cases give a behavioral gauge, so list those first. As these test cases are aggregated, evident negative test cases will normally emerge. For instance, if the application has a sign-on page or gadget, the positive tests guarantee the application handles expected verification data, for example, a client name, a numerical ID or a password. Each of these fields already has a specification with regards to the input expected, for example, letters, numbers and a select arrangement of uncommon characters in addition to adequate string lengths.
The relating negative software testing is to include non-printing characters or strings longer than indicated. These may have different results, for example, a defect is shown, a program crash or the program erroneously signing in the client at any rate. Just a single of those results is most likely adequate and the others are hailed as bugs.
Following procedures are utilized for positive and negative testing in software testing:
Boundary Value Analysis and Equivalence Partitioning
Boundary Value Analysis:
This is one of the software testing methods in which the test cases are intended to incorporate value at the boundary. In any case, the information is utilized inside the boundary value limits, at that point, it is said to be Positive Testing. Whereas if the information is picked outside the boundary value limits, at that point it is said to be Negative Testing.
This is a software product testing system which isolates the info date into many segments. Values from each segment must be tested at any rate once. Partitions with valid values are utilized for Positive Testing. While partitions with invalid values are utilized for negative testing software.
Both positive and negative testing in software testing can be connected all through the software product lifecycle beginning with unit tests. Positive tests incorporate the clear; appear glad in addition to alternate ways that get the client from A to B.
Negative testing incorporates testing the known issues handling abilities of the software product in addition to inputs and activities not represented by the coder. The extent of negative test cases can be fundamentally diminished by utilizing equivalence partition and boundary value analysis.
We, at TestOrigen, provides both positive and negative testing in software testing that are basic to bug finding, which helps us in delivering the highest quality software product.
