Testing Technique utilized for Positive and Negative Testing

Following strategies are utilized for Positive and negative approval of testing is:

• Boundary Value Analysis
  
• Equivalence Partitioning
  

Boundary Value Analysis:-
This is one of the product testing strategy in which the test cases are intended to include values at the boundary. In input data/information is utilized inside of the boundary value limits, then it is said to be Positive Testing. On the off chance that the data/information is picked outside the boundary esteem limits, then it is said to be Negative Testing.

For instance -
A framework can acknowledge the numbers from 0 to 10 numeric values. Every single other number are invalid values. Under this procedure, boundary values 0 , 10 and - 10 will be tried.

Equivalence Partitioning:- This is a software testing strategy which isolates/breaks the input date into numerous segments .Values from every partition must be tried at least once. Partitions with valid qualities are utilized for Positive Testing. While, partition with invalid qualities are utilized for negative testing.

For instance-
Numeric values Zero to ten can be isolated to two( or three )segment. For our situation we have two parcels - 10 to - 1 and 0 to 10. Test values (5 and - 5) can be taken from every part to test the situations.

Conclusion:-
Testing conveys quality software application and ensures the product is defect free before the product/software is dispatched. For powerful testing, use both - Positive and Negative testing which give enough trust in the nature of the software. Real time users can include any qualities and those should be tried before release.
