Thus it will be necessary to follow up any positive result with a more reliable test to obtain a more accurate assessment as to whether cancer is present.
What is Performance Testing? To test the application we need to give some input and check if getting result as per mentioned in the requirements or not. Testing of application can be carried out in two different ways, Positive testing and Negative testing. In this testing tester always check for only valid set of values and check if a application behaves as expected with its expected inputs.
Positive Testing always tries to prove that a given product and project always meets the requirements and specifications. Under Positive testing is test the normal day to day life scenarios and check the expected behavior of application.
Example of Positive testing: Consider a scenario where you want to test an application which contains a simple textbox to enter age and requirements say that it should take only integers values.
So here provide only positive integer values to check whether it is working as expected or not is the Positive Testing. Most of the applications developers are implement Positive scenarios where testers get less defects count around positive testing. Negative testing is a testing process to identify the inputs where system is not designed or un-handled inputs by providing different invalid.
The main reason behind Negative testing is to check the stability of the software application against the influences of different variety of incorrect validation data set. Example of Negative Testing Consider a same above age textbox example which should accept only integers values.
The Negative testing helps to improve the testing coverage of your software application under test. Both positive and negative testing approaches are equally important for making your application more reliable and stable.
If the requirement is saying that password text field should accepts 6 — 20 characters and only alphanumeric characters. Password textbox should accept 6 characters Password textbox should upto 20 characters Password textbox should accepts any value in between chars length.
Password textbox should not accept less than 6 characters Password textbox should not exceeds more than 20 characters Password textbox should not accept special characters Conclusion: Keep in mind that both positive and negative testing is equally important for effective testing which help to improve quality of software.
End users can enter any input values, such real life scenarios can be tested before moving software live. Main aim means purpose of Positive and Negative Testing is to prove that the application works as per the requirements and specifications.

Adding Positive and Negative Numbers. Once you understand the basics of positive and negative numbers, you can start to add them together. Sometimes this seems tricky, because there are lots of rules to remember and follow.
We’ll go through them slowly so that you understand. Learn about the rules of positive and negative integers.
Improve your math skills with tips for addition, subtraction, multiplication, and division. Using a number line showing both sides of zero is very helpful to help develop the understanding of working with positive and negative numbers/integers.
It's easier to keep track of the negative numbers if you enclose them in brackets. The positive and negative predictive values (PPV and NPV respectively) are the proportions of positive and negative results in statistics and diagnostic tests that are true positive and true negative results, respectively.
The Negative testing helps to improve the testing coverage of your software application under test. Both positive and negative testing approaches are equally important for .
