Explain Positive Testing And Negative Testing With Example?

Positive Testing: - When tester test the application from positive point of mind than it is known as positive testing.

Testing the application with valid input and data is known as positive testing.

Positive testing: - A test which is designed to check that application is correctly working. Here the aim of tester is to pass affecting application, sometimes it is obviously called as clean testing, and that is “test to pass”.

Negative Testing: - When tester test the application from negative point of mind than it is known as negative testing.

Testing the application always with invalid input and data is known as negative testing.

Example of positive testing is given below:

Considering example length of password defined in requirements is 6 to 20 characters, and whenever we check the application by giving alphanumeric characters on password field “between” 6 to 20 characters than it is positive testing, because we test the application with valid data/ input.

Example of negative testing is given below:

Considering example as we know phone no field does not accept the alphabets and special characters it obviously accepts numbers, but if we type alphabets and special characters on phone number field to check it accepts the alphabets and special characters or not than it is negative testing.

Conclusion: -

At end we conclude that tester has to perform both these testing simultaneously.
