NEGATIVE TESTING

SOFTWARE TESTING

The software testing can also be classified as two types of testing one is positive testing and negative testing. Positive testing is the application functions as expected valid data sets. If  an error occurs during positive testing the test fails. In the Negative Testing, the application handles the unexpected  behaviour or invalid input. For example if a user tries to type a wrong data in the field it would display a correct message for incorrect data. The quality of the application improves due to the negative testing.

Negative testing is detecting the possible software crashes in different situations,  such as

  1. Populating required fields
  2. Correspondence between data and field types
  3. Allowed number of characters
  4. Allowed data bounds and limits
  5. Reasonable data

For example  the functioning of a lift in real life. When the people enter and press the floor button automatically the lift is made to move to the required floor. If the number of people exceed in the lift, if a power failure happens during the lift functions – all these cases are included in negative testing. Negative testing is important in the organisation’s perspective because it is the responsibility of every organisation to build  a good quality product to the customer. To achieve this we conduct the negative testing

Negative testing characteristics are:

  • It is carried to point out the faults which can lead to major failures
  • It is performed to find the software weakness and its potential  for exploitation
  • It is conducted to identify how the security breaches can occur.

Negative testing techniques are

  1. Skipping the data and proceeding
  2. Verifying each field type
  3. Verifying numeric data size and boundary tests.

The equivalence partition between negative testing and positive testing is

 

NEGATIVE TESTING
NEGATIVE TESTING

The different types of negative testing situations are:

  1. Filling the values in required fields: The applications behaviour is checked when the test leaves the required fields empty and analyse the response of the application.
  2. Data and field types correspondences: The forms that contain controls can be tested by entering the invalid values to know the proper function of the application.
  3. The number of characters which are allowed: Some fields allow limited characters to be entered. For example: the user name or password field has a specific number of characters
  4. Allowing data bounds and limits: Applications can accept the input value in a certain range of data. For example of negative test: Enter the data in an application that exceeds the data type limit.
  5. Reasonable data values: some applications have reasonable data limit. For example: Enter data limit in the age field in any application.
  6. Web – based testing: some websites have condition to log in or use captcha before opening the first webpage to check whether the application behaves properly.

In positive testing it always proves that the product always meets the requirement specifications.In negative testing the main intention is to test whether the software is not showing the error when it is supposed to show or showing error when it shouldn’t show. Negative testing is a procedure to identify the inputs where system is not designed. The reason behind the negative testing is to check the stability of any software under the influences of various types of incorrect  data set.

    4. Explain the characterstics of Negative testing?
    Negative testing is performed to expose the software weakness and potential for exploitation . It is carried out to showdata corruption or security breaches.

  19. What is negative testing?
    Negative testing is a type of testing where intentionally invalid data is used as an input to check whether the application gives the expected results or error messages.
    Mention the difference between the negative testing and Positive testing.
    Positive testing is a type of testing where testing is done by providing valid data as input and checks whether the application gives the expected results or behaves as expected. It will never give any error.
    The main difference between these two kinds of testing is positive testing uses valid data set and negative testing uses invalid data set. If an error occurs during positive testing the test fails. The data has a limit and is less time consuming. Negative testing can have many options and can be time consuming.
    Positive testing proves that it meets the requirement specifications.
    Negative testing helps to find out the gaps of the application and also find out what kind of data is not giving the expected result, message or not behaving in the expected way.
    In both cases Test designer has to pay attention to the RTM by doing Boundary Value Analysis and by Equivalence Partitioning.
    Boundary Value Analysis, is a testing technique ( with numerical values), where data is out of the boundary or range or limit of the required field. This kind of data is invalid for that field and the testing is called Negative testing. When the data falls under the range or limit, that is called valid data and the testing is called positive testing.
    Equivalence Partitioning, is a software testing technique which divides the input data into many partitions. Values from each partition must be tested at least once. Partitions with valid values are used for Positive Testing. While, partitions with invalid values are used for negative testing.

  20. There are two types of testing one is negative tetsing and the other is positive tetsing .
    Positive testing is the application functions as expected valid data sets.While Negative testing the application handles t
    he unexpected behaviour or invalid input.

    For example: Entering more characters in input text fields when it accepts only 4-8 characters.
    2.Differences between Positive Testing and Negative Testing:
    Positive Testing:
    -Tested to check the application functions as expected.
    -Input is given as the system designed.
    -If errors occur during the positive testing the test fails.
    Negative Testing:
    -Tested to check the functions of application when unexpected behavior occurs.
    -Input is identified for which the system is not designed.
    -The testing ensures that the software can handle the improper behavior of the system.
    3.Advantages of Negative Testing:
    -By performing the negative testing we can ensure that the software can withstand the unexpected behavior of the system also
    ensures the stability and security of the software.
    -Good quality of the product will be provided to the client.
