What Are The Software Testing Methods?

What Are The Software Testing Methods?

Software Testing Methods In Software Engineering

There is a three types of software testing methodologies or QA methodologies or testing methodologies in software testing:

                 1. White Box Testing

                 2. Black Box Testing

                 3. Grey Box Testing

1. White Box Testing In Software Testing

  • White box testing is done by coder because code knowledge is required.
  • It is also called as code level testing/unit testing/clear box testing.
  • In white box testing whenever coder complete his code writing, he checks or compile code then if any bug found coder have to solve it.
  • Coder cannot send code to test without doing white box testing.
  • Coder check or test mostly positive scenarios only.
  • White box testing has purpose to test correctness and completeness of the program. 

  

 2. Black Box Testing In Software Testing

  • Black box testing is known system and function testing.
  • This testing is done by tester.
  • Overall functionality get checked in this type of testing.
  • Tester check internal functionality depend upon external functionality.
  • Example: Tester check whenever data is sign module got entered and users press sign up button, this button is process to store entered data. Tester check whether the data is stored correctly or not. So here internal functionality is storing of data and external functionality is filling up data in fields and submit buttons process.

 

Tester test the positive and negative scenarios.

 

Positive scenario means:

If suppose we have mobile number field with 10 digit functionality then as a tester we will check field functionality by entering 10 digit number whether it works or not.

 

Negative scenario means:

If suppose we have mobile number field with 10 digit functionality then as a tester if we check with 9 digits or less as it should not accept or more than 10 digits.

 

3. Grey Box Testing In Software Testing

  • Grey box testing is a combination of both white box and black box.
  • To do grey box testing, tester need programming knowledge
  • The role of grey box tester is whenever final software is handed over to tester then tester check its functionality and if any fault occur in the output of function then tester does not revert system back to developer, Instead of that tester himself solve or make changes in the code. So knowledge of coding is required.
