Software Testing

Software Testing :

  • It is a method to check whether the actual software product matches expected requirements and to ensure that the software product is Defect free. 
  • It involves execution of software/system components using manual or automated tools to evaluate one or more properties of interest.
  • The purpose of software testing is to identify errors, gaps or missing requirements in contrast to actual requirements.
  • Some prefer saying Software testing definition as a White Box and Black Box Testing. In simple terms, Software Testing means the Verification of Application Under Test (AUT).
  • It is an evaluation of the software against requirements gathered from users and system specifications. Testing is conducted at the phase level in software development life cycle or at module level in program code. Software testing comprises Validation and Verification.
  • This Software Testing course introduces testing software to the audience and justifies the importance of software testing.

Testing  Objectives:

  1. Finding defects which may get created by the programmer while developing the software.
  2. Gaining confidence in and providing information about the level of quality.
  3. To prevent defects.
  4. To make sure that the end result meets the business and user requirements.
  5. The objective of the testing is finding as many software defects as possible
  6. Ensure that the software under test is bug free before release
