Software Testing


To stay ahead of competitions, agile businesses should be able to adopt new technologies quickly, whether its operating systems, servers or software. Though changes often introduced in web application development, the application testing should enable the businesses to quickly adopt the new technologies, eliminating the risk associated with it.

Application testing is an investigation / set of activities conducted on software to find errors & to provide information about the quality of the product or services. Its nothing but operating the software under controlled conditions like (1) verifies whether it behaves “as specified” (2) detect errors (3) validate whether the things specified is what actually the users want. Software testing can be stated as a process of validating & verifying the Software / Application / Product, whether it:

  1. Meets the business & technical requirements of design and development
  2. Works as efficient
  3. Executes with the same characteristics

Types of Software Testing:

  • Unit Test – It’s the first level of testing in the cycle of software testing process. The overall product or service is divided into small units and testing these units individually is called as unit testing.
  • System Test – Upper level of unit testing is done, when there is large system or different programmers coding different units. It is combined and testing is done over the combined system.
  • Functional Test – When the system is incorporated, testing is done on its functionality. Testing the function of the system is termed as functional testing.
  • Automated Testing – Automated testing increases the efficiency, productivity and accuracy of the software product. This method simplifies the testing practice and reduces the human effort i.e. it create automated test cases and perform those using automated tools.
  • Alpha Testing – It is done once the code is completed & most of its functionalities are ready for check, before the actual user start using it. This testing is often performed in-house/small scale.
  • Performance Test – It is performed once the product is fully developed. This test identifies the performance of the software with regards to the customer guidelines.
  • Acceptance Test – Testing the software with the intent of confirming accurateness, efficiency of the product and customer acceptance.

Things to Consider Before the End of Software Testing:

  1. Testing guidelines should be met
  2. Test cases should cover every aspect of the software.
  3. Minimum of bugs in the software
  4. All the defined test cases should be run at least once.
