Software Testing – Software Development Life Cycle


SDLC, or Software Development Life Cycle, is a software engineering term that includes all the software development and deployment processes. It also includes methodologies for designing and developing systems. In software engineering, the SDLC concept underpins many kinds of software development methodologies. The methods referred to are those that help create a framework for developing larger information systems.

Testing is sometimes misinterpreted. People think Testing should be done after the programming of a system or software. Testing should be performed at every level of the development cycle.

Software Testing

The most common types of Testing involved in the development process are:

O Unit Test: This is the first testing level in a software testing cycle. The overall product is divided into small units. Testing of these units individuals is termed Unit Testing.

O System Test: The system level is the upper level of unit testing. Whenever a large system and different programmers code over other units, they are combined, and Testing done over the integrated system is called system testing Integration Test.

O Functional Test: The system is tested for functionality when integrated. To test the function of the system, I termed it functional Testing.

Automated Testing is one of the finest ways to increase the software product’s efficiency, productivity, and accuracy. It simplifies the testing practice by reducing the human effort involved. In this, we create automated test cases and perform those using computerized tools. The automatic testing tool repeats the predefined steps and results more accurately than the manual Testing Eftcrop.

Alpha Testing: Alpha Testing is done after the code is completed to check most of its functionalities before the user starts using it. Sometimes, a select group of users is involved in the Testing. More often, this Testing will be performed in-house/small-scale or by an outside testing firm in close cooperation with the software engineering department.

O Performance Test: This Testing is done when the product is fully developed. Its main objective is to identify the software’s performance according to the customer guidelines.

O Acceptance Test: Testing the software system to confirm the accuracy and efficiency of the product and customer acceptance.

Sometimes, the software is so complex and big that it is practically impossible to test it completely. Before ending software testing, we should keep certain points in mind:

Once the complete software testing is done, the system or software is introduced to the user.
