The process of Software Testing includes executing an application or a program to find out the software bugs. It evaluates software items to validate and verify whether all the software requirements are aptly implemented or not. Software Testing ensures that the software meets the technical and business needs, works as per the requirements, and can be made live with the specified characteristics.
The process of Software Verification ensures that the software product verifies the conditions that were planned to be implemented while starting the software. It includes inspections, reviews, walk throughs, and meetings to assess the plans, specifications, codes, documents, and requirements. In simple words, it makes sure whether the software is going the way it is supposed to be.
The process of Software Validation is done at the end of the development phase. It is performed after the software product is produced against the decided criteria and it also makes sure that the software appropriately integrates with the organization’s goals and user environment.
Basics of Software Testing
It is a technique that treats the software like a black box and examines specified functions and behaviors without any knowledge about the internal implementation of the system. The tester entirely focuses on the output and not on ‘how’ the units and functions are implemented. It is also known as Functional Testing.
It is a technique that treats the software like a white box and test internal structures or working of the software product. Under this type of testing technique the tester needs the knowledge of how the software is used and how it will work at the user’s end. It is also known as Structural Testing and Glass Box Testing.
Types of Testing
Unit Testing: It is the testing of individual units of source code along with associated control data to verify if they are suitable for use or not.
Integration Testing: Under this type of testing the individual software modules are combined to form a group of components in order to produce the output.
Functional Testing: This type of testing verifies the specific function or action of the code. It also ensures if the specific functionality needed by the system requirements, work or not.
System Testing: Under this testing the software is put in different environments, like on various Operating Systems, and checked if it works well with them too.
Performance Testing: It is executed to find out if a system or a sub-system is performing well in terms of stability or responsiveness when put under a specific workload.
Beta Testing: This testing is done by the end users and usually done by an outside development team and known as the beta version of the software product.
Verification, validation and final implementation of the software are needed in every work environment and this can only be done by a professional tester. Expertise can be gained in software testing through a formal training and this can open a wide range of opportunities for testers.
