Software testing is an essential aspect of the software development lifecycle. It ensures the smooth delivery of a product. A software should pass the minimum required quality assurance barrier for a consumer to have hassle-free usage.The intent behind software testing is:1.To find whether the developed software is as per requirements or not2.To ensure that the product is error-freeWhy Software Testing is NecessaryIn April 2015, a software glitch caused Bloomberg terminal, London, to crash. It had an enormous impact affecting more than 300,000 traders in financial markets. There are many such cases of the colossal loss of lives and property due to minor software glitches. Hence, software testing is crucial.Types of Software Testing1. Functional TestingIt is used to test the features/functionality of a system or software. It ensures that the requirements are adequately satisfied by the application.Functional testing types include:
Unit Testing
Unit Testing involves testing of individual software components or modules. It is typically executed by the programmer and not by testers.
Integration Testing
Integration testing is performed to verify the combined functionality of an application through the assessment of integrated modules. It includes code modules, individual applications, client and server applications on a network, and more.
System Testing
In this type of testing, the entire system is tested as per the requirements. It is a black-box type of testing based on overall requirement specifications. It covers all the combined parts of a system.
Sanity Testing
Sanity testing is done to assess if new software is performing well enough to accept it for a significant testing effort. If an application crashes during its first use, then the system is deemed to be unstable enough for further testing.
Smoke Testing
Smoke testing detects the presence of any bug or issue that would hinder the testing process. If testers find any critical functionality being broken down at the initial stage itself, then the testing team can reject the version.
Graphical User Interface (GUI) Testing
GUI testing helps in validating the user interface, and user experience is developed as per the client requirements or not.
Acceptance Testing
The client performs acceptance testing. It helps in verifying whether the end-to-end flow of the system is as per the specified requirements or not. This process is the last step of the testing process, after which the software is moved to production. 2.Non-Functional TestingNon-Functional testing is used to verify that various attributes of a system work appropriately. It includes system performance, execution speed, load on the server, the robustness of the system, and more. Non-Functional testing types include:
Performance Testing
Performance testing aids in assessing the system’s performance metrics and requirements.
Load Testing
Its critical objective is to test load capacity or maximum workload a system can handle without degrading its performance. Some standard load testing tools are JMeter, LoadRunner, WebLoad, Silk performer, and more.
Stress Testing
Stress testing assesses the situation when a system is stressed beyond its specifications. It assists in checking under the severe circumstance, how and when it fails.
Volume Testing
In volume testing, the software or application undergoes a considerable amount of data. It helps analyze the behavior and response time of the app when it comes across such large data sets.
Security Testing
Security testing is executed to analyze the security of software or application or website from internal and external threats. It includes penetration testings and other techniques to see how much the system is secure from hacking attacks.
Compatibility Testing
This type of testing ensures the compatibility aspects of the software. It tests whether the software can be executed on a different configuration, databases, browsers, as well as their versions.
Recovery Testing
Recovery testing helps determine if the system can continue the operation after a disaster.
Usability Testing
The user-friendliness of a system is tested through usability testing. It also checks if a new user can understand the application easily or not.Software testers are a critical aspect of project development. Hence, they are in huge demand.
