Software testing ensures that features work, detects bugs, and checks for fixes before release. Dynamic testing evaluates software as it is being used in different environments, while static testing finds syntax errors and coding problems. Beta testers are often used for further dynamic testing and report any issues.
Software includes operating systems and programs designed to run on one or more of them. Software testing is a process of examining and using software during and after development, but before release, to verify that features work, detect bugs, check for bug fixes, and make sure it works well for users. Dynamic testing, also called dynamic analysis, is the process of evaluating software as it is being used. It is in contrast to static testing, which is the analysis of a program that is done without running the program. Other types of tests include response time tests and backtesting.
Static testing and dynamic testing together are two of the main types of software testing that are undertaken and balance each other out in certain ways. On the one hand, the static test finds syntax errors and other coding problems and covers the entire program. On the other hand, dynamic testing of a large and complex program may often not cover the entire program because not all possible scenarios can be imagined or created in the time spent on testing.
Dynamic testing analyzes the software program in different operating environments. This includes different computer brands and other hardware differences, possibly including multiple monitors, different operating systems, and different sets of software applications coexisting on the machine. Also, testers may have external modules or plug-ins that they use in relation to the software under test which increases the differentiation of test environments in dynamic testing.
Dynamic testing within a software development company is likely to follow the guidelines and protocols set forth by the Institute of Electrical and Electronics Engineers (IEEE) for software testing and the test plan that the company has developed in compliance with these. Beta testers external to a company are often used for further testing and usually these testers are fully involved in dynamic testing. Usually an attempt is made to have a diverse group of beta testers in terms of hardware, operating systems, and program usage, as the case may be. Beta testers, who may have a non-disclosure agreement with the company, may have a protocol to follow or be asked to use the software in the way they would normally use it, or they may be a part of either. There is typically a formal reporting system for beta testers to report crashes, suspected bugs, features not working as described, or any other unusual, unexpected, or inconvenient aspect of working with the software.
