- In science, an experiment performed to verify the presence, the quality or the quantity of determined characteristics or elements in a specimen.
- Similarly, in software engineering, an experiment to determine some characteristic of a software system. See software testing.
Testing is the process of checking whether something is true or false, whether it is valid, or whether it is functional.
A test compares an expectation about something with an observation of it. The expectation must exist (in the mind of the tester, on paper, in discussion, etc.) before the observation is taken. If no expected values exist, it cannot be a test, but merely an observation.
In Software development
Alpha Test
In software development, testing is usually required before release to the general public. In-house developers often test the software in what is known as 'alpha' testing which is often performed under a debugger or with hardware-assisted debugging to catch bugs quickly. It can then be handed over to quality assurance staff for additional testing in an environment simular to how it was intended to be used.
This is often known as the second stage of alpha testing.
Beta Test
Following that, limited public tests known as beta-versions are often released to groups of people so that further testing can ensure the product has few faults or bugs.
Gamma Test
There are companies that introduced the so-called gamma tests, which means feature-completed, but the software did not run through all the inhouse quality checks
In Science
Test is the 4th stage of the scientific method.
In Manufacturing
Test is part of Quality Assurance. Typically, measurements are taken, and test results are recorded. To reduce the cost of testing, sampling is typically used, in a statistical test.
See also crash test, Statistical hypothesis testing, Likelihood-ratio test.
Test (student assessment). A tool or technique intended to measure student's performance, knowledge or skills.
Geography. The river Test is a river in Hampshire, England.
Test is also the professional wrestling name of Andrew Martin. His entry can be found at that link.
A better place to "test" out new Misplaced Pages code is in the Misplaced Pages sandbox.
