Techopedia Explains Unit Test

A unit test is a quality measurement and evaluation procedure applied in most enterprise software development activities. Generally, a unit test evaluates how software code complies with the overall objective of the software/application/program and how its fitness affects other smaller units. Unit tests may be performed manually – by one or more developer – or through an automated software solution.

When tested, each unit is isolated from the primary program or interface. Unit tests are typically performed after development and prior to publishing, thus facilitating integration and early problem detection. The size or scope of a unit varies by programming language, software application and testing objectives.
