Glossary

Attribute

Operation (normally, one-argument), the result of which is stored in its argument and cannot be changed any more.

List

Data structure whose elements are indexed by their position in the list.

Method

Function that will be called for an operation for arguments of the specified type.

Operation

GAP function for which several methods may be available (the particular method that will be used depends on the type of the arguments).

Property

Boolean-valued attribute

Record

Data structure which is a collection of components, each having a unique name, which is an identifier that distinguishes this component, and a value, which is an object of arbitrary type.

Regression testing

Testing based on rerunning previously completed tests to check that new changes do not impact their correctness or worsen their performance.
