AET Core
a set of system modules that are crucial for the whole system to work. The AET system will not work properly without all core modules configured and running properly.

AET Jobs

AET Maven Plugin
a default client application for the AET system that is used to trigger the execution of the Test Suite.

Amazon Web Services

Apache Karaf
see Karaf.

Artifact

AWS

Collector
a module responsible for gathering data necessary for its further processing (e.g. validation, comparison).

Collection
the first phase of the AET service during which all specified data is collected (e.g. screenshots, page source, js errors). Once they are collected successfully, all collection results are saved in the database.

Comparator
a module responsible for comparing data currently collected to its existing pattern or validating it against a set of defined rules.

Comparison
the second phase of the AET service that performs the operation on the data. In some cases the data collected during the first phase is compared to patterns, in others special validation is performed (e.g. W3C HTML5). The second phase starts before the collection finishes - just the moment when required artifacts are collected and become ready to be compared (e.g. to compare two screenshots system does not have to wait until the source of a page is collected).

Cookie Comparator

Karaf
in fact Apache Karaf is an OSGi container that provides a basic configuration for existing OSGi implementations (e.g. Apache Felix).

Layout Comparator
a comparator responsible for comparing a collected screenshot of page to its pattern.

Login Modifier
a modifier that allows to log in into the application and access secured sites.

Maven
a software project management and comprehension tool. It used as a base for the AET Maven Plugin.

Modifier
a module responsible for converting the target before the data collection process is performed e.g. modifying a requested header, adding a new cookie, hiding a visible element.

MongoDB
an open-source cross-platform document-oriented database that the AET tool makes use of for data storage and management. MongoDB is developed by MongoDB Inc.

Open
A module that is a special operand for the Collect Phase.

OSGi
a modular system and services platform for Java. It is used as an application environment for AET Java components.

pom.xml
a Maven tool configuration file that contains information about the project and configuration details used by Maven to build the project.

Rebasing

Regression testing
this is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system. It is especially useful after changes such as enhancements, patches or configuration changes, have been made.
