Topology, testbed, and device abtraction.

Feature categories for maintaining tests:

• Topology, testbed, and device abstraction

Maintain tests
Topology, testbed, and device abstraction
Graphical Topology Editor	Create and edit graphical topologies within iTest using new industry standard TBML files. Leverage a topology to start sessions and communicate iTest setup requirements with others. Device properties are conveniently aggregated and editable in properties view. Test reports include image snapshot of topology diagram.
Testbed definitions	Define testbeds as a set of named devices in separate testbed documents, so that test cases can port easily between different testbeds-even when the testbeds contain different versions or variants of the devices.  定義測試平台作為一套名為試驗台設備在單獨的文件，使testcase可以很容易在不同的測試平台端口，即使在測試平台包含了不同的版本或變種的設備。
Session profiles	Allow sessions to be started instantly and dragged and dropped into any test case. When devices or their properties change, the powerful abstraction techniques provided by iTest allow users to modify only the one session profile, rather than every test case
Scriptless parsing	Automatically convert raw text, unstructured data, and structured data (IP addresses, MAC addresses, timestamps, integers, real numbers, and so on) into easily manageable variables (tokens).
Scriptless analysis definitions	Declare expected behavior easily by selecting among a set of rules and arguments that are customized to the specific context, and then editing and/or combining the rules to achieve precisely the desired analysis.
Web page mapping	Convert a Web page into a set of easily recognized targets (links, buttons, text fields, tables) for easy test case maintenance and abstraction. When targets change on the page, users need to modify only the one map, rather than every test case.
Named variables, queries, and parameters	Specify and name critical variables/tokens (words, whitespace, numbers, IP addresses, timestamps) to enable test case portability across product variants.
Automatic Response Mapping (ARM)	ARM makes the generation of response maps easier by leveraging the gray boxes created with IRP to quickly create response maps. Query-based analysis rules constructed with IRP can be abstracted with the creation of a corresponding response map.
Response Map Wizard	Accelerates response map creation for a broad class of responses. When responses change, users need to modify only the one map, rather than every test case. This allows tests to be easily maintained for fully automated regression testing across releases.
