TestArchitect has a number of search commands available. You can find an item in the explorer tree, or a text string in files like test modules or action definitions.
Searching items in the TestArchitect explorer tree
A search is conducted within a subtree of a project. The search is restricted to one particular item type (test module, action, data set or interface entity, etc.), and is limited to item names (not item contents or metadata).
Searching item content for text
In addition to item names, you can conduct searches of the text content of test modules, user-defined actions, data sets and interface entities.
