A test execution and maintenance system may include an application learner configured to develop knowledge of operations of an application based on one or more learning test. The test execution and maintenance system then may include a test execution and repair manager configured to execute a functional test of the application, detect a failure of the functional test, and repair the functional test based on the knowledge of operations of the application. Responsive to detecting the failure of the functional test, the application learner may optionally perform a re-learning process and update the previously acquired knowledge of operations of the application.

Techniques are described for facilitating transactions involving items and users in various ways. In some situations, item transactions are coordinated by an automated Item Transaction (or 'IT') system provided via one or more computing systems, such that users of the IT system who have available items are matched with other users of the IT system who desire those items. The types of items being involved in transactions via the IT system may vary, and in some situations may include items such as music CDs, video DVDs, computer games, computer software, etc. The operation of the IT system may be enhanced in various ways, including by selecting appropriate users to receive opportunities to sell items available from those users, such as in a manner to balance supply and demand for items, and by notifying the selected users of those opportunities.
