In computing, software engineering and software testing a test oracle, or just oracle, is a mechanism for determining whether a test has passed or failed. The use of oracles involves comparing the output(s) of the system under test, for a given test-case input, to the output(s) that the oracle determines that product should have. The term "test oracle" was first introduced in a paper by William E. Howden. Additional work on different kinds of oracles was explored by Elaine Weyuker.

Methods and apparatus for enterprise application integration
InactiveUS7058637B2Data processing applicationsWebsite content managementScripting languageEnterprise application integration
A method for enterprise application integration that uses “connectors” that can be instantiated via downloading (e.g., using Java® or other such technologies) to provide interfaces to respective disparate database systems. The databases systems may comprise any variety of now or heretofore known systems, e.g. SAP, Oracle, and so forth. The connectors can, for example, translate between a native language (or API) of the respective database systems and an internal language / protocol of the enterprise application integration system. To this end, the connectors can utilize a scripting language to access the respective database systems. Data retrieved from the database systems can be stored in a central data store in the form of RDF triplets, from which directed graphs can be generated for to generate presentations consolidated from the multiple database systems.

A configuration system for an application having a plurality of application components is described. The configuration system includes a configuration oracle / initiator that repeatedly asserts a desired state to the application components to operate in that desired state. The desired state is a predetermined state. The configuration oracle only asserts the desired state to the application components and does not control the manner in which each of the application components moves to the desired state. The configuration system also includes a configuration engine in each of the application components that causes the corresponding application components to move to the desired state upon receiving the state assertion of the desired state unless the configuration engine determines that the corresponding application component is already in the desired state. A method of configuring an application having a large number of application components is also described.

A decentralized price discovery platform, with bi-directional quotes, is a market for market makers to place quotes attesting to the value of a condition occurring outside of a blockchain, and insuring the value of the condition against movement with a backing value of blockchain tokens. An aggregate consensus value is computed based on the aggregate of all active bi-directional quotes to yield an oracle value that can be used by other participants in the blockchain network for decentralized applications relying on the value of the condition occurring outside the blockchain. The aggregate consensus value is further used to adjust estimated premiums on active bi-directional quotes to fair values such that the aggregate consensus value should converge to the true value of the condition occurring outside the blockchain. Traders fill di-directional quotes to yield consensus trades, providing insurance against price movement, and causing the aggregate consensus value to converge on a true value.
