OData (Open Data Protocol)
OData means Open Data Protocol. Odata is a uniform procedure built over existing HTTP and REST protocols in support of the four basic functions of persistent storage CRUD -Create, Read, Update, and Delete, to create and consume data APIs. RESTful API’s are build and consumed with the help of best practices recognized by OData. Odata is used to find out changes for recognizing functions for reusable actions and transfer batch requirements. OData provides ability for addition to complete the custom needs of RESTful APIs. It is based on REST protocol for query and updating of data. Odata is built on uniform technology such as HTTP, Atom/XML, and JSON. It supports to center on the logic of the business, while constructing RESTful APIs.

In the first case, API is a broad, not well-defined term and so is API testing.
We will use a different terminology and talk about system tests for OData services. Systems tests are black box tests that execute and validate a function belonging to a software product addressing all required components and their integration. That is, no component is replaced by a test-double – the complete stack is tested.
In contrast, integration tests and component tests address single components or the integration of components while isolating certain other components. The application logic exposed by an OData service should be covered by such tests (and unit tests, of course).
OData system tests require an OData client. Your test must address the OData service like any other “external” consumer. This does not imply that the OData client has to reside outside the system. The test just needs to call operations of the OData service as if they originated outside the system. We will an example below.
Having an OData client is one thing. For proper testing, it must be embedded in a test framework that manages test cases, controls test execution, monitoring and test result reporting.
