1. API data mocking
API mocking is a simulation of real APIs and is performed when the production API is not ready. You may come across a situation where you cannot send an API request to the server because it is not prepared. In such cases, you can mock a chunk of data from the response and eventually, when you make requests the mocked data will be returned.
An API is idempotent when the outcome of a successful request remains unchanged on making the same request frequently.
3. Noisy field
Noisy field refers to the random data whose value changes each time you make a request.
For example, a Timestamp is one such property that returns the time when the request is made. Its value is not fed manually but is automatically recorded therefore, at every call it differs.
Interoperability refers to the situation when the behavior of the data is in its original (native) format when transferred from one platform to other. It reduces the dependency of files by replacing them with optimized code giving the same result.
