CouchDB in-memory implementation

Question

Is there a mock backend for CouchDB, i.e. same REST interface and semantics but purely in-memory? We have a testsuite that runs each test on a pristine database every time (to be reproducible), but running against real database could be faster.

Answer 1

Do you mean running against a mock database?

I do not think there is something right out of the box. Two ideas:

1. CouchDB on a memory filesystem. Set up a ramdisk, or tmpfs mount, and configure the CouchDB database_dir and view_index_dir to point to there.
2. PouchDB is porting CouchDB to the browser IndexedDB standard. You did not say which language and environment you are using, but if you can run Node.js, this might be worth looking into. PouchDB has good momentum and I think it will be running in Node.js soon (perhaps through jsdom or some other library. Note, this does not get you the full solution; but you have expanded your question to "are there in-memory IndexedDB implementations for Node.js" for which the answer is either "yes" or "soon," given its adoption trajectory.
