Editing unit tests

Unit tests can be find from /backend/test folder. There are four unit test files: tests.js, userTests.js, postTests.js and searchTests.js. tests.js contains some preliminary preparations for all tests and has order witch tests should be run. Other files have unit tests related to their own routers and controllers. Unit tests have been written with Mocha test framework and Chai assertion library. Familiarize your self with those libraries before editing tests.

Python scripts

Python scripts in the test folder are used for data generation. Those scripts generates 101 users and 100 posts. Generated data is used in unit tests. If more advanced data is needed for testing those scripts could be modified.
