This package provides an in-memory RethinkDB Server. Designed with testing in mind, the server will allow you to connect your favourite ORM or client library to the RethinkDB Server and run integration tests isolated from each other.
Note about AVA Test Runner
The package was designed to run one server instance (max) at a time. As such it runs one server instance
per test file in AVA (as a result of AVA using forked processes).
This has no negative consequences but it does mean that you should call
RethinkDBServer.start() only once, at the top of an imported file or test file.
Calling it in a helper method may result in either unexpected behaviour or multiple servers running per test file.
The example below uses async/await from ES7. If you wish to use the same syntax,
you should transpile your code using babel-preset-es2017. Alternatively, if you are already
using ES6 then you can convert it to the appropriate Promise syntax.
Available on NPM using: npm install rethinkmem --save-dev or yarn add rethinkmem --dev
Example Using AVA Test Runner:
import test from 'ava';
import r from 'rethinkdbdash';
import { RethinkDBServer } from 'rethinkmem';
test.before(async t => {
await RethinkDBServer.start();
});
test.beforeEach(async t => {
let connectionOptions = await RethinkDBServer.getConnectionParams();
t.context.db = r(connectionOptions);
});
test('something', async t => {
const {db} = t.context;
/// db.table('myTable')...
// Test something amazing?
});
test.after.always(t => {
RethinkDBServer.tearDown(); // This is required to clean up temporary files and processes created.
});
