const db = new Database();
(async function() {
  const now = Date.now();
  try {

    const result = await cursor.next();
    // ...
  } catch (err) {
    // ...
  }

var arangojs = require("arangojs");
var db = new arangojs.Database();
var now = Date.now();
db.query({
  query: "RETURN @value",
  bindVars: { value: now }
})
  .then(function(cursor) {
    return cursor.next().then(function(result) {
      // ...

Testing

Run the tests using the yarn test or npm test commands:

yarn test
# - or -
npm test

By default the tests will be run against a server listening on http://localhost:8529 (using username root with no password). To override this, you can set the environment variable TEST_ARANGODB_URL to something different:

TEST_ARANGODB_URL=http://myserver.local:8530 yarn test
# - or -
TEST_ARANGODB_URL=http://myserver.local:8530 npm test

For development arangojs tracks the development build of ArangoDB. This means tests may reflect behavior that does not match any existing public release of ArangoDB.

To run tests for a specific release of ArangoDB other than the latest development build, use the environment variable ARANGO_VERSION, e.g. for 3.3:

ARANGO_VERSION=30300 yarn test
# - or -
ARANGO_VERSION=30300 npm test

The value follows the same format as the arangoVersion config option, i.e. XYYZZ where X is the major version, YY is the two digit minor version and ZZ is the two digit patch version (both zero filled to two digits).

Any incompatible tests will appear as skipped (not failed) in the test result.

To run the resilience/failover tests you need to set the environment variables RESILIENCE_ARANGO_BASEPATH (to use a local build of ArangoDB) or RESILIENCE_DOCKER_IMAGE (to use a docker image by name):

RESILIENCE_ARANGO_BASEPATH=../arangodb yarn test
# - or -
RESILIENCE_ARANGO_BASEPATH=../arangodb npm test

This runs only the resilience/failover tests, without running any other tests.

Note that these tests are generally a lot slower than the regular test suite because they involve shutting down and restarting individual ArangoDB server instances.
