Bug: arrivalRate and arrivalCount in config are not respected in test run

See original GitHub issue

Versions

Node: v8.1.3 Artillery: v1.6.0-2

Backround

I have a .yml script that has the intent of running a high volume burst of requests. (See example-file.txt) Details:

One phase with duration: 1 and arrivalCount: 340
Eight scenarios, each with one request

Expected result

When the test is run, 340 scenarios should be fired

Actual result

When the test is run, 500 scenarios are fired, final log below:
