Highlights

Supervision trees have been introduced for users, coordinators, and throttles, that give better load-balancing, as well as introspection using observability tools.

What's Changed

• Controller/Return a more explicit running status from by @NelsonVides in #171
• Add telemetry event for a coordinator trigger by @NelsonVides in #177
• Supervision trees and test coverage by @NelsonVides in #178
• Ensure change_rate_gradually runs for long enough to the test to succeed by @NelsonVides in #179
• Throttles/rework run and sending logic by @NelsonVides in #180
• Users supervision tree by @NelsonVides in #175

Potential incompatibilities:

Since #171 the controller get_status/0 callback returns a map with named values, for more explicit information. If the previous return value was being pattern-matched in your code, this needs to be updated.

Highlights

The load-testing framework for massively parallel testing, more generic than ever!

What started as a load-testing tool for our internal use-cases, has grown over years of experience and uncountable use-cases to be a generic tool for load testing, completely flexible to fit any use-case.

This version leaves the specific decisions of your environment to you, exposing comprehensive instrumentation for you to plug your own metrics and logging backends of choice; a clearly documented interface to plug your preferred APIs; and language agnostic, supporting now scenario distribution in a cluster by distributing BEAM bytecode directly and allowing you to provide your own parser for environment variables, so that you can run your scenarios in any language that runs on top of the BEAM.

Where all these choices were enforced, now amoc lets you choose as it fits. For a drop-in replacement of the old amoc, where Graphite, REST, and Erlang have already been chosen, see amoc-arsenal.
