Overview

Package testbed allows to easily set up a test that requires running the agent and a load generator, measure and define resource consumption expectations for the agent, fail tests automatically when expectations are exceeded.

Each test case requires a agent configuration file and (optionally) load generator spec file. Test cases are defined as regular Go tests.

Agent and load generator must be pre-built and their paths must be specified in test bed config file. RUN_TESTBED env variable must be defined for tests to run.
