Hydra Client

Library used to communicate with hydra-server

Setup

The hydra-client is configured via environment variables:

  • VM_HOSTNAME the name of the individual node that is running the client
  • HYDRA_SERVER the uri of the hydra server
  • HYDRA_HTTPS should https be used to talk to the hydra server
  • HYDRA_CLIENT_TIMEOUT timeout for calls to the hydra server
  • HYDRA_HOST_LIST a comma separated list of nodes that will run tests
  • JOB_NAME name of CI build (exported by jenkins)
  • BUILD_TAG a unique name associated with an individual build (exported by jenkins)
  • HYDRA_CLIENT_ATTEMPTS # of times the client should attempt network requests before giving up

Direct Usage

The easiest way to use hydra-client is via the Gradle plugin, but it can also be directly used inside a Gradle build script:

// the map passed into Configuration.newConfigurationFromEnv is used to override environment variables 
HydraClient client = new HydraClient(Configuration.newConfigurationFromEnv(Collections.emptyMap()))
 
// returns a set of fully qualified test names that should NOT be run
Set<String> testBlacklist = client.getExcludes()
 
// sends test results to the hydra server. TestSuites need to be manually created from test reports, or some other method
client.postTestRuntime(List<TestSuite>)
