Analyzing test run results
Testground test plans emit outputs that you can collect and analyse after the test run concludes.
The outputs structure is as follows:
/|___ <group id> (coming from the composition)| |____ <instance id or index>| |__ run.out| |__ run.err| |__ ...| |__ dht_events.json| |__ heap.out| |__ cpuprofile01.out| |__ cpuprofile02.out| |__ cpuprofile03.out| |____ <instance id or index>| |____ <instance id or index>|___ <group id> (coming from the composition)| |____ <instance id or index>| |____ <instance id or index>
The logic for outputs collection is runner-dependent, e.g.
the
cluster:k8srunner will download from AWS EFS.the
local:dockerrunner will fetch the outputs from the$TESTGROUND_HOMEdirectory.
$ testground collect --runner=local:docker <run-id>$ tar -xzvf <run-id>.tgz
Testground also supports automatic outputs collection after a testplan run completes, with the --collect flag, which instructs the Testground client to download the outputs in the current working directory after the run concludes.
$ testground run single \--plan=network \--testcase=ping-pong \--builder=docker:go \--runner=local:docker \--instances=2 \--collect...>>> Result:INFO finished run with ID: 975b9bc15b3b>>> Result:INFO created file: 975b9bc15b3b.tgz
At the moment Testground doesn't provide any tools for post-processing of outputs. You are free to submit ideas and pull requests and contribute to this feature.
One way to review all messages sent to stdout by test plan instances, is with the following command:
$ cd <run-id>$ find . | grep run.out | xargs awk '{print FILENAME, " >>> ", $0 }'
