Analyzing test run results
Testground outputs structure
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>
How to collect Testground outputs
The logic for outputs
collection is runner-dependent, e.g.
the
cluster:k8s
runner will download from AWS EFS.the
local:docker
runner will fetch the outputs from the$TESTGROUND_HOME
directory.
$ 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
Processing the Testground outputs
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 }'
