Job Replay

In order to reproduce a given job using the same data, one can use the --replay option for the run command, informing the hash id from the original job to be replayed. The hash id can be partial, as long as the provided part corresponds to the initial characters of the original job id and it is also unique enough. Or, instead of the job id, you can use the string latest and avocado will replay the latest job executed.

Let’s see an example. First, running a simple job with two test references:

$ avocado run /bin/true /bin/false
JOB ID     : 825b860b0c2f6ec48953c638432e3e323f8d7cad
JOB LOG    : $HOME/avocado/job-results/job-2016-01-11T16.14-825b860/job.log
 (1/2) /bin/true: PASS (0.01 s)
 (2/2) /bin/false: FAIL (0.01 s)
RESULTS    : PASS 1 | ERROR 0 | FAIL 1 | SKIP 0 | WARN 0 | INTERRUPT 0
JOB TIME   : 0.12 s
JOB HTML   : $HOME/avocado/job-results/job-2016-01-11T16.14-825b860/html/results.html

Now we can replay the job by running:

$ avocado run --replay 825b86
JOB ID     : 55a0d10132c02b8cc87deb2b480bfd8abbd956c3
SRC JOB ID : 825b860b0c2f6ec48953c638432e3e323f8d7cad
JOB LOG    : $HOME/avocado/job-results/job-2016-01-11T16.18-55a0d10/job.log
 (1/2) /bin/true: PASS (0.01 s)
 (2/2) /bin/false: FAIL (0.01 s)
RESULTS    : PASS 1 | ERROR 0 | FAIL 1 | SKIP 0 | WARN 0 | INTERRUPT 0
JOB TIME   : 0.11 s
JOB HTML   : $HOME/avocado/job-results/job-2016-01-11T16.18-55a0d10/html/results.html

The replay feature will retrieve the original test references, the variants and the configuration. Let’s see another example, now using a mux YAML file:

$ avocado run /bin/true /bin/false --mux-yaml mux-environment.yaml
JOB ID     : bd6aa3b852d4290637b5e771b371537541043d1d
JOB LOG    : $HOME/avocado/job-results/job-2016-01-11T21.56-bd6aa3b/job.log
 (1/4) /bin/true;first-c49a: PASS (0.01 s)
 (2/4) /bin/true;second-f05f: PASS (0.01 s)
 (3/4) /bin/false;first-c49a: FAIL (0.04 s)
 (4/4) /bin/false;second-f05f: FAIL (0.04 s)
RESULTS    : PASS 2 | ERROR 0 | FAIL 2 | SKIP 0 | WARN 0 | INTERRUPT 0
JOB TIME   : 0.19 s
JOB HTML   : $HOME/avocado/job-results/job-2016-01-11T21.56-bd6aa3b/html/results.html

We can replay the job as is, using $ avocado run --replay latest, or replay the job ignoring the variants, as below:

$ avocado run --replay bd6aa3b --replay-ignore variants
Ignoring variants from source job with --replay-ignore.
JOB ID     : d5a46186ee0fb4645e3f7758814003d76c980bf9
SRC JOB ID : bd6aa3b852d4290637b5e771b371537541043d1d
JOB LOG    : $HOME/avocado/job-results/job-2016-01-11T22.01-d5a4618/job.log
 (1/2) /bin/true: PASS (0.01 s)
 (2/2) /bin/false: FAIL (0.01 s)
RESULTS    : PASS 1 | ERROR 0 | FAIL 1 | SKIP 0 | WARN 0 | INTERRUPT 0
JOB TIME   : 0.12 s
JOB HTML   : $HOME/avocado/job-results/job-2016-01-11T22.01-d5a4618/html/results.html

Also, it is possible to replay only the variants that faced a given result, using the option --replay-test-status. See the example below:

$ avocado run --replay bd6aa3b --replay-test-status FAIL
JOB ID     : 2e1dc41af6ed64895f3bb45e3820c5cc62a9b6eb
SRC JOB ID : bd6aa3b852d4290637b5e771b371537541043d1d
JOB LOG    : $HOME/avocado/job-results/job-2016-01-12T00.38-2e1dc41/job.log
 (1/4) /bin/true;first-c49a: SKIP
 (2/4) /bin/true;second-f05f: SKIP
 (3/4) /bin/false;first-c49a: FAIL (0.03 s)
 (4/4) /bin/false;second-f05f: FAIL (0.04 s)
RESULTS    : PASS 0 | ERROR 0 | FAIL 24 | SKIP 24 | WARN 0 | INTERRUPT 0
JOB TIME   : 0.29 s
JOB HTML   : $HOME/avocado/job-results/job-2016-01-12T00.38-2e1dc41/html/results.html

Of which one special example is --replay-test-status INTERRUPTED or simply --replay-resume, which SKIPs the executed tests and only executes the ones which were CANCELED or not executed after a CANCELED test. This feature should work even on hard interruptions like system crash.

When replaying jobs that were executed with the --failfast on option, you can disable the failfast option using --failfast off in the replay job.

To be able to replay a job, avocado records the job data in the same job results directory, inside a subdirectory named replay. If a given job has a non-default path to record the logs, when the replay time comes, we need to inform where the logs are. See the example below:

$ avocado run /bin/true --job-results-dir /tmp/avocado_results/
JOB ID     : f1b1c870ad892eac6064a5332f1bbe38cda0aaf3
JOB LOG    : /tmp/avocado_results/job-2016-01-11T22.10-f1b1c87/job.log
 (1/1) /bin/true: PASS (0.01 s)
RESULTS    : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0
JOB TIME   : 0.11 s
JOB HTML   : /tmp/avocado_results/job-2016-01-11T22.10-f1b1c87/html/results.html

Trying to replay the job, it fails:

$ avocado run --replay f1b1
can't find job results directory in '$HOME/avocado/job-results'

In this case, we have to inform where the job results directory is located:

$ avocado run --replay f1b1 --replay-data-dir /tmp/avocado_results
JOB ID     : 19c76abb29f29fe410a9a3f4f4b66387570edffa
SRC JOB ID : f1b1c870ad892eac6064a5332f1bbe38cda0aaf3
JOB LOG    : $HOME/avocado/job-results/job-2016-01-11T22.15-19c76ab/job.log
 (1/1) /bin/true: PASS (0.01 s)
RESULTS    : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0
JOB TIME   : 0.11 s
JOB HTML   : $HOME/avocado/job-results/job-2016-01-11T22.15-19c76ab/html/results.html
