NAME
Test2::Harness::Log - Documentation about the Test2::Harness log file.
DESCRIPTION
Test2::Harness aka App::Yath produces a rich/complete log when asked to do so. This module documents the
log format.
COMPRESSION
Test2::Harness can output log files uncompressed, compressed in gzip, or compressed in bzip2.
FORMAT
The log file is in jsonl format. Each line of the log can be indepentantly parsed as json. Each line
represents a single event Test2::Harness processed during a run. These events will be in the original
order Test2::Harness processed them in (may not be chronological to when they were generated as
generation, collection, processing, and rendering are handled in different processes. A complete log will
be terminated by the string "null", which is also valid json. If a log is missing this terminator it is
considered an incomplete log.
EVENTS
Please note: Older versions of Test2::Harness produced less complete events, this covers all current
fields, if you are attempting to handle very old logs some of these fields may be missing.
Each event will have the following fields:
{
"event_id" : "CD01CD30-D535-11EA-9B6A-D90F9664FE12",
"job_id" : 0,
"job_try" : null,
"run_id" : "CCF98E54-D535-11EA-915A-D70F9664FE12",
"stamp" : 1596423763.76517,
"facet_data" : {
"harness" : {
"event_id" : "CD01CD30-D535-11EA-9B6A-D90F9664FE12",
"job_id" : 0,
"job_try" : null,
"run_id" : "CCF98E54-D535-11EA-915A-D70F9664FE12"
},
...
}
}
event_id : "UUID_OR_STRING"
Typically this will be a UUID, but when UUIDs cannot be generated it may have a different unique
identifier. This will always be a string. This may never be NULL, if it is NULL then that is a bug
and should be reported.
job_id : "0_OR_UUID_OR_STRING"
ID 0 is special in that it represents the test harness itself, and not an actual test being run.
Normally the job_id will be a UUID, but may be another unique string if UUID generation is disabled
or not available.
job_try : INTEGER_OR_NULL
For "job_id => 0" this will be "NULL" for any other job this will be an intgeger of 0 or greater.
This is 0 for the first time a test job is run, if a job is re-run due to failure (or any other
reason) this will be incremented to tell you what run it is. When a job is re-run it keeps the same
job ID, you can use this to distinguish events from each run of the job.
run_id : "UUID_OR_STRING"
This is the run_id of the entire yath test run. This should be the same for every event in any given
log.
stamp : UNIX_TIME_STAMP
Timestamp of the event. This is NORMALLY set when an event is generated, however if an event does not
have its own time stamp yath will give it a timestamp upon collection. Events without timestamps
happen if the test outputs TAP instead of Test2::Event objects, or if a tool misbehaves in some way.
facet_data : HASH
This contains all the the data of the event, such as if an assertion was made, what file name and
line number generated it, etc.
In addition to the original facets of the event, Test2::Harness may inject the following facets (or
generate completely new events to convey these facets).
harness_final
This will contain the final summary data from the end of the test run.
{
# Was the test run a success, or were there failures?
pass => $BOOL,
# What tests failed?
failed => [
[
$job_id, # Job id of the job that failed
$file, # Test filename
],
...
],
# What tests had to be retried, and did they eventually pass?
retried => [
[
$job_id, # Job id of the job that was retied
$tries, # Number of tries attempted
$file, # Test filename
$eventually_passed, # 'YES' if it eventually passed, 'NO' if no try ever passed.
],
...
],
# What tests setn a halt event (such as bail-out, or skip the rest)
halted => [
[
$job_id, # Job id of the test
$file, # Test filename
$halt, # Halt code
],
...
],
# What tests were never run (maybe because of a bail-out, or an internal error)
unseen => [
[
$job_id, # Job id of the test
$file, # Test filename
],
...
],
}
harness_watcher
Internal use only, subject to change, do not rely on it.
harness_job
A hash representation of an Test2::Harness::Runner::Job object.
Note: This is done via a transformation, several methods have their values stored in this hash
when the original object does not directly store them.
harness_job_end
{
file => $provided_path_to_test_file,
rel_file => $relative_path_to_test_file,
abs_file => $absolute_path_to_test_file,
fail => $BOOL,
retry => $INTEGER, # Number of retries left
stamp => $UNIX_TIMESTAMP, # Timestamp of when the test completed
# May not be present
skip => $STRING, # Reason test was skipped (if it was skipped)
times => $TIMING_DATA, # See below
}
The "times" field is populated by calling "data_dump()" on an
Test2::Harness::Auditor::TimeTracker Object.
harness_job_exit
This represents when the test job exited.
{
exit => $WSTAT,
retry => $INTEGER
stamp => $UNIX_TIMESTAMP
}
harness_job_fields
Extra data attached to the harness job, usually from an Test2::Harness::Plugin via
"inject_run_data()".
harness_job_launch
This facet is almost always in the same event as the "harness_job_start" facet. NOTE: While
writing these docs the author wonders if this facet is unnecessary...
{
stamp => $UNIX_TIMESTAMP,
rety => $INTEGER,
}
harness_job_queued
This data is produced by the "queue_item" method in Test2::Harness::TestFile.
This contains the data about a test job conveyed by the queue. This usually contains data that
will later be used by Test2::Harness::Runner::Job. It is better to use the "harness_job" facet,
which contains the final data used to run the job.
The following 3 fields are the only ones likely to be useful to most people:
{
file => $ORIGINAL_PATH_TO_FILE,
job_id => $UUID_OR_STRING,
stamp => $UNIX_TIMESTAMP,
}
harness_job_start
This facet is sent in an event as soon as a job starts. The data in this facet is mainly intended
to convey necessary information to a renderer so that it can render the fact that a job started.
{
file => $provided_path_to_test_file,
rel_file => $relative_path_to_test_file,
abs_file => $absolute_path_to_test_file,
stamp => $UNIX_TIMESTAMP, # Timestamp of when the test completed
job_id => $UUID_OR_STRING,
details => "Job UUID_OR_STRING started at $UNIX_TIMESTAMP",
}
harness_run
A hash representation of an Test2::Harness::Run object.
