App::Yath::Plugin - Base class for yath plugins
This is a base class for yath plugins. Note this class also subclasses
Test2::Harness::Plugin.
This class holds the methods specific to yath, which is the UI layer.
Test2::Harness::Plugin holds the methods specific to Test2::Harness which is
the backend.
package App::Yath::Plugin::MyPlugin;
use parent 'App::Yath::Plugin';
# ... Define methods
1;
Then to use it at the command line:
$ yath -pMyPlugin ...
None of the plugin base classes provide a "new()" method. By default
plugins are not instantiated and only the plugin package name is passed
around. All methods are then called on the class.
If you want your plugin to be instantiated as an object you need only define a
"new()" method. If this method is defined yath will call it and
create an instance. The instance created will then be used when calling all
the methods.
To pass arguments to the constructor you can use "yath
-pYourPlugin=arg1,arg2,arg3...". Your plugin can also define options
using App::Yath::Options which will be dropped into the $settings that get
passed around.
Note: See Test2::Harness::Plugin for additional method you can
implement/override
- $plugin->handle_event($event, $settings)
- Called for every single event that yath sees. Note that
this method is not defined by default for performance reasons, however it
will be called if you define it.
- @sorted = $plugin->sort_files_2(settings =>
$settings, files => \@unsorted)
- This gives your plugin a chance to sort the files before
they are added to the queue. Other things are done later to re-order the
files optimally based on length or category, so this sort is just for
initial job numbering, and to define a base order before optimization
takes place.
All files to sort will be instances of Test2::Harness::TestFile.
This method is normally left undefined, but will be called if you define it.
If this is present then "sort_files()" will be ignored.
- @sorted = $plugin->sort_files(@unsorted)
-
DEPRECATED Use "sort_files_2()" instead.

- $plugin->finish(%args)
- This is what arguments are recieved:
(
settings => $settings, # The settings
final_data => $final_data, # See below
pass => $pass ? 1 : 0, # Always a 0 or 1
tests_seen => $self->{+TESTS_SEEN} // 0, # Integer 0 or greater
asserts_seen => $self->{+ASSERTS_SEEN} // 0, # Integer 0 or greater
)
The final_data looks like this, note that some data may not be present if it
is not applicable. The data structure can be as simple as "{ pass
=> $bool }".
{
pass => $pass, # boolean, did the test run pass or fail?
failed => [ # Jobs that failed, and did not pass on a retry
[$job_id1, $file1], # Failing job 1
[$job_id2, $file2], # Failing job 2
...
],
retried => [ # Jobs that failed and were retried
[$job_id1, $times_run1, $file1, $passed_eventually1], # Passed_eventually is a boolean
[$job_id2, $times_run2, $file2, $passed_eventually2],
...
],
hatled => [ # Jobs that caused the entire test suite to halt
[$job_id1, $file1, $halt_reason1], # halt_reason is a human readible string
[$job_id2, $file2, $halt_reason2],
],
}
- $plugin->finalize($settings)
- This is called as late as possible before exit. This is
mainly useful for outputting messages such as "Extra log file written
to ..." which are best put at the end of output.
