Test::Valgrind::Tool(3) Base class for Test::Valgrind tools.


Version 1.18


This class is the base for Test::Valgrind tools.

They wrap around "valgrind" tools by parsing its output and sending reports to the parent session whenever an error occurs. They are expected to function both in suppressions generation and in analysis mode.



    my $required_version = $tvt->requires_version;

The minimum "valgrind" version needed to run this tool. Defaults to 3.1.0.


    my $tvt = Test::Valgrind::Tool->new(tool => $tool);

Creates a new tool object of type $tool by requiring and redispatching the method call to the module named $tool if it contains '::' or to "Test::Valgrind::Tool::$tool" otherwise. The class represented by $tool must inherit this class.


    my $tvt_train = Test::Valgrind::Tool->new_trainer;

Creates a new tool object suitable for generating suppressions.

Defaults to return "undef", which skips suppression generation.


    my $parser_class = $tvt->parser_class($session);

Returns the class from which the parser for this tool output will be instanciated.

This method must be implemented when subclassing.


    my $report_class = $tvt->report_class($session);

Returns the class in which suppression reports generated by this tool will be blessed.

This method must be implemented when subclassing.


    my @args = $tvt->args($session);

Returns the list of tool-specific arguments that are to be passed to "valgrind". All the suppression arguments are already handled by the session.

Defaults to the empty list.


    my $tag = $tvt->suppressions_tag($session);

Returns a identifier that will be used to pick up the right suppressions for running the tool, or "undef" to indicate that no special suppressions are needed.

This method must be implemented when subclassing.



Called when the $session starts.

Defaults to set ``started'' in Test::Valgrind::Component.


    my $filtered_report = $tvt->filter($session, $report);

The $session calls this method after receiving a report from the parser and before letting the command filter it. You can either return a mangled $report (which does not need to be a clone of the original) or "undef" if you want the action to ignore it completely.

Defaults to the identity function.



Called when the $session finishes.

Defaults to clear ``started'' in Test::Valgrind::Component.
