Test2::Util::Trace(3)

NAME
Test2::Util::Trace - Debug information for events

DESCRIPTION
The Test2::API::Context object, as well as all Test2::Event types need to have access to information about where they were created. This object represents that information.

SYNOPSIS
    use Test2::Util::Trace;

    my $trace = Test2::Util::Trace->new(
        frame => [$package, $file, $line, $subname],
    );

METHODS

$trace->set_detail($msg)
$msg = $trace->detail
    Used to get/set a custom trace message that will be used INSTEAD of "at <FILE> line <LINE>" when calling "$trace->debug".

$str = $trace->debug
    Typically returns the string "at <FILE> line <LINE>". If "detail" is set then its value will be returned instead.

$trace->alert($MESSAGE)
    This issues a warning at the frame (filename and line number where errors should be reported).

$trace->throw($MESSAGE)
    This throws an exception at the frame (filename and line number where errors should be reported).

$frame = $trace->frame()
    Get the call frame arrayref.

($package, $file, $line, $subname) = $trace->call()
    Get the caller details for the debug-info. This is where errors should be reported.

$pkg = $trace->package
    Get the debug-info package.

$file = $trace->file
    Get the debug-info filename.

$line = $trace->line
    Get the debug-info line number.

$subname = $trace->subname
    Get the debug-info subroutine name.

$hashref = $t->TO_JSON
    This returns a hashref suitable for passing to the "Test2::Util::Trace->from_json" constructor. It is intended for use with the JSON family of modules, which will look for a "TO_JSON" method when "convert_blessed" is true.

$t = Test2::Util::Trace->from_json(%$hashref)
    Given the hash of data returned by "$t->TO_JSON", this method returns a new trace object of the appropriate subclass.
