Currently, that means Weasel::Driver::Selenium2. Other driver implementations, such as Sahi can be independently developed and uploaded to \s-1CPAN,\s0 or contributed. (We welcome and encourage both!) .SS "\s-1DIFFERENCES WITH OTHER FRAMEWORKS\s0" .IX Subsection "DIFFERENCES WITH OTHER FRAMEWORKS" .IP "Mnemonics for element lookup patterns" 4 .IX Item "Mnemonics for element lookup patterns" The central registry of xpath expressions to find common page elements helps to keep page access code clean. E.g. compare: .Sp .Vb 2 \& use Weasel::FindExpanders::HTML; \& $session\->page\->find(\*(Aq*contains\*(Aq, text => \*(AqSome text\*(Aq); .Ve .Sp With .Sp .Vb 2 \& $session\->page\->find(".//*[contains(.,\*(AqSome text\*(Aq)] \& [not(.//*[contains(.,\*(AqSome text\*(Aq)])]"); .Ve .Sp Multiple patterns can be registered for a single mnemonic, which will be concatenated to a single xpath expression to find the matching tags in a single driver query. .Sp Besides good performance, this has the benefit that the following .Sp .Vb 1 \& $session\->page\->find(\*(Aq*button\*(Aq, text => \*(AqClick!\*(Aq); .Ve .Sp can be easily extended to match Dojo toolkit's buttons, which on the \s-1HTML\s0 level don't contain visible button or input tags, simply by using the widget support set: .Sp .Vb 1 \& use Weasel::Widgets::Dojo; .Ve .IP "Widgets encapsulate specific behaviours" 4 .IX Item "Widgets encapsulate specific behaviours" All elements in \f(CW\*(C`Weasel\*(C'\fR are of the base type \f(CW\*(C`Weasel::Element\*(C'\fR, which encapsulates the regular element interactions (click, find children, etc). .Sp While most elements will be represented by \f(CW\*(C`Weasel::Element\*(C'\fR, it's possible to implement other wrappers. These offer a logical extension point to implement tag-specific utility functions. E.g. \&\f(CW\*(C`Weasel::Widgets::HTML::Select\*(C'\fR, which adds the utility function \&\f(CW\*(C`select_option\*(C'\fR. .Sp These widgets also offer a good way to override default behaviours. One such case is the Dojo implementation of a 'select' element. This element replaces the select tag entirely and in contrast with the original, doesn't keep the options as child elements of the 'select'\-replacing tag. By using the Dojo widget library .Sp .Vb 1 \& use Weasel::Widget::Dojo; .Ve .Sp the lack of the parent/child relation between the the select and its options is transparently handled by overriding the widget's \f(CW\*(C`find\*(C'\fR and \f(CW\*(C`find_all\*(C'\fR methods. .SH "DEPENDENCIES" .IX Header "DEPENDENCIES" .IP "\s-1KEYS\s0" 4 .IX Item "KEYS" Returns a reference to a hash with names of the keys in the hash keys and single-character strings containing the key codes as the values. .SH "ATTRIBUTES" .IX Header "ATTRIBUTES" .IP "default_session" 4 .IX Item "default_session" The name of the default session to return from \f(CW\*(C`session\*(C'\fR, in case no name argument is provided. .IP "sessions" 4 .IX Item "sessions" Holds the sessions registered with the \f(CW\*(C`Weasel\*(C'\fR instance. .SH "SUBROUTINES/METHODS" .IX Header "SUBROUTINES/METHODS" .ie n .IP "session([$name [, $value]])" 4 .el .IP "session([$name [, \f(CW$value\fR]])" 4 .IX Item "session([$name [, $value]])" Returns the session identified by \f(CW$name\fR. .Sp If \f(CW$value\fR is specified, it's associated with the given \f(CW$name\fR. .SH "AUTHOR" .IX Header "AUTHOR" .Vb 1 \& Erik Huelsmann .Ve .SH "CONTRIBUTORS" .IX Header "CONTRIBUTORS" .Vb 2 \& Erik Huelsmann \& Yves Lavoie .Ve .SH "MAINTAINERS" .IX Header "MAINTAINERS" .Vb 1 \& Erik Huelsmann .Ve .SH "BUGS AND LIMITATIONS" .IX Header "BUGS AND LIMITATIONS" Bugs can be filed in the GitHub issue tracker for the Weasel project: .SH "SOURCE" .IX Header "SOURCE" The source code repository for Weasel is at https://github.com/perl\-weasel/weasel .SH "SUPPORT" .IX Header "SUPPORT" Community support is available through perl\-weasel@googlegroups.com . .SH "BUGS" .IX Header "BUGS" Bugs can be filed in the GitHub issue tracker for the Weasel project: .SH "SOURCE" .IX Header "SOURCE" The source code repository for Weasel is at .SH "SUPPORT" .IX Header "SUPPORT" Community support is available through perl\-weasel@googlegroups.com . .SH "LICENSE AND COPYRIGHT" .IX Header "LICENSE AND COPYRIGHT" .Vb 1 \& (C) 2016\-2023 Erik Huelsmann .Ve .PP Licensed under the same terms as Perl.
