  77. =head1 NAME
  78. Test::Selenium::Remote::Driver
  79. =head1 DESCRIPTION
  80. A subclass of L<Selenium::Remote::Driver>. which provides useful testing
  81. functions.
  82. This is an I<experimental> addition to the Selenium::Remote::Driver
  83. distribution, and some interfaces may change.
  84. =head1 Methods
  85. =head2 new ( %opts )
  86. This will create a new Test::Selenium::Remote::Driver object, which subclasses
  87. L<Selenium::Remote::Driver>. This subclass provides useful testing
  88. functions. It is modeled on L<Test::WWW::Selenium>.
  89. Environment vars can be used to specify options to pass to
  90. L<Selenium::Remote::Driver>. ENV vars are prefixed with C<TWD_>.
  91. ( After the old fork name, "Test::WebDriver" )
  92. Set the Selenium server address with C<$TWD_HOST> and C<$TWD_PORT>.
  93. Pick which browser is used using the C<$TWD_BROWSER>, C<$TWD_VERSION>,
  94. C<$TWD_PLATFORM>, C<$TWD_JAVASCRIPT>, C<$TWD_EXTRA_CAPABILITIES>.
  95. See L<Selenium::Driver::Remote> for the meanings of these options.

  111. =head2 server_is_running( $host, $port )
  112. Returns true if a Selenium server is running. The host and port
  113. parameters are optional, and default to C<localhost:4444>.
  114. Environment vars C<TWD_HOST> and C<TWD_PORT> can also be used to
  115. determine the server to check.

  522. =head1 NOTES
  523. This module was forked from Test::WebDriver 0.01.
  524. For Best Practice - I recommend subclassing Test::Selenium::Remote::Driver for your application,
  525. and then refactoring common or app specific methods into MyApp::WebDriver so that
  526. your test files do not have much duplication. As your app changes, you can update
  527. MyApp::WebDriver rather than all the individual test files.
