Selenium on Rails is just plain awesome, providing an web testing interface that doesn’t interfere with your main code. That said, there’s a Firefox plugin called Selenium IDE that records your actions in Firefox and generates tests for use with Selenium, how cool is that!
The only problem is, Selenium IDE doesn’t output in RSelenese and having to port one of their supported formats (Ruby Selenium) is a pain. So what do you do? Install the RSelenese plugin of course!
Here are the steps:
Then paste the following code:
/*
* Selenium on Rails RSelenese format for Selenium IDE
*
* Written by Shinya Kasatani (kasatani at gmail.com)
*/
load('formatCommandOnlyAdapter.js');
function string(value) {
if (value != null) {
value = value.replace(/\\/g, '\\\\');
value = value.replace(/\"/g, '\\"');
value = value.replace(/\r/g, '\\r');
value = value.replace(/\n/g, '\\n');
return '"' + value + '"';
} else {
return '""';
}
}
function underscore(text) {
return text.replace(/[A-Z]/g, function(str) {
return '_' + str.toLowerCase();
});
}
function formatCommand(command) {
var line = underscore(command.command);
if (command.target) {
line += ' ' + string(command.target);
if (command.value) {
line += ', ' + string(command.value);
}
}
return line;
}
this.playable = false;

If you’d wanna tweak the generated RSelenese code, here’s a handy reference:

Enjoy!
