This extension provides the ability to modify exception message text. While initially created to remove superfluous debug information from WebDriver exception messages, it could be used for translating exception messages to other languages.

The easiest way to configure is to use the @Extension annotation on an TranslatorExtension instance field within the fixture class. For example:

For example, the following code configures the extension to remove text from the exception message starting from the string "Debug info:".

    @Extension
    public ConcordionExtension extension = 
        new TranslatorExtension(new ExampleMessageTranslator());

where ExampleMessageTranslator is:

    public class ExampleMessageTranslator() implements MessageTranslator {
            
        @Override
        public String translate(String originalMessage) {
            int debugInfoStart = originalMessage.indexOf("Build info:");
            if (debugInfoStart > 0) {
                return originalMessage.substring(0, debugInfoStart);
            }
            return originalMessage;
        }
    }
