    jasmine-matcher-errors

    Customize the error message reported by a custom jasmine matcher.

    Why?

    The message returned by a custom jasmine matcher is duplicated into the error object created for the failed spec. This results in error messages always being output twice.

    Once you can customize the error message you could keep the message brief, and put more detailed information in the error message, or whatever makes sense for your custom matcher.
