Did you read this documentation?
http://maven.apache.org/surefire/maven-surefire-plugin/examples/single-test.html

The hash mark is class#method separator.
Then the quotation mark splits in two where.
Why you use quotations if class name and method name do not use the quotation marks?

> i noticed earlier that maven might do some black-magic with these regexps in the background ( i know that it should know the class name earlier; to avoid starting testcases which will get entirely excluded...and thats cool )
> ...so..i assume maven does split the regex by the {{#}}; and that's okay - if that can't be avoided; place some pointers in the documentation about it and/or a more descriptive exception could be useful
