HTML report generation fails for Spock-based tests with 'File name too long' IOException #230

Closed marek-parfianowicz closed 5 months ago

marek-parfianowicz commented 5 months ago

Problem originally reported for version 4.5.1.

A file name picked for a test result page might exceed Linux/Windows file name limit of 255 characters. This in particular happens for Spock-based tests, where a runtime test name contains all input arguments, both types and values.
