Please use the following syntaxe: ./run.sh where should be the url to a WPS Server and should be the service name you want to run tests with. For instance to test the Buffer service on a localhost WPS server, use the following command: ./run.sh http://localhost/cgi-bin/zoo_loader.cgi Buffer Important note: sometimes XML validation failed because xmllint is unable to download a file required to validate. In such case, you can use the file /etc/xml/catalog on your local machine to use a local copy of the missing file. For instance, in case xml.xsd can't be downloaded, then you can download a copy using this url http://www.w3.org/2001/xml.xsd, store it in /etc/schemas directory and then use the following /etc/xml/catalog file: Obviously, you can do similar manipulation for the OGC schemas to use local files rather than downloading them for each tests.
