1. This link no longer exists. https://docs.jboss.org/author/display/WFLY10/Testsuite
2. There is no, "header describing the purpose of the pom and what should and should not go in it" – file testsuite/integration/pom.xml.
3. There is no directory "src/test/resources/test-configs/", and the concept is not valid
4. There is no directory src/test/scripts. There is only testsuite/scripts
5. The directory structure described does not reflect that existing structure
   The existing structure is
   testsuite/integration/basic/src/test/java/org/jboss/as/test/integration/security
6. The profile names in testsuite/pom.xml are not as described in the doc
   (e.g. clustering.integration.tests.profile) but profile id is
   integ-clustering.module.profile
7. There is no description of how "*.cli" files are handled and when
   to use them and where they are to reside.
8. There is no description as to how to run a single test file.

None of the 'common' profiles are described, i.e. the ones that we use to drive CI. This can somewhat be covered in the root README for the project, but in this case duplication is worthwhile.

I'm sure many other things, as I think this file is probably a decade behind.
