Can I create a junit environment without file system and network access? I want to enforce stricter rules for our test cases.
Ideally, this would be configurable with maven and work for the default test phase.

Based on this answer https://stackoverflow.com/a/309427/116509, I think you could set a
SecurityManageron test setup and restore the original on teardown.However, IMHO, some unit tests should be allowed to touch the file system, if for example the class under test actually creates files as part of its contract. (You can use dependency injection to make sure the files are created in a temp directory). Likewise, a good unit test of a class that uses HTTP should test it against an HTTP endpoint. Otherwise you just end up mocking everything and your test becomes worthless. I suppose the default should be to deny access, and then a developer would need to specifically override the permissions for this kind of test.
