/*
* Testing the parser is non trivial, especially since we can not call
* parser functionality directly in compiled code tests.
* All the tests (except the fuzzy tests at the end) follow the same schemata:
* a) create an nsIContentSecurityPolicy object
* b) set the selfURI in SetRequestContextWithPrincipal
* c) append one or more policies by calling AppendPolicy
* d) check if the policy count is correct by calling GetPolicyCount
* e) compare the result of the policy with the expected output
* using the struct PolicyTest;
*
* In general we test:
* a) policies that the parser should accept
* b) policies that the parser should reject
* c) policies that are randomly generated (fuzzy tests)
*
* Please note that fuzzy tests are *DISABLED* by default and shold only
* be run *OFFLINE* whenever code in nsCSPParser changes.
* To run fuzzy tests, flip RUN_OFFLINE_TESTS to 1.
