|
* Unit coverage for plugin_monitor_csp_nonce().
|
|
*
|
|
* The helper has two branches that hinge on whether Cacti's global
|
|
* CactiSecureHeaders class is present. A single PHP process can only ever
|
|
* see the class as present or absent, never both, so the class-present
|
|
* branch is exercised in an isolated child process that defines a
|
|
* controlled double, rather than by mutating global state in this process
|
|
* or asserting on the source text.
