Detailed Description

Data-driven tests for ALL 869 spell_proc entries.

Tests proc calculations for every spell_proc entry:

• Cooldown blocking behavior
• Chance calculation with level reduction
• Attribute flag validation

This complements SpellProcDataDrivenTest.cpp which tests CanSpellTriggerProcOnEvent().

---

DESIGN NOTE: Why Tests Skip Certain Entries

This test file uses parameterized tests that run against ALL 869 spell_proc entries. Each test validates a specific feature (cooldowns, level reduction, attribute flags, etc.). Tests use GTEST_SKIP() for entries that don't have the feature being tested.

For example (current counts from test output):

• CooldownBlocking_WhenCooldownSet: Tests 246 entries with Cooldown > 0 (skips 623)
• Level60Reduction_WhenAttributeSet: Tests entries with PROC_ATTR_REDUCE_PROC_60 (0 currently)
• UseStacksForCharges_Behavior: Tests entries with PROC_ATTR_USE_STACKS_FOR_CHARGES (0 currently)
• TriggeredCanProc_FlagSet: Tests 73 entries with PROC_ATTR_TRIGGERED_CAN_PROC (skips 796)
• ReqManaCost_FlagSet: Tests 5 entries with PROC_ATTR_REQ_MANA_COST (skips 864)

This is INTENTIONAL. Running parameterized tests against all entries ensures:

1. Every entry is validated for applicable features
2. Statistics show exact coverage (X entries with feature Y)
3. New entries added to spell_proc are automatically tested
4. Regression detection if an entry unexpectedly gains/loses a feature

The statistics tests at the bottom output the exact counts: "[ INFO ] Entries with cooldown: 85 / 869" "[ INFO ] Entries with REDUCE_PROC_60: 15 / 869" etc.

SKIPPED tests are expected and correct. Each skip message includes:

• The SpellId being skipped

- The reason (e.g., "has no cooldown", "doesn't have REDUCE_PROC_60")
