+# Test Standards
+
+- Test naming: `test_[system]_[scenario]_[expected_result]` pattern
+- Every test must have a clear arrange/act/assert structure
+- Unit tests must not depend on external state (filesystem, network, database)
+- Integration tests must clean up after themselves
+- Performance tests must specify acceptable thresholds and fail if exceeded
+- Test data must be defined in the test or in dedicated fixtures, never shared mutable state
+- Mock external dependencies — tests should be fast and deterministic
+- Every bug fix must have a regression test that would have caught the original bug
+
+## Examples
+
+**Correct** (proper naming + Arrange/Act/Assert):
+
+```gdscript
+func test_health_system_take_damage_reduces_health() -> void:
+    # Arrange
+    var health := HealthComponent.new()
+    health.max_health = 100
+    health.current_health = 100
+
+    # Act
+    health.take_damage(25)
+
+    # Assert
+    assert_eq(health.current_health, 75)
+```
+
+**Incorrect**:
+
+```gdscript
+func test1() -> void:  # VIOLATION: no descriptive name
+    var h := HealthComponent.new()
+    h.take_damage(25)  # VIOLATION: no arrange step, no clear assert
+    assert_true(h.current_health < 100)  # VIOLATION: imprecise assertion
+```
