Module 2 Expansion Drop: Frothing Berserker

The lesson's Expansion Drop beat explains the task. This file holds the scenario, the test locations and the check.

• Card: Frothing Berserker, 3-mana 2/4, "Whenever a minion takes damage, gain +1 Attack." (Frothing Berserker, hearthstone.wiki.gg).
• Tests: tests/rust/test_02x.rs and tests/ts/test_02x.test.ts. Copy the one for your track into your workspace's tests/.
• Reference answer: solution/rust/src/content/mod.rs and solution/ts/src/content/index.ts. Each is the Module 2 reference content with one card added. Nothing under src/engine/ changes, and neither does the harness.
• Check: commit your workspace before you start, then run node tools/expansion-check.mjs <your-workspace> <that-commit> from the course repository. It fails if any file under src/engine/ changed.

Scenario

test_02x_frothing_counts_each_damage

• Setup: an empty game. Summon Frothing Berserker for player 0 (id F), then a Test Filler for player 0, then a Test Filler for player 1. Record attack(F).
• Action: player 0 casts Whirlwind.
• Assertions:
  • attack(F) is 3 more than before: three minions took damage (F itself and both Fillers, the enemy one included), so F triggers three times.
  • The log has exactly three Triggered events whose source is F.
