/* Embedded DSL for automated black-box testing of battle mechanics.
 *
 * To run all the tests use:
 *     make check -j
 * To run specific tests, e.g. Spikes ones, use:
 *     make check TESTS="Spikes"
 * To build a ROM (pokemerald-test.elf) that can be opened in mgba to
 * view specific tests, e.g. Spikes ones, use:
 *     make pokeemerald-test.elf TESTS="Spikes"
 *
 * Manually testing a battle mechanic often follows this pattern:
 * 1. Create a party which can activate the mechanic.
 * 2. Start a battle and play a few turns which activate the mechanic.
 * 3. Look at the UI outputs to decide if the mechanic works.
 *
 * Automated testing follows the same pattern:
 * 1. Initialize the party in GIVEN.
 * 2. Play the turns in WHEN.
 * 3. Check the UI outputs in SCENE.
 *
 * As a concrete example, to manually test EFFECT_PARALYZE, e.g. the
 * effect of Stun Spore you might:
 * 1. Put a Wobbuffet that knows Stun Spore in your party.
 * 2. Battle a wild Wobbuffet.
 * 3. Use Stun Spore.
 * 4. Check that the Wobbuffet is paralyzed.
 *
 * This can be translated to an automated test as follows:
 *
 *   ASSUMPTIONS
 *   {
 *       ASSUME(gMovesInfo[MOVE_STUN_SPORE].effect == EFFECT_PARALYZE);
 *   }
 *
 *   SINGLE_BATTLE_TEST("Stun Spore inflicts paralysis")
 *   {
 *       GIVEN {
 *           PLAYER(SPECIES_WOBBUFFET); // 1.
 *           OPPONENT(SPECIES_WOBBUFFET); // 2.
 *       } WHEN {
 *           TURN { MOVE(player, MOVE_STUN_SPORE); } // 3.
 *       } SCENE {
 *           ANIMATION(ANIM_TYPE_MOVE, MOVE_STUN_SPORE, player);
 *           MESSAGE("Foe Wobbuffet is paralyzed! It may be unable to move!"); // 4
 *           STATUS_ICON(opponent, paralysis: TRUE); // 4.
 *       }
 *   }
 *
 * The ASSUMPTIONS block documents that Stun Spore has EFFECT_PARALYZE.
 * If Stun Spore did not have that effect it would cause the tests in
 * the file to be skipped. We write our tests like this so that hackers
 * can change the effects of moves without causing tests to fail.
 *
 * SINGLE_BATTLE_TEST defines the name of the test. Related tests should
 * start with the same prefix, e.g. Stun Spore tests should start with
 * "Stun Spore", this allows just the Stun Spore-related tests to be run
 * with:
 *     make check TESTS="Stun Spore"
 *
 * GIVEN initializes the parties, PLAYER and OPPONENT add a Pokémon to
 * their respective parties. They can both accept a block which further
 * customizes the Pokémon's stats, moves, item, ability, etc.
 *
 * WHEN describes the turns, and TURN describes the choices made in a
 * single turn. MOVE causes the player to use Stun Spore and adds the
 * move to the Pokémon's moveset if an explicit Moves was not specified.
 * Pokémon that are not mentioned in a TURN use Celebrate.
 * The test runner rigs the RNG so that unless otherwise specified,
 * moves always hit, never critical hit, always activate their secondary
 * effects, and always roll the same damage modifier.
 *
 * SCENE describes the player-visible output of the battle. In this case
 * ANIMATION checks that the Stun Spore animation played, MESSAGE checks
 * the paralysis message was shown, and STATUS_ICON checks that the
 * opponent's HP bar shows a PRZ icon.
 *
 * As a second example, to manually test that Stun Spore does not effect
 * Grass-types you might:
 * 1. Put a Wobbuffet that knows Stun Spore in your party.
 * 2. Battle a wild Oddish.
 * 3. Use Stun Spore.
 * 4. Check that the move animation does not play.
 * 5. Check that a "It doesn't affect Foe Oddish…" message is shown.
 *
 * This can again be translated as follows:
 *
 *   SINGLE_BATTLE_TEST("Stun Spore does not affect Grass-types")
 *   {
 *       GIVEN {
 *           ASSUME(gMovesInfo[MOVE_STUN_SPORE].powderMove);
 *           ASSUME(gSpeciesInfo[SPECIES_ODDISH].types[0] == TYPE_GRASS);
 *           PLAYER(SPECIES_ODDISH); // 1.
 *           OPPONENT(SPECIES_ODDISH); // 2.
 *       } WHEN {
 *           TURN { MOVE(player, MOVE_STUN_SPORE); } // 3.
 *       } SCENE {
 *           NOT ANIMATION(ANIM_TYPE_MOVE, MOVE_STUN_SPORE, player); // 4.
 *           MESSAGE("It doesn't affect Foe Oddish…"); // 5.
 *       }
 *   }
 *
 * The ASSUMEs are documenting the reasons why Stun Spore does not
 * affect Oddish, namely that Stun Spore is a powder move, and Oddish
 * is a Grass-type. These ASSUMEs function similarly to the ones in
 * ASSUMPTIONS but apply only to the one test.
 *
 * NOT inverts the meaning of a SCENE check, so applying it to ANIMATION
 * requires that the Stun Spore animation does not play. MESSAGE checks
 * that the message was shown. The checks in SCENE are ordered, so
 * together this says "The doesn't affect message is shown, and the Stun
 * Spore animation does not play at any time before that". Normally you
 * would only test one or the other, or even better, just
 * NOT STATUS_ICON(opponent, paralysis: TRUE); to say that Oddish was
 * not paralyzed without specifying the exact outputs which led to that.
 *
 * As a final example, to test that Meditate works you might:
 * 1. Put a Wobbuffet that knows Meditate and Tackle in your party.
 * 2. Battle a wild Wobbuffet.
 * 3. Use Tackle and note the amount the HP bar reduced.
 * 4. Battle a wild Wobbuffet.
 * 5. Use Meditate and that the stat change animation and message play.
 * 6. Use Tackle and check that the HP bar reduced by more than in 3.
 *
 * This can be translated to an automated test as follows:
 *
 *    SINGLE_BATTLE_TEST("Meditate raises Attack", s16 damage)
 *    {
 *        bool32 raiseAttack;
 *        PARAMETRIZE { raiseAttack = FALSE; }
 *        PARAMETRIZE { raiseAttack = TRUE; }
 *        GIVEN {
 *            ASSUME(gMovesInfo[MOVE_TACKLE].category == DAMAGE_CATEGORY_PHYSICAL);
 *            PLAYER(SPECIES_WOBBUFFET);
 *            OPPONENT(SPECIES_WOBBUFFET);
 *        } WHEN {
 *            if (raiseAttack) TURN { MOVE(player, MOVE_MEDITATE); } // 5.
 *            TURN { MOVE(player, MOVE_TACKLE); } // 3 & 6.
 *        } SCENE {
 *            if (raiseAttack) {
 *                ANIMATION(ANIM_TYPE_MOVE, MOVE_MEDITATE, player);
 *                ANIMATION(ANIM_TYPE_GENERAL, B_ANIM_STATS_CHANGE, player); // 5.
 *                MESSAGE("Wobbuffet's attack rose!"); // 5.
 *            }
 *            ANIMATION(ANIM_TYPE_MOVE, MOVE_TACKLE, player);
 *            HP_BAR(opponent, captureDamage: &results[i].damage); // 3 & 6.
 *        } FINALLY {
 *            EXPECT_MUL_EQ(results[0].damage, Q_4_12(1.5), results[1].damage); // 6.
 *        }
 *    }
 *
 * PARAMETRIZE causes a test to run multiple times, once per PARAMETRIZE
 * block (e.g. once with raiseAttack = FALSE and once with raiseAttack =
 * TRUE).
 * HP_BAR's captureDamage causes the change in HP to be stored in a
 * variable, and the variable chosen is results[i].damage. results[i]
 * contains all the variables defined at the end of SINGLE_BATTLE_TEST,
 * i is the current PARAMETRIZE index.
 * FINALLY runs after the last parameter has finished, and uses
 * EXPECT_MUL_EQ to check that the second battle deals 1.5× the damage
 * of the first battle (with a small tolerance to account for rounding).
 *
 * You might notice that all the tests check the outputs the player
 * could see rather than the internal battle state. e.g. the Meditate test
 * could have used gBattleMons[B_POSITION_OPPONENT_LEFT].hp instead of
 * using HP_BAR to capture the damage. This is a deliberate choice, by
 * checking what the player can observe the tests are more robust to
 * refactoring, e.g. if gBattleMons got moved into gBattleStruct then
 * any test that used it would need to be updated.
 *
 * REFERENCE
 * =========
 *
 * ASSUME(cond)
 * Causes the test to be skipped if cond is false. Used to document any
 * prerequisites of the test, e.g. to test Burn reducing the Attack of a
 * Pokémon we can observe the damage of a physical attack with and
 * without the burn. To document that this test assumes the attack is
 * physical we can use:
 *     ASSUME(gMovesInfo[MOVE_WHATEVER].category == DAMAGE_CATEGORY_PHYSICAL);
 *
 * ASSUMPTIONS
 * Should be placed immediately after any #includes and contain any
 * ASSUMEs which should apply to the whole file, e.g. to test
 * EFFECT_POISON_HIT we need to choose a move with that effect, if
 * we chose to use Poison Sting in every test then the top of
 * move_effect_poison_hit.c should be:
 *     ASSUMPTIONS
 *     {
 *         ASSUME(gMovesInfo[MOVE_POISON_STING].effect == EFFECT_POISON_HIT);
 *     }
 *
 * SINGLE_BATTLE_TEST(name, results...) and DOUBLE_BATTLE_TEST(name, results...)
 * Define single- and double- battles. The names should start with the
 * name of the mechanic being tested so that it is easier to run all the
 * related tests. results contains variable declarations to be placed
 * into the results array which is available in PARAMETRIZEd tests.
 * The main differences for doubles are:
 * - Move targets sometimes need to be explicit.
 * - Instead of player and opponent there is playerLeft, playerRight,
 *   opponentLeft, and opponentRight.
 *
 * AI_SINGLE_BATTLE_TEST(name, results...) and AI_DOUBLE_BATTLE_TEST(name, results...)
 * Define battles where opponent mons are controlled by AI, the same that runs
 * when battling regular Trainers. The flags for AI should be specified by
 * the AI_FLAGS command.
 * The rules remain the same as with the SINGLE and DOUBLE battle tests
 * with some differences:
 * - opponent's action is specified by the EXPECT_MOVE(s) / EXPECT_SEND_OUT / EXPECT_SWITCH commands
 * - we don't control what opponent actually does, instead we make sure the opponent does what we expect it to do
 * - we still control the player's action the same way
 * - apart from the EXPECTED commands, there's also a new SCORE_ and SCORE__VAL commands
 *
 * KNOWN_FAILING
 * Marks a test as not passing due to a bug. If there is an issue number
 * associated with the bug it should be included in a comment. If the
 * test passes the developer will be notified to remove KNOWN_FAILING.
 * For example:
 *     SINGLE_BATTLE_TEST("Jump Kick has no recoil if no target")
 *     {
 *         KNOWN_FAILING; // #2596.
 *
 * PARAMETRIZE
 * Runs a test multiple times. i will be set to which parameter is
 * running, and results will contain an entry for each parameter, e.g.:
 *     SINGLE_BATTLE_TEST("Blaze boosts Fire-type moves in a pinch", s16 damage)
 *     {
 *         u16 hp;
 *         PARAMETRIZE { hp = 99; }
 *         PARAMETRIZE { hp = 33; }
 *         GIVEN {
 *             ASSUME(gMovesInfo[MOVE_EMBER].type == TYPE_FIRE);
 *             PLAYER(SPECIES_CHARMANDER) { Ability(ABILITY_BLAZE); MaxHP(99); HP(hp); }
 *             OPPONENT(SPECIES_WOBBUFFET);
 *         } WHEN {
 *             TURN { MOVE(player, MOVE_EMBER); }
 *         } SCENE {
 *             HP_BAR(opponent, captureDamage: &results[i].damage);
 *         } FINALLY {
 *             EXPECT(results[1].damage > results[0].damage);
 *         }
 *     }
 *
 * PASSES_RANDOMLY(successes, trials, [tag])
 * Checks that the test passes successes/trials. If tag is provided, the
 * test is run for each value that the tag can produce. For example, to
 * check that Paralysis causes the turn to be skipped 25/100 times, we
 * can write the following test that passes only if the Pokémon is fully
 * paralyzed and specify that we expect it to pass 25/100 times when
 * RNG_PARALYSIS varies:
 *     SINGLE_BATTLE_TEST("Paralysis has a 25% chance of skipping the turn")
 *     {
 *         PASSES_RANDOMLY(25, 100, RNG_PARALYSIS);
 *         GIVEN {
 *             PLAYER(SPECIES_WOBBUFFET) { Status1(STATUS1_PARALYSIS); }
 *             OPPONENT(SPECIES_WOBBUFFET);
 *         } WHEN {
 *             TURN { MOVE(player, MOVE_CELEBRATE); }
 *         } SCENE {
 *             MESSAGE("Wobbuffet is paralyzed! It can't move!");
 *         }
 *     }
 * All BattleRandom calls involving tag will return the same number, so
 * this cannot be used to have two moves independently hit or miss, for
 * example.
 *
 * If the tag is not provided, runs the test 50 times and computes an
 * approximate pass ratio.
 *     PASSES_RANDOMLY(gMovesInfo[move].accuracy, 100);
 * Note that this mode of PASSES_RANDOMLY makes the tests run very
 * slowly and should be avoided where possible. If the mechanic you are
 * testing is missing its tag, you should add it.
 *
 * GIVEN
 * Contains the initial state of the parties before the battle.
 *
 * RNGSeed(seed)
 * Explicitly sets the RNG seed. Try to avoid using this because it is a
 * very fragile tool.
 * Example:
 *     GIVEN {
 *         RNGSeed(0xC0DEIDEA);
 *
 * FLAG_SET(flagId)
 * Sets the specified flag. Can currently only set one flag at a time.
 * Cleared between perameters and at the end of the test.
 * Example:
 *     GIVEN {
 *         FLAG_SET(FLAG_SYS_EXAMPLE_FLAG);
 *
 * PLAYER(species) and OPPONENT(species)
 * Adds the species to the player's or opponent's party respectively.
 * The Pokémon can be further customized with the following functions:
 * - Gender(MON_MALE | MON_FEMALE)
 * - Nature(nature)
 * - Ability(ability)
 * - Level(level)
 * - MaxHP(n), HP(n), Attack(n), Defense(n), SpAttack(n), SpDefense(n)
 * - Speed(n)
 * - Item(item)
 * - Moves(moves...)
 * - Friendship(friendship)
 * - Status1(status1)
 * For example to create a Wobbuffet that is poisoned:
 *     PLAYER(SPECIES_WOBBUFFET) { Status1(STATUS1_POISON); }
 * Note if Speed is specified for any Pokémon then it must be specified
 * for all Pokémon.
 * Note if Moves is specified then MOVE will not automatically add moves
 * to the moveset.
 *
 * AI_FLAGS
 * Specifies which AI flags are run during the test. Has use only for AI tests.
 * The most common combination is  AI_FLAGS(AI_FLAG_CHECK_BAD_MOVE | AI_FLAG_CHECK_VIABILITY | AI_FLAG_TRY_TO_FAINT)
 * which is the general 'smart' AI.
 *
 * WHEN
 * Contains the choices that battlers make during the battle.
 *
 * TURN
 * Groups the choices made by the battlers on a single turn. If Speeds
 * have not been explicitly specified then the order of the MOVEs in the
 * TURN will be used to infer the Speeds of the Pokémon, e.g.:
 *     // player's speed will be greater than opponent's speed.
 *     TURN { MOVE(player, MOVE_SPLASH); MOVE(opponent, MOVE_SPLASH); }
 *     // opponent's speed will be greater than player's speed.
 *     TURN { MOVE(opponent, MOVE_SPLASH); MOVE(player, MOVE_SPLASH); }
 * The inference process is naive, if your test contains anything that
 * modifies the speed of a battler you should specify them explicitly.
 *
 * MOVE(battler, move | moveSlot:, [gimmick:], [hit:], [criticalHit:], [target:], [allowed:], [WITH_RNG(tag, value])
 * Used when the battler chooses Fight. Either the move ID or move slot
 * must be specified. gimmick: GIMMICK_MEGA causes the battler to Mega
 * Evolve if able, hit: FALSE causes the move to miss, criticalHit: TRUE
 * causes the move to land a critical hit, target: is used in double
 * battles to choose the target (when necessary), and allowed: FALSE is
 * used to reject an illegal move e.g. a Disabled one. WITH_RNG allows
 * the move to specify an explicit outcome for an RNG tag.
 *     MOVE(playerLeft, MOVE_TACKLE, target: opponentRight);
 * If the battler does not have an explicit Moves specified the moveset
 * will be populated based on the MOVEs it uses.
 *
 * FORCED_MOVE(battler)
 * Used when the battler chooses Fight and then their move is chosen for
 * them, e.g. when affected by Encore.
 *     FORCED_MOVE(player);
 *
 * SWITCH(battler, partyIndex)
 * Used when the battler chooses Switch.
 *     SWITCH(player, 1);
 *
 * SKIP_TURN(battler)
 * Used when the battler cannot choose an action, e.g. when locked into
 * Thrash.
 *     SKIP_TURN(player);
 *
 * SEND_OUT(battler, partyIndex)
 * Used when the battler chooses to switch to another Pokémon but not
 * via Switch, e.g. after fainting or due to a U-turn.
 *     SEND_OUT(player, 1);
 *
 * USE_ITEM(battler, itemId, [partyIndex:], [move:])
 * Used when the battler chooses to use an item from the Bag. The item
 * ID must be specified, and party index and move slot if applicable, e.g:
 *      USE_ITEM(player, ITEM_X_ATTACK);
 *      USE_ITEM(player, ITEM_POTION, partyIndex: 0);
 *      USE_ITEM(player, ITEM_LEPPA_BERRY, partyIndex: 0, move: MOVE_TACKLE);
 *
 * SCENE
 * Contains an abridged description of the UI during the THEN. The order
 * of the description must match too, e.g.
 *     // ABILITY_POPUP followed by a MESSAGE
 *     ABILITY_POPUP(player, ABILITY_STURDY);
 *     MESSAGE("Geodude was protected by Sturdy!");
 *
 * ABILITY_POPUP(battler, [ability])
 * Causes the test to fail if the battler's ability pop-up is not shown.
 * If specified, ability is the ability shown in the pop-up.
 *     ABILITY_POPUP(opponent, ABILITY_MOLD_BREAKER);
 *
 * ANIMATION(type, animId, [battler], [target:])
 * Causes the test to fail if the animation does not play. A common use
 * of this command is to check if a move was successful, e.g.:
 *     ANIMATION(ANIM_TYPE_MOVE, MOVE_TACKLE, player);
 * target can only be specified for ANIM_TYPE_MOVE.
 *
 * EXPERIENCE_BAR(battler, [exp: | captureGainedExp:])
 * If exp: is used, causes the test to fail if that amount of
 * experience is not gained, e.g.:
 *     EXPERIENCE_BAR(player, exp: 0);
 * If captureGainedExp: is used, causes the test to fail if
 * the Experience bar does not change, and then writes that change to the
 * pointer, e.g.:
 *     u32 exp;
 *     EXPERIENCE_BAR(player, captureGainedExp: &exp);
 * If none of the above are used, causes the test to fail if the Exp
 * does not change at all.
 * Please note that due to nature of tests, this command
 * is only usable in WILD_BATTLE_TEST and will fail elsewhere.
 *
 * HP_BAR(battler, [damage: | hp: | captureDamage: | captureHP:])
 * If hp: or damage: are used, causes the test to fail if that amount of
 * damage is not dealt, e.g.:
 *     HP_BAR(player, hp: 0);
 * If captureDamage: or captureHP: are used, causes the test to fail if
 * the HP bar does not change, and then writes that change to the
 * pointer, e.g.:
 *     s16 damage;
 *     HP_BAR(player, captureDamage: &damage);
 * If none of the above are used, causes the test to fail if the HP
 * does not change at all.
 *
 * MESSAGE(pattern)
 * Causes the test to fail if the message in pattern is not displayed.
 * Spaces in pattern match newlines (\n, \l, and \p) in the message.
 * Often used to check that a battler took its turn but it failed, e.g.:
 *     MESSAGE("Wobbuffet used Dream Eater!");
 *     MESSAGE("Foe Wobbuffet wasn't affected!");
 *
 * STATUS_ICON(battler, status1 | none: | sleep: | poison: | burn: | freeze: | paralysis:, badPoison:)
 * Causes the test to fail if the battler's status is not changed to the
 * specified status.
 *     STATUS_ICON(player, badPoison: TRUE);
 * If the expected status icon is parametrized the corresponding STATUS1
 * constant can be provided, e.g.:
 *     u32 status1;
 *     PARAMETRIZE { status1 = STATUS1_NONE; }
 *     PARAMETRIZE { status1 = STATUS1_BURN; }
 *     ...
 *     STATUS_ICON(player, status1);
 *
 * NOT
 * Causes the test to fail if the SCENE command succeeds before the
 * following command succeeds.
 *     // Our Wobbuffet does not Celebrate before the foe's.
 *     NOT MESSAGE("Wobbuffet used Celebrate!");
 *     MESSAGE("Foe Wobbuffet used Celebrate!");
 * WARNING: NOT is an alias of NONE_OF, so it behaves surprisingly when
 *          applied to multiple commands wrapped in braces.
 *
 * ONE_OF
 * Causes the test to fail unless one of the SCENE commands succeeds.
 *     ONE_OF {
 *         MESSAGE("Wobbuffet used Celebrate!");
 *         MESSAGE("Wobbuffet is paralyzed! It can't move!");
 *     }
 *
 * NONE_OF
 * Causes the test to fail if one of the SCENE commands succeeds before
 * the command after the NONE_OF succeeds.
 *     // Our Wobbuffet does not move before the foe's.
 *     NONE_OF {
 *         MESSAGE("Wobbuffet used Celebrate!");
 *         MESSAGE("Wobbuffet is paralyzed! It can't move!");
 *     }
 *     MESSAGE("Foe Wobbuffet used Celebrate!");
 *
 * PLAYER_PARTY and OPPONENT_PARTY
 * Refer to the party members defined in GIVEN, e.g.:
 *     s32 maxHP = GetMonData(&OPPONENT_PARTY[0], MON_DATA_MAX_HP);
 *     HP_BAR(opponent, damage: maxHP / 2);
 *
 * THEN
 * Contains code to run after the battle has finished. If the test is
 * PARAMETRIZEd then EXPECTs between the results should go here. Is also
 * occasionally used to check the internal battle state when checking
 * the behavior via a SCENE is too difficult, verbose, or error-prone.
 *
 * FINALLY
 * Contains checks to run after all PARAMETERIZEs have run. Prefer to
 * write your checks in THEN where possible, because a failure in THEN
 * will be tagged with which parameter it corresponds to.
 *
 * EXPECT(cond)
 * Causes the test to fail if cond is false.
 *
 * EXPECT_EQ(a, b), EXPECT_NE(a, b), EXPECT_LT(a, b), EXPECT_LE(a, b), EXPECT_GT(a, b), EXPECT_GE(a, b)
 * Causes the test to fail if a and b compare incorrectly, e.g.
 *     EXPECT_EQ(results[0].damage, results[1].damage);
 *
 * EXPECT_MUL_EQ(a, m, b)
 * Causes the test to fail if a*m != b (within a threshold), e.g.
 *     // Expect results[0].damage * 1.5 == results[1].damage.
 *     EXPECT_EQ(results[0].damage, Q_4_12(1.5), results[1].damage); */
