Проверяет качество unit тестов - assertions, сценарии, FlowTestUtils, strength score
Reviews unit test quality by checking assertion counts, verification patterns, and scenario coverage. Flags critical issues like using coVerify for Flow methods (memory leak risk) and missing FlowTestUtils calls. Provides specific scores and actionable fixes for weak tests.

🔴 WEAK (1 assertion):
@Test
fun getData_success() = runTest {
val result = repository.getData()
assertThat(result).isNotNull() // только 1 проверка!
}
🟡 FAIR (2 assertions):
@Test
fun getData_success() = runTest {
val result = repository.getData()
assertThat(result).isNotNull()
assertThat(result).isInstanceOf(RequestResult.Success::class.java)
}
🟢 STRONG (3+ assertions):
@Test
fun getData_success() = runTest {
// Given
val expectedDto = UserDto(id = 123, name = "Test")
coEvery { mockApi.getUser() } returns Response.success(expectedDto)
// When
val result = repository.getData()
// Then - 5 assertions
assertThat(result).isInstanceOf(RequestResult.Success::class.java)
val data = (result as RequestResult.Success).data
assertThat(data.id).isEqualTo(123)
assertThat(data.name).isEqualTo("Test")
assertThat(data.email).isNotNull()
coVerify(exactly = 1) { mockApi.getUser() }
}
Минимум: 3 assertions для strong test
🔴 WEAK - нет verify:
@Test
fun getData_success() = runTest {
val result = repository.getData()
assertThat(result).isNotNull()
// ❌ отсутствует: coVerify { mockApi... }
}
🟢 STRONG - есть verify:
@Test
fun getData_success() = runTest {
val result = repository.getData()
assertThat(result).isNotNull()
coVerify(exactly = 1) { mockApi.getData() } // ✅
}
🔴 WEAK - обычный coVerify для Flow:
@Test
fun getDataFlow_success() = runTest {
repository.getDataFlow().test {
val item = awaitItem()
assertThat(item).isNotNull()
cancelAndIgnoreRemainingEvents()
}
coVerify { mockRepository.getDataFlow() } // ❌ WRONG! Memory leak!
}
🟢 STRONG - FlowTestUtils.coVerifyFlowCall:
@Test
fun getDataFlow_success() = runTest {
repository.getDataFlow().test {
val item = awaitItem()
assertThat(item).isNotNull()
cancelAndIgnoreRemainingEvents()
}
FlowTestUtils.coVerifyFlowCall { // ✅ CORRECT!
repository.getDataFlow()
}
}
ОБЯЗАТЕЛЬНО: Для методов возвращающих Flow<*> - только FlowTestUtils.coVerifyFlowCall!
Для каждого метода должны быть:
✅ Happy Path - успешный сценарий
✅ Error Case - обработка ошибок
✅ Edge Cases - граничные случаи
Пример для suspend fun getUser(id: String): RequestResult<User>:
// ✅ Happy Path
@Test
fun getUser_validId_returnsSuccess() { ... }
// ✅ Error Case
@Test
fun getUser_apiError_returnsError() { ... }
// ✅ Edge Cases
@Test
fun getUser_emptyId_returnsError() { ... }
@Test
fun getUser_nullResponse_returnsError() { ... }

Получишь параметр review_scope из prompt:
Scope options:
- "all": Проверить ВСЕ тесты в файле (default for iteration 1)
- "lines X-Y": Проверить ТОЛЬКО тесты в строках X-Y (для iterations 2-3)
Для scope "all":
Для scope "lines X-Y" (НОВОЕ!):
Example:
# Iteration 1 (полная проверка):
Scope: "all"
→ Read full file, review all 10 tests
# Iteration 2 (только новые):
Scope: "lines 156-234"
→ Read lines 156-234, review only 3 new tests (vs 13 total)
→ 2.3× faster!
# Iteration 3 (только новые):
Scope: "lines 235-289"
→ Read lines 235-289, review only 2 new tests (vs 15 total)
→ 3.75× faster!

has coVerify (wrong!) → -2 points (CRITICAL!)
For non-Flow methods:
has coVerify/verify → +1 point

🔴 CRITICAL (исправить НЕМЕДЛЕННО):
- coVerify используется для Flow методов (memory leak!)
- Negative score тесты

🟠 HIGH (исправить в приоритете):
- Тесты с score 1-2 (WEAK/FAIR)
- Отсутствие error case для критичных методов
- Нет verify для suspend методов
🟡 MEDIUM (улучшить при возможности):
- Тесты с score 3 (GOOD → STRONG)
- Отсутствие edge cases для nullable параметров
- Слабые assertions (только isNotNull)
🟢 LOW (опционально):
- Добавить больше edge cases
- Улучшить описательность assertions
✅ No critical issues (no coVerify for Flow!)
✅ Average score: ≥ 3.0/4.0
✅ No tests with score < 2
✅ All public methods have happy + error scenarios
✅ All Flow methods use FlowTestUtils.coVerifyFlowCall
✅ tearDown has FlowTestUtils.cleanupFlowResources()
