JUnit5 vs Spock

JUnit5(Java)

public void 충전_트랜잭션이_성공한다() {
    // Given
    ChargeTransactionRequest request = new ChargeTransactionRequest(1L, "orderId", BigDecimal.TEN);

    when(transactionRepository.findTransactionByOrderId(request.getOrderId())).thenReturn(Optional.empty());

    FindWalletResponse findWalletResponse = new FindWalletResponse(1L, 1L, BigDecimal.ZERO, LocalDateTime.now(), LocalDateTime.now());
    when(walletService.findWalletByUserId(1L)).thenReturn(findWalletResponse);

    AddBalanceWalletResponse addBalanceWalletResponse = new AddBalanceWalletResponse(
            1L, 1L, findWalletResponse.getBalance().add(request.getAmount()), LocalDateTime.now(), LocalDateTime.now());
    when(walletService.addBalance(any())).thenReturn(addBalanceWalletResponse);

    // When
    Wallet createdWallet = transactionService.charge(request);

    // Then
    verify(transactionRepository, times(1)).save(any());
    assertNotNull(createdWallet);
    System.out.println(createdWallet);
}

 

Spock(Groovy)

def "충전 트랜잭션이 성공한다."() {
    given:
    ChargeTransactionRequest request = new ChargeTransactionRequest(1L, "orderId", BigDecimal.TEN)

    transactionRepository.findTransactionByOrderId(request.orderId()) >> Optional.empty()

    def findWalletResponse = new FindWalletResponse(1L, 1L, BigDecimal.ZERO, LocalDateTime.now(), LocalDateTime.now())
    walletService.findWalletByUserId(1L) >> findWalletResponse

    def addBalanceWalletResponse = new AddBalanceWalletResponse(
            1L, 1L, findWalletResponse.balance().add(request.amount()), LocalDateTime.now(), LocalDateTime.now()
    )
    walletService.addBalance(_) >> addBalanceWalletResponse

    when:
    def createdWallet = transactionService.charge(request)

    then:
    1 * transactionRepository.save(_)
    createdWallet != null
    println createdWallet
}

 

Spock가 좀 더 가독성 좋은 느낌 ~

자주 써봐야겠다.
