【问题描述】：

我正在使用 Grails 3.1.9，并且正在尝试了解如何测试服务。这是我的实体：

class Flight {
    String number
    Plane plane
    Airport origin
    Airport destination
    LocalDate departureDate
    LocalTime departureTime
    LocalDate arrivalDate
    LocalTime arrivalTime
    BigDecimal ticketPrice
    boolean cancelled

    static hasMany = [
        bookings: Booking
    ]

    static constraints = {
    }
}

这是我的服务：

@Transactional
class FlightService {
    List<Flight> search(Airport from, Airport to, LocalDate on) {
        return Flight.findAllByOriginAndDestinationAndDepartureDate(from, to, on)
    }
}

这是我的测试：

@TestFor(FlightService)
@Mock([Flight])
class FlightServiceSpec extends Specification {

    def setup() {
    }

    def cleanup() {
    }

    void "test search"() {
        when:
            def sfo = new Airport(code: 'SFO', city: 'San Francisco', countryCode: 'US', timeZone: ZoneId.of("America/Los_Angeles"))
            def bru = new Airport(code: 'BRU', city: 'Brussels', countryCode: 'BE', timeZone: ZoneId.of("Europe/Brussels"))
            service.search(bru, sfo, LocalDate.of(2016, 8, 31))
        then:
            1 * Flight.findAllByOriginAndDestinationAndDepartureDate(*_)
    }
}

但是当我运行 grails test-app 时，报告中出现以下异常：

org.springframework.dao.InvalidDataAccessResourceUsageException: Cannot query [com.epseelon.atr.Flight] on non-existent property: departureDate

我不明白，因为 Flight 实体上有一个离开日期属性。

【问题讨论】：

您使用哪个数据库进行测试？ H2 还是 MySQL？
我正在使用 H2 进行测试
您是否尝试过在测试时也将数据库更改为 MySQL？

【解决方案1】：

将此添加到您的规范中以启用 joda 时间单元测试支持

def setupSpec() {
    SimpleMapJodaTimeMarshaller.initialize();
}
