Grails - 在域类问题上测试自定义验证器

Question

我正在学习Grails的Grails - 由Jason Rudolph的书开始.我的域类看起来像这样:

class Race {

  String name;
  Date startDateTime
  String city
  String state
  Float distance
  Float cost
  Integer maxRunners = 10000

  static hasMany = [registrations: Registration]

  static constraints = {
    name(maxSize: 50, blank: false)
    startDateTime(validator: {
      return it > new Date()
    })
    city(maxSize: 30, blank: false)
    state(inList: ['GA', 'NC', 'SC', 'VA'], blank: false)
    distance(min: 3.1f, max: 100f)
    cost(min: 0f, max: 999.99f)
  }

  String toString() { "${this.name} : ${this.city}, ${this.state}" }
}

我想测试startDateTime字段的自定义验证.测试看起来像这样:

class RaceTests extends GrailsUnitTestCase {
  protected void setUp() {
    super.setUp()
  }

  protected void tearDown() {
    super.tearDown()
  }

  void testCustomDateValidation() {
    def race = new Race()
    race.startDateTime = null
    assertFalse(race.validate())
  }
}

测试看起来类似于我前面提到的那本书.但我得到了

groovy.lang.MissingMethodException: No signature of method: racetrack.Race.validate() is applicable for argument types: () values: []

我被困住了,没有找到任何解决方案:/任何帮助将不胜感激.

Answer 1

你错过了mockForConstraintsTests()调用.常见的模式是在setUp()中执行此操作

protected void setUp() {
  super.setUp()
  mockForConstraintsTests(Race)    
}
