grails - 为什么域类在同一个GroovyTestCase的两种不同方法中表现不同？

Question

我有一个Grails集成测试，它使用两种测试方法扩展了 GroovyTestCase 。第一种方法执行成功，但是第二种方法失败，并带有groovy.lang.MissingMethodException:

Failure: testMapBudgetFailure(com.ross.budget.BudgetServiceTests)
groovy.lang.MissingMethodException: No signature of method:
com.ross.budget.Budget.save() is applicable for argument types: () values: [] Possible solutions: save(), save(boolean), save(java.util.Map), wait(), last(), any()
at com.ross.budget.BudgetServiceTests.testMapBudgetFailure(BudgetServiceTests.groovy:45)

即使第一个方法中调用的b.save()完全相同。如果我评论第一种方法，第二项测试将按预期运行。 为什么两种测试方法的行为不同？

全类列表:

package com.ross.budget



import grails.test.mixin.*
import org.junit.*

/**
 * See the API for {@link grails.test.mixin.services.ServiceUnitTestMixin} for usage instructions
 */
@TestFor(BudgetService)
class BudgetServiceTests extends GroovyTestCase {


    BudgetService budgetService

    void testMapBudgetSuccess() {
        Budget b = new Budget()
        b.month = new Date(2012, 9, 1)
        b.amount = new BigDecimal(10.0)
        b.save()

        Account a = new Account()
        a.name = "Test"
        a.institution = "Test"
        a.description = "Test Account"
        a.save()

        Transaction t = new Transaction()
        t.account = a
        t.postDate = new Date(2012, 9, 5)
        t.amount = 10.0
        t.save()

        boolean result = budgetService.mapTransaction(t)
        assertTrue("Returned failed match.", result)
        assertNotNull("No budget set", t.budget)

    }

    void testMapBudgetFailure() {
        Budget b = new Budget()
        b.month = new Date(112, 5, 1)
        b.amount = new BigDecimal(10.0)
        b.save()

        Account a = new Account()
        a.name = "Test"
        a.institution = "Test"
        a.description = "Test Account"
        a.save()

        Transaction t = new Transaction()
        t.account = a
        t.postDate = new Date(112, 6, 5)
        t.amount = 10.0
        t.save()

        boolean result = budgetService.mapTransaction(t)
        assertFalse("Returned match.", result)
        assertNull("Budget set", t.budget)

    }
}

我知道代码是复制粘贴，并不可爱。这是个人项目的快速测试案例

根据Grails doc，您应该使用@TestFor进行单元测试，或者扩展GroovyTestCase进行集成测试，而不要同时使用两者。
