在grails中使用mockDomain时，如何覆盖方法的逻辑？

Question

我想嘲笑一切像往常一样（mockDomain(Class)），但我想覆盖一个域的方法（beforeDelete是具体的）与定制逻辑只为那一个单元测试。

这怎么能实现？

Answer 1

您可以使用Groovy metaClass覆盖domain类的beforeDelete方法。

域类：

class Person { 
    String name 
    boolean deleted 

    def beforeDelete() { 
    println "Deleting Person ${id}" 
    deleted = true 
    return false 
    } 
} 

单元测试：

void testBeforeDelete() { 
    mockDomain(Person) 
    def p = new Person(name:"test") 
    p.save() 
    assertEquals false, p.deleted 
    p.delete() 
    assertEquals true, p.deleted 
} 

--output从testBeforeDelete--

删除个人从testBeforeDeleteOverr 1

void testBeforeDeleteOverrideBeforeDelete() { 
    mockDomain(Person) 
    Person.metaClass.'static'.beforeDelete = {println 'Do not touch me'} 
    def p = new Person(name:"test") 
    p.save() 
    assertEquals false, p.deleted 
    p.delete() 
    assertEquals true, p.deleted 
} 

--output ideBeforeDelete--

不要碰我

像往常一样用mockDomain模拟域类，然后在该特定的单元测试中模拟beforeDelete关闭与mockFor。例如：

void testDelete() { 
    mockDomain(MyDomainClass) 
    def myDomainClassControl = mockFor(MyDomainClass) 
    myDomainClassControl.demand.beforeDelete(1..1) { -> println "hello world" } 

    ... // test delete 

    myDomainClassControl.verify() 
}
