我正在尝试在GORM中正确定义树结构并遇到问题。
我有一个域对象:
class Navigation {
Navigation parent
List children;
String name;
static belongsTo = [parent: Navigation]
static hasMany = [children: Navigation]
static constraints = {
parent(nullable: true);
}
}
和测试:
void testTree() {
Navigation root = new Navigation(name:"root");
Navigation top1 = new Navigation(name:"home");
Navigation top2 = new Navigation(name:"services");
root.addToChildren(top1).addToChildren(top2).save(flush: true);
Navigation s1 = new Navigation(name:"plumbing")
Navigation s2 = new Navigation(name:"baking")
top2.addToChildren(s1).addToChildren(s2).save(flush: true);
Navigation t = Navigation.findByName("root")
assert t.children.size() == 2
}
如果我运行此测试,我会收到此错误:
org.codehaus.groovy.runtime.InvokerInvocationException: groovy.lang.MissingMethodException: No signature of method: grails.Navigation.addToChildren() is applicable for argument types: (grails.Navigation) values: [grails.Navigation : null]
如果我将该测试的内容放入boostrap,我不得到该错误,应用程序启动,除了导航表为空
我该怎么做才能解决这个问题?

您需要模拟导航域,以便在单元测试中使用GORM方法。
将其添加到测试用例的顶部:
mockDomain(Navigation)
