我们已通过springframework.test.context.junit4
创建了功能测试。
以下是测试用例之一:
测试类
@Test
public void testAuthorizedPut() throws Exception {
ThreadContext.bind(subject);
when(subject.isPermitted(getPlural() + ":put")).thenReturn(true);
when(subject.isPermitted(getPlural() + ":get")).thenReturn(true);
assertThat(adminTemplate().exchange(getTestHost() + "/api/1/" + getPlural() + "/45454-67567d-f5224666a9", HttpMethod.PUT, new HttpEntity<Object>(getInstance(),getStandardHeaders()),entityClass).getBody(), equalTo(getInstance()));
}
当代码移动到用于模拟的资源类时。与上述测试代码一样,将转移到资源的PUT请求:
MyResource Class
@ApiOperation(value = "Update MyResource definition", notes = "Enter the id of the MyResource definition, returns updated MyResource definition", response = MyResource.class)
@Path("/{id}")
@PUT
@Timed
@Override
public MyResource update(@PathParam("id") String id, MyResource newInstance) {
return super.update(id, newInstance);
}
当我们运行上面写的测试 testAuthorizedPut 时,它会抛出以下错误:
java.lang.AssertionError:
Expected: <MyResource(id=null, metadataTemplate=null, name=null, shortLabel=null, description=null, embedInObject=false, optional=false, type=null, possibleValues=null)>
but: was null

但是当我写资源类PUT时,意味着返回newInstance单独解决上面的错误:
public MyResource update(@PathParam("id") String id, MyResource newInstance) {
super.update(id, newInstance);
return newInstance;
}
那么返回newInstance与超级调用或单独调用有什么区别呢。如果没有上述更改,如何解决此错误?
答案 0 :(得分:1)
来自继承的Update()方法的代码将是apreciated。 并且,在一种情况下,您从方法返回接收的对象,在第二种情况下,您从同一方法中的方法参数返回对象。 你的问题的答案在于super.update()blackBox。
就我所知,它可能是
MyResource update(){
return null;
}
这可以解释输出。你应该检查为什么super.update返回null。
