我开始学习Kotlin和Mockito,所以我编写了一个简单的模块来测试它。一个简单的kotlin类与mockito测试引起MissingMethodInvocationException
AccountData_K.kt:
open class AccountData_K {
var isLogin: Boolean = false
var userName: String? = null
fun changeLogin() : Boolean {
return !isLogin
}
}
AccountDataMockTest_K.kt:
class AccountDataMockTest_K {
@Mock
val accountData = AccountData_K()
@Before
fun setupAccountData() {
MockitoAnnotations.initMocks(this)
}
@Test
fun testNotNull() {
assertNotNull(accountData)
}
@Test
fun testIsLogin() {
val result = accountData.changeLogin()
assertEquals(result, true)
}
@Test
fun testChangeLogin() {
`when`(accountData.changeLogin()).thenReturn(false)
val result = accountData.changeLogin()
assertEquals(result, false)
}
}
当我运行测试,它报告有关testChangeLogin()
方法异常:
org.mockito.exceptions.misusing.MissingMethodInvocationException:
when() requires an argument which has to be 'a method call on a mock'.
For example:
when(mock.getArticles()).thenReturn(articles);
Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.
2. inside when() you don't call method on mock but on some other object.
3. the parent of the mocked class is not public.
It is a limitation of the mock engine.

...
我怀疑为什么该方法不是模拟方法调用...
所以请帮助我,谢谢。
