如何模拟kotlin对象进行单元测试

testImplementation 'org.mockito:mockito-core:3.12.4'

class MyClass {
    fun add(a: Int, b: Int): Int {
        return a + b
    }
}

import org.mockito.Mock
import org.mockito.InjectMocks
import org.mockito.MockitoAnnotations

class MyClassTest {
    @Mock
    lateinit var myDependency: MyDependency

    @InjectMocks
    lateinit var myClass: MyClass

    @Before
    fun setup() {
        MockitoAnnotations.openMocks(this)
    }

    @Test
    fun testAdd() {
        // 模拟myDependency的行为
        Mockito.`when`(myDependency.getValue()).thenReturn(5)

        val result = myClass.add(2, 3)

        assertEquals(8, result)
    }
}
