Question

我需要为测试初始化两个活动。我确实是这样：

@RunWith(AndroidJUnit4::class)
@SmallTest
class AddTraderActivityTest {

    @get:Rule
    var addTraderActivity: IntentsTestRule<AddTraderActivity> = IntentsTestRule(AddTraderActivity::class.java)

    @get:Rule
    var traderActivity: IntentsTestRule<TradersActivity> = IntentsTestRule(TradersActivity::class.java)

    @Test
    fun toolBarHeight() {
        onView(withId(R.id.toolBar)).check(matches(withHeightResId(R.dimen.tool_bar_height)))
    }

但是当我运行测试时，我得到了错误：

我会尝试切换到ActivityTestRule 并自己制作IntentsTestRule的魔力

@RunWith(AndroidJUnit4::class)
@SmallTest
class AddTraderActivityTest {

    @get:Rule
    var addTraderActivity: ActivityTestRule <AddTraderActivity> = IntentsTestRule(AddTraderActivity::class.java)

    @get:Rule
    var traderActivity: ActivityTestRule <TradersActivity> = IntentsTestRule(TradersActivity::class.java)

    @Before
    fun setUp() {
        Intents.init()
    }

    @After
    fun cleanUp() {
        Intents.release()
    }
    ...

java.lang.IllegalStateException：#init连续两次被调用。确保在每次#init之后调用#release
