【问题描述】:
当启动我的 android 应用程序时,首先启动 FirstActivity。
当我单击FirstActivity 上的按钮而不是启动AddTraderActivity。
如果我按下AddTraderActivity 中的“START REQUEST”按钮,那么我会调用:
setResult(RESULT_OK);
finish();
结果AddTraderActivity 被销毁并显示FirstActivity。
不错。
现在我想为 AddTraderActivityTest 编写 Espresso 的测试。
这里测试:
@RunWith(AndroidJUnit4::class)
@SmallTest
class AddTraderActivityTest {
@get:Rule
var addTraderActivity: IntentsTestRule<AddTraderActivity> =
IntentsTestRule(AddTraderActivity::class.java)
@Test
fun toolBarHeight() {
onView(withId(R.id.toolBar))
.check(matches(withHeightResId(R.dimen.tool_bar_height)))
}
@Test
fun buttonStartTextUppercase() {
onView(withId(R.id.startButton))
.check(matches(withTextUppercaseResId(R.string.start)))
}
}
结果当我开始这个测试时,然后只启动AddTraderActivity 并且测试成功通过。
不错。
现在我想为点击按钮“START REQUEST”编写测试
这里测试:
@Test
fun pressButtonStartProgressBarDisplayed() {
onView(withId(R.id.baseTextInputEditText)).perform(typeText("BASE_TEST"))
onView(withId(R.id.quoteTextInputEditText)).perform(typeText("QUOTE_TEST"))
onView(withId(R.id.startButton)).perform(click())
onView(withId(R.id.containerProgressBarLayout)).check(matches(isDisplayed()))
}
当测试运行并按下按钮“START REQUEST”时,我得到下一个错误:
测试于 16:05 开始 ...
$ adb shell am instrument -w -r -e debug false -e class 'com.myproject.AddTraderActivityTest#pressButtonStartProgressBarDisplayed' com.myproject.debug.test/androidx.test.runner.AndroidJUnitRunner

我收到此错误是因为堆栈中没有活动FirstActivity,因为我的测试没有启动它。
所以问题是。
我怎样才能隔离只测试AddTraderActivity?
