我正在Jetpack Compose应用程序上尝试一个相当简单的UI测试。
SUT是一个登录屏幕，包含两个用于电子邮件和密码的字段以及一个用于密码重置的链接。
当点击重置链接时，密码字段将隐藏，电子邮件字段将保留。
以下是整个测试类：
@HiltAndroidTest
class LoginScreenTests {
@get:Rule(order = 0)
val hiltRule = HiltAndroidRule(this)
@get:Rule(order = 1)
val composeRule = createAndroidComposeRule<MainActivity>()
@Before
fun setup() {
hiltRule.inject()
composeRule.setContent {
MyTheme {
LoginScreen()
}
}
}
@Test
fun onStart_shouldDisplayEmailAndPass() {
composeRule.onNodeWithTag("email").assertIsDisplayed()
composeRule.onNodeWithTag("password").assertIsDisplayed()
}
@Test
fun resetMode_shouldHidePass() {
composeRule.onNodeWithTag("resetPassword").performClick()
composeRule.onNodeWithTag("email").assertIsDisplayed()
composeRule.onNodeWithTag("password").assertDoesNotExist()
}
}
当我单独运行它们时，两个测试都通过。当我运行类时，第二个测试失败。
正如我所注意到的，甚至在测试函数中也没有发生故障。它中断了设置功能，但我无法确定中断的原因。我可以在hiltRule.inject和composeRule.setContent上设置断点，断点确实命中，但即使被断点停止，进程也会被终止。
还有一个失败测试的日志，上面写着关于注销输入通道的内容。

您需要在类中添加此行
@RunWith(AndroidJUnit4::class)
并且这些行对于代码来说是不必要的
@HiltAndroidTest
@get:Rule(order = 0)
val hiltRule = HiltAndroidRule(this)
hiltRule.inject()
您的代码应该看起来像
@RunWith(AndroidJUnit4::class)
