问题描述
我刚刚升级了Android Studio 4.1，并在IDE中使所有与模拟Web服务器相关的测试失败，但在终端中却没有。在我升级到4.1之前一切顺利。
我的Okhttp和mockwebserver版本是4.7.2
TestCase.kt
class RepositoryTest : BaseUnittest() {
private lateinit var mockWebServer: MockWebServer
@BeforeEach
override fun setUp() {
mockWebServer = MockWebServer()
mockWebServer.start()
super.setUp()
}
@AfterEach
override fun tearDown() {
super.tearDown()
mockWebServer.shutdown()
}
@Test
fun scenario1() {
...
}
}
IDE中的堆栈跟踪

解决方法
请参见https://github.com/square/okhttp/issues/5759
可能您正在混合依赖版本。检查Intellij项目视图，以确保您在所有okhttp库中使用单个版本
这件事发生在我身上，就像Yuri Schimke回答的那样，我在项目中有两个OkHttp版本（一个是通过改造带来的）。我不得不降级我的OkHttp（不那么痛苦）以匹配改造的Okhttp。排除策略对我也不太有效。
