我正在嘗試對(duì)調(diào)用 Thread.sleep 的方法進(jìn)行單元測(cè)試。public Boolean waitForUpscale(){ String res = someObject.upTheResources(); Thread.sleep(20000); Boolean status = someObject.checkForStatus(); return status;}在測(cè)試這個(gè)時(shí)，測(cè)試也會(huì)休眠，因?yàn)門hread.sleep我必須在測(cè)試時(shí)避免測(cè)試休眠。更新：我添加了這個(gè)測(cè)試：@Test public void downscaleTest() throws Exception { when(someservice.downScaleResources()).thenReturn("DONE"); PowerMockito.mockStatic(Thread.class); doNothing().when(Thread.class, "sleep", anyLong()); Boolean res = Whitebox.invokeMethod(myController, "downscaleALL"); assertTrue(res); }當(dāng)我調(diào)試它時(shí)它有效。但是當(dāng)我正常運(yùn)行測(cè)試時(shí)，它失敗并給出以下異常：0 matchers expected, 1 recorded:-> at com.mypackage.controller.MyController.downscaleALL(MyControllerTest.java:265)This exception may occur if matchers are combined with raw values: //incorrect: someMethod(anyObject(), "raw String");When using matchers, all arguments have to be provided by matchers.For example: //correct: someMethod(anyObject(), eq("String by matcher"));For more info see javadoc for Matchers class.添加 downScaleAll 方法private Boolean downscaleALL() { try { String downScaleResources = someservice.downScaleResources(); if (downScaleResources.equals("DONE")) { Thread.sleep(20000); // 20s log.info("DOWNSCALING THE RESOURCES NOW"); return true; } return false; } catch (Exception e) { log.error("Error while downscaling the resources"); log.error(e.toString()); return false; }}

您應(yīng)該只模擬您擁有的類型，因此，如果您想模擬對(duì) 的調(diào)用Thread.sleep()，您應(yīng)該將其提取到您擁有的類型（例如ThreadSleeper）中，因此可以模擬。更好的是，如果可以的話，重寫以避免睡眠。睡眠通常是一種代碼氣味（偷工減料）。

你不應(yīng)該嘲笑你不擁有的類型。但如果你還必須這樣做，你可以這樣做
@RunWith(PowerMockRunner.class)
@PrepareForTest({<ClassWherewaitForUpscaleFunctionisLocated>.class, Thread.class})
public class Mytest {
? ? @Test
? ? public void testStaticVoid() throws Exception {
? ? ? ? PowerMockito.mockStatic(Thread.class);
? ? ? ? doNothing().when(Thread.class, "sleep", anyLong());
? ? ? ? .........
? ? }
}
