Java 参数匹配器的使用无效!需要0个匹配器,记录了1个
虽然这个错误很有描述性,但我还是弄不懂。 对于线路:Java 参数匹配器的使用无效!需要0个匹配器,记录了1个,java,unit-testing,junit,mockito,Java,Unit Testing,Junit,Mockito,虽然这个错误很有描述性,但我还是弄不懂。 对于线路: PowerMockito.when( mockStringMessageService.lookupString(Matchers.eq("XYZ"))) .thenReturn(Matchers.eq("XYZ")); 错误是: [junit] Invalid use of argument matchers! [junit] 0 matchers expected, 1 recor
PowerMockito.when(
mockStringMessageService.lookupString(Matchers.eq("XYZ")))
.thenReturn(Matchers.eq("XYZ"));
错误是:
[junit] Invalid use of argument matchers!
[junit] 0 matchers expected, 1 recorded:
[junit] -> at com.amazon.kilvish.types.StatusTableTest.setUp(StatusTableTest.java:61)
[junit]
[junit] This exception may occur if matchers are combined with raw values:
[junit] //incorrect:
[junit] someMethod(anyObject(), "raw String");
[junit] When using matchers, all arguments have to be provided by matchers.
[junit] For example:
[junit] //correct:
[junit] someMethod(anyObject(), eq("String by matcher"));
[junit]
[junit] For more info see javadoc for Matchers class.
为什么需要0个匹配器?您不能在
thenReturn
子句中使用匹配器。只需使用字符串文字即可:
PowerMockito.when(
mockStringMessageService.lookupString(Matchers.eq("XYZ")))
.thenReturn("XYZ");
任何原因,为什么不使用匹配器?
