[英]Invalid use of argument matchers! 0 matchers expected, 1 recorded
雖然錯誤是非常具有描述性的,但我無法理解它。 對於線條:
PowerMockito.when(
mockStringMessageService.lookupString(Matchers.eq("XYZ")))
.thenReturn(Matchers.eq("XYZ"));
錯誤是:
[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.
為什么期望0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:
PowerMockito.when(
mockStringMessageService.lookupString(Matchers.eq("XYZ")))
.thenReturn("XYZ");
