尽管该错误描述性很强,但我无法理解它。 对于行:
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?
最佳答案
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");
关于java - 参数匹配器的使用无效!预期 0 个匹配器,记录 1 个,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/26418376/
