java - 在 Mockito 中解析

Question

我在 My JUnit 中使用 Mockito 来模拟一些对象。代码工作正常，但是当它到达 setter() 将字符串解析为整数的程度时，我得到 NumberFormatException ，这很好，但我有一个规则，它涵盖了所有行，但是当它得到时对于这个 setter ，它会抛出异常。

场景 1 MUT

if( request.getParameter(UiIntegrationKeyConstants.UI_INTEGRATION_LINE_OF_BUSINESS) != null ) {
        config.setLob((request.getParameter(UiIntegrationKeyConstants.UI_INTEGRATION_LINE_OF_BUSINESS)));
    }

JUnit 用于它

Mockito.when(request.getParameter(Mockito.any(String.class))).thenReturn(UiIntegrationKeyConstants.UI_INTEGRATION_CLIENT_CONTEXT_PATH);

以上规则有效

场景 2 MUT

if( request.getParameter(UiIntegrationKeyConstants.UI_INTEGRATION_CREATED_DAYS) != null ) {
        config.setCreatedDays(Integer.parseInt(request.getParameter(UiIntegrationKeyConstants.UI_INTEGRATION_CREATED_DAYS).toString()));
    }

因此，对于场景 2，我遇到了异常(exception)。我不确定这将如何运作。

如果我做错了什么，请告诉我。

Answer 1

我以下

Mockito.when(request.getParameter(Mockito.any(String.class))).
    thenReturn(UiIntegrationKeyConstants.UI_INTEGRATION_CLIENT_CONTEXT_PATH);

是唯一的when()，那么所有getParameter()调用都将返回该字符串。如果你想指定一个特殊的String，它可以被解析为Integer，你可以使用

Mockito.when(request.getParameter(Mockito.eq("key"))).
    thenReturn("4711");
