I have to fetch path from the property file using Environment interface. In Junits I am not able to mock the Environment Interface. Below is my code. I want something random if I will call the method mentioned. How can I do it?

@Mock
    private Class object;
 @InjectMocks
    Class2 object2;

Mockito.when(object.getFilePath()).thenReturn("Random String");

推荐答案

正如我在评论中所说，你不需要 Mockito，你可以使用 MockEnvironment 类来模拟 Environment 来自 Spring.
您可以通过这种方式设置值:

As said in my comment, you don't need Mockito, you can use MockEnvironment class to mock Environment from Spring.
You can set values in this way :

    MockEnvironment environment = new MockEnvironment();
    environment.setProperty("yourKeyOne", "yourValue1");
    environment.setProperty("yourKeyTwo", "yourValue2");

并且根据您的需要，您可以使用这个环境变量.例如，这里有一个 AnnotationConfigWebApplicationContext 实例:

And according to your need, you can use this environment variable. For example, here is with an AnnotationConfigWebApplicationContext instance :

    AnnotationConfigWebApplicationContext context = new  AnnotationConfigWebApplicationContext();
    context.setEnvironment(environment);
