如何在Grails服务类单元测试中模拟静态Map属性

Question

I have a static map in a service class.I am unit testing the method which populates the map. I want to know how to mock the map used in the service class.

SomeService
--------------

class SomeService {
    static Map<Integer,String> tempMap = new HashMap<Integer,String>()
        //This map is used in some other service api
}

OtherService
------------

class OtherService {
    void method1(Integer i, String str) {
        // here it populates the map
        def test = SomeService.tempMap.put(i,str)
        println "After putting : "+test 
    }
}

Unit test case

OtherServiceTests
------------------
class OtherServiceTests {
    void testMethod1() {
        def mockedMap = mockFor(Map)
        SomeService.metaClass.static.tempMap = mockedMap.createMock()
        SomeService.metaClass.static.tempMap.put = {Integer i, String str -> "Testing"} // how to mock??
    }
}

When I run the test case it is invoking the real map instead of making use of the mocked "put" api, which is returning null instead of "testing" I tried couple of ways to mock it but still no luck. How to mock Map api which is a static property of a service class?

对于嘲笑，您可以尝试

SomeService.tempMap.getClass().metaClass.put = {Integer i, String str -> "Testing"}
