How to retrieve the method parameters of a mock-injected method, which is called by the function being tested?
问题
public class SearchServiceTest {
@InjectMocks
SearchService searchService;
@Mock
Mapvalues mapvalues;
@Before
public void setUp() throws FileNotFoundException {
MockitoAnnotations.initMocks(this);
Map<String, Integer> map = new HashMap<>();
File fp = ResourceUtils.getFile("classpath:test.txt");
Scanner sc = new Scanner(fp);
while (sc.hasNextLine()) {
String line = sc.nextLine();
map.put(line, 300);
}
// Rest of your setup code...
}
@Test
public void testDoSomething() {
// Modify this part to capture the key passed to the method
ArgumentCaptor<String> keyCaptor = ArgumentCaptor.forClass(String.class);
when(mapvalues.getval(keyCaptor.capture())).thenReturn(300);
searchService.doSomething();
// Retrieve the captured key
String capturedKey = keyCaptor.getValue();
int retrievedValue = map.get(capturedKey); // Use the captured key to get the value from the map
// Assertions or verifications...
}
}
Note: The code provided includes modifications to capture the key parameter passed to mapvalues.getval() using Mockito's ArgumentCaptor and then retrieve the corresponding value from the map. The comments in the code highlight the relevant changes. Please ensure that you import the necessary classes and interfaces for the code to work properly.
英文:
public class SearchServiceTest
{
@InjectMocks
SearchService searchService;
@Mock
Mapvalues mapvalues;
@Before
public void setUp() throws FileNotFoundException
{
MockitoAnnotations.initMocks(this);
Map<String, Integer> map = new Hashmap<>();
File fp = ResourceUtils.getFile("classpath:test.txt");
Scanner sc = new Scanner(fp);
while (sc.hasNextLine())
{
String line = sc.nextLine();
map.put(line, 300);
}
}
@Test
public void testDoSomething()
{
searchService.doSomething();
//so basically this doSomething() method calls the method mapvalues.getval(String key),
//but instead I want to perform map.get(key) when the method is called.
}
}
So the doSomething() method calls the mapvalues.getval(String key) method, which returns an integer value, but I want to pass the key value to map.get(key) when the method is called. How do I retrieve that parameter?

当(mapvalues.get(any())).thenAnswer((Answer
String key = invocation.getArgument(0);
});
英文:
when(mapvalues.get(any())).thenAnswer((Answer<String>) invocation -> {
String key = invocation.getArgument(0);
});

你正在测试 searchService.doSomething();
我将假设这个方法的主体包含语句 mapvalues.getval("KEY-VALUE");
在进行测试调用之前，在你的设置中，对你期望被调用的方法进行存根处理：
when(mapvalues.getval(any())).then(new Answer<Integer>() {
@Override
public Integer answer(InvocationOnMock invocation) throws Throwable {
return map.get(invocation.getArgument(0, String.class));
}
});
在测试调用之后，你希望确保期望的方法已使用预期的参数值进行了调用：
verify(mapvalues).getval(eq("KEY-VALUE"));
英文:
You're testing searchService.doSomething();
I will assume that the body of this method contains the statement mapvalues.getval("KEY-VALUE");
Before doing the test call, in your setup, stub the method that you expect to be invoked
when(mapvalues.getval(any())).then(new Answer<Integer>() {
@Override
public Integer answer(InvocationOnMock invocation) throws Throwable {
return map.get(invocation.getArgument(0, String.class));
}
});
After the test call, you want to make sure the wanted method has been invoked with the expected parameter values.
verify(mapvalues).getval(eq("KEY-VALUE"));
