How to Mock Request Headers in Java

This is the sample code of what I have written

    String bearerToken="Bearer "+ token; 
    HttpClient client = HttpClientBuilder.create().build(); 
    request.addHeader("Authorization",bearerToken); 
    request.addHeader("cache-control", "no-cache"); 
    HttpResponse response=client.execute(request); 
    System.out.println("Response Code:" + response.getStatusLine().getStatusCode());

How can I mock these request headers in java? How do I mock Authorization and response?.

In your unit test class you need to mock client:

@Mock
private HttpClient client;

Then you tell mockito in @Before method to actually create your mocks by

MockitoAnnotations.initMocks(YourTestClass);

Then in your test method, you can mock what execute() method should return:

Mockito.when(client.execute(any()/* or wahtever you want here */)).thenReturn(your json object);

Mocking your HttpClient is preferred more because there may be some times when if you make an actual call to the rest API after mocking your headers the API may return unwanted response[when the service is down or restarting].

But if you still want to mock a private field you can do it using

ReflectionUtils.setField()
