QUESTION

Can anyone suggest a mockito Test for this code?

Asked 2021-Nov-16 at 06:47

This function tries to retrieve the topic of the GitHub repository name using the GitHub API: https://api.github.com/repos/flutter/flutter/topics

public List<String> getTopics(SearchRepository searchRepository){
        GitHubRequest request = new GitHubRequest();
        List<String> topic_list = new ArrayList<>();
        try {

            String url =  searchRepository.getUrl().split("//")[1].split("github.com")[1];

            request.setUri("/repos"+ url + "/topics");
            String result = new BufferedReader(new InputStreamReader(gitHubClient.getStream(request)))
                    .lines().collect(Collectors.joining("\n"));
            JSONObject jsonObject = new JSONObject(result);
            topic_list = Arrays.stream(jsonObject.get("names").toString().replace("[", "").replace("]", "").split(",")).collect(Collectors.toList());
        } catch (IOException e) {
            e.printStackTrace();
        }
        return topic_list;
    }

The url returned before string to list conversion is :https://github.com/repouser/reponame

SearchRepository is the v2 model class of Repository from the package: SearchRepositroy As per the earlier suggestions from this wonderful community answers (though the question is now edited, it remains yet relevant) I created the mock test to test the above function as below:

    @Test
    public void getTopicsTest() throws IOException{
        SearchRepository mocksearchRepository = mock(SearchRepository.class);
        GitHubClient mockClient = mock(GitHubClient.class);
        GitHubRequest mockRequest = mock(GitHubRequest.class);
        when(mocksearchRepository.getUrl()).thenReturn("https://github.com/mockuser/mockrepo");
        when(mocksearchRepository.getName()).thenReturn("mockrepo");
        when(mocksearchRepository.getOwner()).thenReturn("mockuser");
        //when(mockRequest.setUri((String) any())).thenReturn(mockRequest.setUri("/repo/mockuser/mockrepo/topics"));
        //The format of the return form is: https://github.com/CyC2018/CS-Notes
        when(mockClient.getStream(any())).thenReturn(topicInputStream());
        //SearchRepository querySearch = new SearchRepository("mockuser","mockrepo");
        List<String> topics = githubServiceMock.getTopics(mocksearchRepository);
        System.out.println(topics);
    }

    private InputStream topicInputStream() {
        String mockTopics = "{" +
                "topic1\": [" +
                "topic2\"," +
                "topic3\"," +
                "skia" +
                "]" +
                "}";
        InputStream stream = new ByteArrayInputStream(mockTopics.getBytes(StandardCharsets.UTF_8));
        System.out.println(stream);
        return stream;
    }

However, I get the 404 internal server error Exception due to the request.setUri(Uri(String)) in the function. Please suggest where I am going wrong.

You can mock repositoryService and gitHubClient to test various scenarios.

You can provide a package-level setter for these fields. It is a great idea to annotate it with Guava VisibleForTesting annotation.

Then you need to set mocks before the actual test on the instance.

Pseudocode for mocking

// First, we mock repository so we can return it from service
Repository repositoryMock = mock(Repository.class);
when(repository.getUrl()).thenReturn("https://...."); // You can return a URL or String, according to the mocked method's return type

// Then, we mock RepositoryService as well
RepositoryService repositoryServiceMock = mock(RepositoryService.class);
when(repositoryServiceMock.getRepository(anyString(), anyString()).thenReturn(repositoryMock);

// We mock gitHubService similarly
...

// After setting mock on the instance, we call the method and see if the results are expected
List<String> topics = getTopics("...", "...");

assertEquals(topics, ...);

// You can also assert interaction related things
verify(repositoryService).getRepository("a", "b"); // This is OK only if the service is called with "a" and "b" arguments
