junits中的模拟CosmosClient

Question

我们需要从Azure-CosmosDB - sql api中获取很少的记录以提高覆盖率，我们想要模拟，但是搜索了很多，但没有找到Java。你能在这里做向导吗？

我的DAO类如下所示

private CosmosClient client;

@Autowired
public DAO(CosmosClient client) {
    this.client = client;
}

CosmosDatabase database;
CosmosContainer container;

    private static final String DATABASE = "test-db";
    private static final String CONTAINER = "test-container";

   /**
     * Test method
     */
    public List<TestVO> fetchTestData() {

       // create database
        CosmosDatabaseResponse databaseResponse = client.createDatabaseIfNotExists(DATABASE);
        database = client.getDatabase(databaseResponse.getProperties().getId());

      // create container
        CosmosContainerProperties containerProperties = new CosmosContainerProperties(CONTAINER, "/pkey");
        CosmosContainerResponse containerResponse = database.createContainerIfNotExists(containerProperties,
                throughputProperties);
        container = database.getContainer(containerResponse.getProperties().getId());

           // Form querySpec
            Iterable<FeedResponse<Test>> feedRespIter = container
                    .queryItems(querySpec, queryOptions, Test.class).iterableByPage(continuationToken, pageSize);

            // iterate list of documents to return shipping list
            if (feedRespIter .iterator().hasNext()) {
                // Some business logic
            }
    }

在向cosmosClient注入mock或仅仅是模仿时，我会出错

Cannot mock/spy class com.azure.cosmos.CosmosClient
Mockito cannot mock/spy because
 - final class
    at org.springframework.boot.test.mock.mockito.MockitoTestExecutionListener.initMocks(MockitoTestExecutionListener.java:83)
    at org.springframework.boot.test.mock.mockito.MockitoTestExecutionListener.prepareTestInstance(MockitoTestExecutionListener.java:60)

Answer 1

CosmosClient是最后一个类，要模拟最终类，需要使用以下步骤配置Mockito特性：

在以下路径中创建一个文件：

src/test/resources/mockito-extensions/org.mockito.plugins.MockMaker

有以下内容：

mock-maker-inline

这应该允许模拟最后的类。
