dremio 开发测试简单说明

目前官方关于如何进行相关开发测试的明确的文档说明，但是我们基于官方提供的测试用例可以基本了解

plugin 测试简单说明

参考自官方的测试demo
需要做的事情，初始化一个dremio catalog 服务（进行插件管理），注册自己开发的插件，进行查询测试（注意测试基类需要继承自BaseTestQuery我们可以利用好多base 的方法，test...）

• 简单参考

 

public class TestSubPathFileSystemPlugin extends BaseTestQuery {

  @ClassRule

  public static TemporaryFolder testFolder = new TemporaryFolder();

 

  protected static File storageBase;

 

  @Rule

  public TemporarySystemProperties properties = new TemporarySystemProperties();

 

  @Before

  public void before() {

    properties.set(DremioConfig.LEGACY_STORE_VIEWS_ENABLED, "true");

  }

 

  @BeforeClass

  public static void setup() throws Exception {

    testNoResult("alter system set \"%s\" = 1", FileDatasetHandle.DFS_MAX_FILES.getOptionName());

    generateTestData();

    addSubPathDfsPlugin();

  }

 

  @Test

  public void queryValidPath() throws Exception {

    test("SELECT * FROM subPathDfs.\"tblInside.csv\"");

    test("SELECT * FROM subPathDfs.\"dirInside/tbl.csv\"");

  }

maven 依赖包

  注意需要引用dremio kernel 的test 包，同时repo 需要使用dremio 自己的

说明

以上是一个简单的说明，实际还需要自己多研究，官方已经提供了好多demo
