java - 在 Dropwizard 中以编程方式运行迁移

Question

我有 dropwizard-application (0.7.0)，我想为其运行集成测试。

我已经使用 DropwizardAppRule 设置了一个集成测试，如下所示:

@ClassRule
public static final DropwizardAppRule<MyAppConfiguration> RULE =
        new DropwizardAppRule<MyAppConfiguration>(
                MyApplication.class, Resources.getResource("testconfiguration.yml").getPath());

当我尝试使用它运行以下测试时，它不起作用，因为我还没有运行我的迁移。运行迁移的最佳方式是什么？

测试:

@Test
public void fooTest() {
    Client client = new Client();
    String root = String.format("http://localhost:%d/", RULE.getLocalPort());
    URI uri = UriBuilder.fromUri(root).path("/users").build();
    client.resource(uri).accept(MediaType.APPLICATION_JSON).type(MediaType.APPLICATION_JSON).post(User.class, new LoginUserDTO("email@email.com", "password"));
}

配置:

 public class MyAppConfiguration extends Configuration {
@Valid
@NotNull
private DataSourceFactory database = new DataSourceFactory();

@JsonProperty("database")
public DataSourceFactory getDataSourceFactory() {
    return database;
}

@JsonProperty("database")
public void setDataSourceFactory(DataSourceFactory dataSourceFactory) {
    this.database = dataSourceFactory;
}

感谢 Kimble 和 andersem 让我走上正轨。这是我在 @BeforeClass 方法中想到的:

// Create the test database with the LiquiBase migrations.
@BeforeClass
public static void up() throws Exception
{
    ManagedDataSource ds = RULE.getConfiguration().getMainDataSource().build(
        RULE.getEnvironment().metrics(), "migrations");
    try (Connection connection = ds.getConnection())
    {
        Liquibase migrator = new Liquibase("migrations.xml", new ClassLoaderResourceAccessor(), new JdbcConnection(connection));
        migrator.update("");
    }
}
