cassandraunit无法启动EmbeddedCassandraServer

Question

我想对我的cassandra service进行单元测试，因此找到cassandra-unit是我可以使用的。因此，我使用cassandra-unit:3.1.1.0对我的cassandraservice进行单元测试，然后找到了Here的示例项目，但我无法运行embedded cassandra服务器来运行我的单元测试。请告诉我有什么问题，或者是否有其他库可用于测试cassandra。

我的测试类

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({ CassandraUnitTestExecutionListener.class })
@CassandraDataSet(value = { "simple.cql" })
@EmbeddedCassandra(configuration = "cassandra.yml")
public class CassandraServiceTest {

    @Test
    public void should_execute_batch() throws Exception {
        ResultSetFuture result = session.executeAsync(batch);
        assertNotNull(result);
    }
}

发生超时错误 -

我总是出错时间，不知道如何增加EmbeddedServer

的超时间隔

16:14:13.056 [main] ERROR org.cassandraunit.utils.EmbeddedCassandraServerHelper - Cassandra daemon did not start after 10000 ms. Consider increasing the timeout

你可以看一下这个帖子： https://github.com/jsevellec/cassandra-unit/issues/128

基本上你应该增加超时： https://github.com/jsevellec/cassandra-unit/pull/127

在带有配置文件的@EmbeddedCassandra注释中，您还可以设置超时。
