Date Sun, 15 Jul 2012 16:35:33 GMT

    [ https://issues.apache.org/jira/browse/GORA-53?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13414694#comment-13414694

Kazuomi Kashii commented on GORA-53:
------------------------------------

Tests run: 28, Failures: 9, Errors: 5, Skipped: 0, Time elapsed: 21.147 sec <<< FAILURE!

There are three types of failures or errors.

1) AssertionFailedError

testSchemaExists(org.apache.gora.cassandra.store.TestCassandraStore)  Time elapsed: 0.883
sec  <<< FAILURE!
junit.framework.AssertionFailedError
        at junit.framework.Assert.fail(Assert.java:48)
        at junit.framework.Assert.assertTrue(Assert.java:20)
        at junit.framework.Assert.assertTrue(Assert.java:27)
        at org.apache.gora.store.DataStoreTestUtil.testSchemaExists(DataStoreTestUtil.java:131)
        at org.apache.gora.store.DataStoreTestBase.testSchemaExists(DataStoreTestBase.java:164)

It is because CassandraStore's schemaExists() method returns always false.

  public boolean schemaExists() throws IOException {
    LOG.info("schema exists");
    return false;
  }

2) StackOverflowError

testDeleteByQuery(org.apache.gora.cassandra.store.TestCassandraStore)  Time elapsed: 0.62
sec  <<< ERROR!
java.lang.StackOverflowError
        at org.apache.gora.persistency.ListGenericArray.compareTo(ListGenericArray.java:32)
        at org.apache.avro.generic.GenericData.compare(GenericData.java:487)

I have no clue. Maybe a bug of gora-core ?

3) ComparisonFailure

testUpdate(org.apache.gora.cassandra.store.TestCassandraStore)  Time elapsed: 0.68 sec  <<<
FAILURE!
junit.framework.ComparisonFailure: expected:<[content0]> but was:<[?^A^@^B^@^@^@^Pget_range_slices^@^@^@5^O^@^@^L^@^@^@^A^K^@^A^@^@^@^Nhttp://a.com/a^O^@^B^L^@^@^@^B^L^@^A^K^@^A^@^@^@^Cc:u^K^@^B^@^@^@^Nhttp://a.com/a

        at junit.framework.Assert.assertEquals(Assert.java:85)
        at junit.framework.Assert.assertEquals(Assert.java:91)
        at org.apache.gora.store.DataStoreTestUtil.testUpdateWebPage(DataStoreTestUtil.java:296)
        at org.apache.gora.store.DataStoreTestBase.testUpdate(DataStoreTestBase.java:267)

It seems a bug of gora-cassandra.

> As per this thread [1], it is absolutely essential that we get some tests for the Cassandra
module. Therefore this task should act as a summary task to manage all test which are hereby
proposed.
> Realistically, this is going to take a good while, so I have marked it for 0.2 and 0.3-incubating
releases.
