Subject [jira] Created: (DERBY-5107) BasicInMemoryDbTest depends on implicit ordering of test cases

BasicInMemoryDbTest depends on implicit ordering of test cases
--------------------------------------------------------------

                 Key: DERBY-5107
                 URL: https://issues.apache.org/jira/browse/DERBY-5107
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions: 10.8.0.0
            Reporter: Knut Anders Hatlen


BasicInMemoryDbTest only works if the test cases run in one particular order. This should
either be made explicit in the test, or the test should be changed to work regardless of the
ordering.

For example, if testEnginehutdown (sic) runs before testShutdown, testShutdown will fail:

http://dbtg.foundry.sun.com/derby/test/Daily/jvm1.7/testing/testlog/lin/1076682-suitesAll_diff.txt

11) testShutdown(org.apache.derbyTesting.functionTests.tests.memorydb.BasicInMemoryDbTest)junit.framework.AssertionFailedError:
Warning(s) when creating database: Database 'memory:/tmp/myDB' not created, connection made
to existing database instead.
	at org.apache.derbyTesting.functionTests.tests.memorydb.MemoryDbManager.createDatabase(MemoryDbManager.java:226)
	at org.apache.derbyTesting.functionTests.tests.memorydb.MemoryDbManager.createDatabase(MemoryDbManager.java:181)
	at org.apache.derbyTesting.functionTests.tests.memorydb.BasicInMemoryDbTest.testShutdown(BasicInMemoryDbTest.java:189)

Also, when running from classes, some test cases (like testEnginehutdown and testDeleteWhenInUse)
will fail with no suitable driver if they run before some other test case has called MemoryDbManager.getConnection():

1) testEnginehutdown(org.apache.derbyTesting.functionTests.tests.memorydb.BasicInMemoryDbTest)java.sql.SQLException:
No suitable driver found for jdbc:derby:memory:/tmp/myDB;create=true
	at java.sql.DriverManager.getConnection(DriverManager.java:640)
	at java.sql.DriverManager.getConnection(DriverManager.java:222)
	at org.apache.derbyTesting.functionTests.tests.memorydb.BasicInMemoryDbTest.testEnginehutdown(BasicInMemoryDbTest.java:209)
