Method Detail

suite

public static junit.framework.Test suite()

Create a suite of tests.

setUp

protected void setUp()

Set up the test environment.

Overrides:

setUp in class junit.framework.TestCase

tearDown

protected void tearDown()
                 throws java.lang.Exception

Tear down the test environment.

Overrides:

tearDown in class BaseJDBCTestCase

Throws:

java.lang.Exception

testConcurrentFetchAndDelete

public void testConcurrentFetchAndDelete()
                                  throws java.lang.Exception

Regression test case for DERBY-4676. Before the fix, fetching a row by its row location would sometimes fail with a NullPointerException if the row was deleted while the fetch operation was waiting for a lock.

Throws:

java.lang.Exception

startThread

private void startThread(Derby4676Test.HelperThread thread)

Start a helper thread and register it for automatic clean-up in tearDown().

Parameters:

thread - the helper thread to start
