Constructor Summary

TimeBasedAlphanumericIdentifierGeneratorTest()

Method Summary

static junit.framework.TestSuite	suite() TestSuite for TimeBasedAlphanumericIdentifierGenerator.
void	testCanRetrieveTimeFromIdWithInternalOverflow() Test ensures, that generator can recalculate the time from the id even if internally an overflow had happened.
void	testCanRetrieveTimeFromIdWithoutInternalOverflow() Test ensures, that generator can recalculate the time from the id if internally no overflow had happened.
void	testDefaultPostfixSizeIsGoodEnough() Ensure that the default postfix size is big enough for a lot faster computers.
void	testDifferentGeneratorInstancesWillProduceStillUniqueIds() Test if different instances of the generator still deliver unique ids.
void	testIdentifierSizeIsConstant() Test constant size of generated identifier.
void	testIllegalPostfixSize() Test illegal values for the postfix size.
void	testIllegalStateWhenTooManyIdentifiersGenerated() Test that an IllegalStateException is thrown if no more unique identifiers can be generated.
void	testInternalOverflowStillIncreasesIds() Test if generator can handle an internal overflow as it may happen for time values and still delivers increasing ids.
void	testMayStartWithIdentifierOfZeros() Test that the generator can be tweaked to start with '0'.
