Method Details

doCompare

protected String doCompare(ITable expectedTable,
 ITable actualTable,
 int rowNum,
 String columnName,
 DataType dataType,
 Object expectedValue,
 Object actualValue)
                    throws DatabaseUnitException

Do the comparison and return a fail message or null if comparison passes. This implementation calls isExpected(ITable, ITable, int, String, DataType, Object, Object).

Specified by:

doCompare in class ValueComparerBase

Throws:

DatabaseUnitException

• ValueComparer.compare(ITable, ITable, int, String, DataType, Object, Object)

makeFailMessage

protected String makeFailMessage(Object expectedValue,
 Object actualValue)

Makes the fail message using getFailPhrase().

Returns:

the formatted fail message with the fail phrase.

isExpected

protected abstract boolean isExpected(ITable expectedTable,
 ITable actualTable,
 int rowNum,
 String columnName,
 DataType dataType,
 Object expectedValue,
 Object actualValue)
                               throws DatabaseUnitException

Returns:

true if comparing actual to expected is as expected.

Throws:

DatabaseUnitException

getFailPhrase

protected abstract String getFailPhrase()

Returns:

The text snippet for substitution in ValueComparerBase.BASE_FAIL_MSG.
