Method Details

compare

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

Compare expected and actual values. This implementation calls doCompare(ITable, ITable, int, String, DataType, Object, Object).

Specified by:

compare in interface ValueComparer

Parameters:

expectedTable - Table containing all expected results.

actualTable - Table containing all actual results.

rowNum - The current row number comparing.

columnName - The name of the current column comparing.

dataType - The DataType for the current column comparing. Use DataType.compare(Object, Object) for equal, not equal, less than, and greater than comparisons.

expectedValue - The current expected value for the column.

actualValue - The current actual value for the column.

Returns:

compare failure message or null if successful compare.

Throws:

DatabaseUnitException - if the comparison cannot be performed.

doCompare

protected abstract 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.

Parameters:

expectedTable - Table containing all expected results.

actualTable - Table containing all actual results.

rowNum - The current row number comparing.

columnName - The name of the current column comparing.

dataType - The DataType for the current column comparing.

expectedValue - The current expected value for the column.

actualValue - The current actual value for the column.

Returns:

compare failure message or null if successful compare.

Throws:

DatabaseUnitException - if the comparison cannot be performed.
