Method Detail

assertEquals

public static void assertEquals(IDataSet expectedDataSet,
                                IDataSet actualDataSet)
                         throws java.lang.Exception

Deprecated. Use Assertion.assertEquals

Asserts that the two specified dataset are equals. This method ignore the tables order.

Throws:

java.lang.Exception

assertEquals

public static void assertEquals(ITable expectedTable,
                                ITable actualTable)
                         throws java.lang.Exception

Deprecated. Use Assertion.assertEquals

Asserts that the two specified tables are equals. This method ignore the table names, the columns order, the columns data type and the primary keys.

Throws:

java.lang.Exception

getQualifiedName

public static java.lang.String getQualifiedName(java.lang.String prefix,
                                                java.lang.String name)

Returns the specified name qualified with the specified prefix. The name is not modified if the prefix is null or if the name is already qualified.

Example:
getQualifiedName(null, "NAME") returns "NAME". getQualifiedName("PREFIX", "NAME") returns "PREFIX.NAME" and getQualifiedName("PREFIX2", "PREFIX1.NAME") returns "PREFIX1.NAME".

Parameters:

prefix - the prefix

name - the name

Returns:

the qualified name

getQualifiedName
