Class TestResultSetUtil

java.lang.Object

org.teiid.test.util.TestResultSetUtil

public class TestResultSetUtil
extends Object

TestResultSetUtil was built in order to override the #printThrowable(Throwable, PrintStream) method in order to call out.print instead of out.println This is because the println adds a line terminator, and when the result file is in turn used for comparison it fails because of the line terminator.

compareThrowable

public static List compareThrowable(Throwable t,
                                    String query,
                                    File expectedResultsFile,
                                    boolean printToConsole)
                             throws IOException

Throws:

IOException

printThrowable

public static void printThrowable(Throwable t,
                                  String sql,
                                  PrintStream out)

getPrintStream

public static PrintStream getPrintStream(OutputStream resultsOutput,
                                         BufferedReader expectedResultsInput,
                                         PrintStream defaultPrintStream)

Gets a PrintStream implementation that uses the input parameters as underlying streams

Parameters:

resultsOutput - an output file for result data. If null, results will only be written to the defaul stream.

expectedResultsInput - the reader for expected data. If null, actual data is never compared against expected results.

defaultPrintStream - if not null, this utility will always write to this stream. Typically this is System.out

Returns:

the single PrintStream that wraps all the input streams for writing and comparison.

                                            SQLException

Compares the actual results with the expected results.

Parameters:

rs - the result of the execution

maxColWidth - the max width a column is allowed to have

printMetadata - writes the metadata if true

resultsFile - output file to which the results will be written. Can be null.

expectedResultsFile - expected results file with which to compare the results. Can be null.

printToConsole - writes to System.out if true

Returns:

The List of line numbers which differ between the actual and expected results.

Throws:

IOException

SQLException

                           throws SQLException

Prints the ResultSet (and optionally the ResultSetMetaData) to a stream. If you're using the stream from getPrintStream(), then you can also compare data with expected results.

Parameters:

rs -

maxColWidth - the max width a column is allowed to have. The column will be wider than this value only if the column name is longer.

printMetadata -

out -

Throws:

SQLException
