public class ErrorStreamTest
extends BaseJDBCTestCase

Tests related to the Derby error stream. This test has been converted to junit from the old harness tests logStream.java and errorStream.java. The testDefault method is based on logStream.java, the other test* methods are from errorStream.java.

Field Detail

FILE_PROP

private static final java.lang.String FILE_PROP

Constant Field Values

METHOD_PROP

private static final java.lang.String METHOD_PROP

See Also:

Constant Field Values

FIELD_PROP

private static final java.lang.String FIELD_PROP

See Also:

Constant Field Values

runNo

private static int runNo

runNo keeps track of which run we are in to generate unique (within a JUnit run) names for files that are used in the test. Has to be static.

fileStreamFile

private java.io.File fileStreamFile

File used when FILE_PROP is set, it maps to file -file-.log

methodStream

private static java.io.OutputStream methodStream

See doc for getStream() below. Has to be static.

methodStreamFile

private java.io.File methodStreamFile

fieldStream

public static java.io.OutputStream fieldStream

Field fieldStream used by Derby when FIELD_PROP is set, so it needs to be public and static. Maps to file -field-.log

fieldStreamFile

private java.io.File fieldStreamFile

errStream

private java.io.OutputStream errStream

Field errStream used as redirection for System.err to be able to checks its (non-)use in the scenarios. We first tried to merge it with System.out and let the harness compare outputs, but this gave intermittent merging differences, so abandoned. Maps to file -err-.log

errStreamFile

private java.io.File errStreamFile
