Examples of TestInputStream

org.apache.derbyTesting.functionTests.util.TestInputStream
TestInputStream class is a InputStream which returns a lot of data which can be inserted into a LOB.
org.apache.jackrabbit.mk.test.util.TestInputStream
An {@code InputStream} based on pseudo-random data useful for testing.
Instances created with identical parameter values do produce identical byte sequences.
org.apache.jackrabbit.oak.benchmark.TestInputStream
An input stream that returns a given number of dummy data. The returned data is designed to be non-compressible to prevent possible compression mechanisms from affecting performance measurements.
