Examples of java.io.ByteArrayOutputStream

java.io.ByteArrayOutputStream
ByteArrayOutputStream is a class whose underlying stream is represented by a byte array. As bytes are written to this stream, the local byte array may be expanded to hold more bytes. @see ByteArrayInputStream

        ts.getTrace("test").debug(new Exception("error"), "test");
        ts.close();
        String outString = new String(out.toByteArray());
        assertContains(outString, "error");
        assertContains(outString, "Exception");
