### Question:
LogFile implements Closeable { LogFileCursor<K, V> getCursor() throws ChangelogException { return new LogFileCursor<>(this); } private  LogFile(final File logFilePath, final RecordParser<K, V> parser, boolean isWriteEnabled); @Override void close(); @Override int hashCode(); @Override boolean equals(Object that); @Override String toString();  }### Answer:
@Test public void testCursor() throws Exception { try (LogFile<String, String> changelog = getLogFile(RECORD_PARSER); DBCursor<Record<String, String>> cursor = changelog.getCursor()) { assertThatCursorCanBeFullyRead(cursor, 1, 10); } }
@Test(dataProvider="cursorPositionTo") public void testCursorPositionTo(String key, KeyMatchingStrategy matchingStrategy, PositionStrategy positionStrategy, boolean positionShouldBeFound, int cursorShouldStartAt, int cursorShouldEndAt) throws Exception { try (LogFile<String, String> changelog = getLogFile(RECORD_PARSER); LogFileCursor<String, String> cursor = changelog.getCursor()) { boolean success = cursor.positionTo(key, matchingStrategy, positionStrategy); assertThat(success).isEqualTo(positionShouldBeFound); if (cursorShouldStartAt >= 0) { assertThatCursorCanBeFullyRead(cursor, cursorShouldStartAt, cursorShouldEndAt); } else { assertThatCursorIsExhausted(cursor); } } }
