### Question:
InfluxLineProtocolRecordReader implements RecordReader { @Override public RecordSchema getSchema() throws MalformedRecordException { return schema; } InfluxLineProtocolRecordReader(@Nullable final InputStream in,
                                          @NonNull final Charset charset); @Override Record nextRecord(final boolean coerceTypes, final boolean dropUnknownFields); @Override RecordSchema getSchema(); @Override void close();  }### Answer:
@Test public void schemaNotNull() throws SchemaNotFoundException, MalformedRecordException, IOException { RecordReader recordReader = readerFactory.createRecordReader(variables, toInputData(), -1,logger); RecordSchema schema = recordReader.getSchema(); Assert.assertNotNull(schema); }
