The invention discloses a DF file verification method based on the ARINC661. The DF file verification method based on the ARINC661 is characterized by comprising the following steps that firstly, a DF file is led in, information of the DF file is read and stored in a unified global variable, after the DF file is led in successively, data are analyzed and displayed according to a logical hierarchical structure, and attribute values and types of all parts are displayed in rows; secondly, a CDS server is started; thirdly, dynamic verification is performed on the DF file; fourthly, a test scrip of the Python format is automatically generated according to attributes of the corresponding parts of a DF and based on the ARINC661 protocol specifications, an execution environment and management are provided, original manual operation is converted into a script file to be stored, and therefore the verification process can be repeated. According to the DF file verification method based on the ARINC661, time in analyzing question reasons can be reduced, more emphasis of project testing can be put on logical functions, and therefore the development progress and the development efficiency of a whole project are ensured.
