Method for automatically validating cots and device for implementing the method

A device for testing a software component implemented in a host system on the basis of one or more test campaigns, a test campaign comprising computer test cases and being associated with input test data, the device being comprising:

• a processing unit configured for:
• executing the computer test cases of each test campaign for an operating time of said software component, which provides output test data associated with each test campaign;
• and
• determining a reference operating model and a data partition on the basis of the input and output test data associated with each test campaign, a reference operating model being determined by applying a machine learning algorithm to said input and output test data, a data partition being determined by applying a data partitioning algorithm to said input and output test data;
• a test unit configured for:
• running said software component using input production run data, which provides output production run data;
• determining an operating characteristic of said software component on the basis of the reference operating models according to a comparison between the input and output production run data and the data from the data partitions associated with said one or more test campaigns.
