Generating test data based on data value rules of linked data nodes

A computerized method for generating test data, the method comprising:

• identifying a plurality of data fields of a data structure;
• generating a plurality of linked data nodes, wherein each data node comprises a probability value and at least one data value rule for generating a data value for at least one of the plurality of data fields, and wherein each data node is at least one of a parent data node to at least one other data node of the plurality of linked data nodes or a child data node to another data node of the plurality of linked data nodes;
• collapsing parent data nodes into associated child data nodes to form a set of combined data nodes, wherein each combined data node includes a combined probability value based on probability values of associated parent data nodes and child data nodes and a combined data value rule set based on the at least one data value rules of the associated parent data nodes and child data nodes;
• generating, by a processor, test data values for the plurality of data fields based on the set of combined data nodes;
• populating, by the processor, a data structure instance of the data structure with the generated test data values;
• and
• executing at least one test on the populated data structure instance, whereby at least one test result is produced based on the generated test data values.

One or more computer storage media having computer-executable instructions for generating test data that, upon execution by a processor, cause the processor to at least:

• identify a plurality of data fields of a data structure;
• generate a plurality of linked data nodes, wherein each data node comprises a probability value and at least one data value rule for generating a data value for at least one of the plurality of data fields, and wherein each data node is at least one of a parent data node to at least one other data node of the plurality of linked data nodes or a child data node to another data node of the plurality of linked data nodes;
• collapse parent data nodes into associated child data nodes to form a set of combined data nodes, wherein each combined data node includes a combined probability value based on probability values of associated parent data nodes and child data nodes and a combined data value rule set based on the at least one data value rules of the associated parent data nodes and child data nodes;
• generate test data values for the plurality of data fields based on the set of combined data nodes;
• populate a data structure instance of the data structure with the generated test data values;
• and
• execute at least one test on the populated data structure instance, hereby at least one test result is produced based on the generated test data values.
