Predictive Test Case Coverage

A system comprising:

• at least one data processor;
• and
• memory storing instructions which, when executed by the at least one data processor, result in operations comprising:
• parsing a code base to identify methods having changes in a code base since a last code commit;
• traversing a call graph representing control flow relationships amongst each of the methods in the code base to identify a minimum number of test cases, wherein the minimum number of test cases are only those test cases that are implicated by the identified methods having changes in the code base;
• causing data characterizing the identified minimum number of test cases to be displayed in a graphical user interface;
• and
• executing the identified minimum number of test cases;
• wherein:
• the call graph is a directed call graph comprising a plurality of connected nodes;
• a first subset of the connected nodes are method nodes representing each method in the code base in which unidirectional edges connecting method nodes correspond to invocations by a calling method to a callee method;
• a second subset of the connected nodes are test case nodes representing each of a plurality of available test cases to test the code base, the test case nodes are each coupled to one or more method nodes by unidirectional edges that correspond to coverage of the method by the test case corresponding to the connected test case node;
• the call graph is traversed from each method node corresponding to the identified methods changed in the code base to identify test cases covering such methods.
