US 2025/0094324 A1 · INTELLIGENT GENERATION OF UNIT TESTS

Abstract

Arrangements for intelligent generation of unit tests are provided. A facade of a method of a class isolating code from a subsystem may be generated. The facade may include input variables and output variables. The facade of the method may be parsed to identify allowed input values for the input variables and expected output values for the output variables. User input specifying one or more parameters for the input variables may be received based on the identified allowed input values. Based on the received user input, a database table with every combination of the input variables with the output variables may be populated and stored in a data store. A unit test method may be executed on each row of the database table. Outputs of the unit test method may be compared to corresponding expected output values in the database table to determine whether there is a match.

Dependent claims

A system, comprising:

at least one data processor;
and
at least one memory storing instructions, which when executed by the at least one data processor, result in operations comprising:
generating a facade of a method of a class, wherein the facade comprises input variables and output variables, and wherein the facade isolates code from a subsystem;
parsing the facade of the method, wherein the parsing identifies allowed input values for the input variables and expected output values for the output variables;
receive user input specifying one or more parameters for the input variables based on the identified allowed input values for the input variables;
based on the received user input, populating a database table with every combination of the input variables with the output variables;
storing the database table in a data store;
executing a unit test method on each row of the database table;
comparing outputs of the unit test method to corresponding expected output values in the database table;
and
determining whether the outputs of the unit test method match the corresponding expected output values in the database table.
