Systems and Methods for Automatic Test Generation

A computer-implemented method comprising:

• obtaining a prioritized list of candidate input values, wherein the prioritized list of candidate input values includes at least one candidate input value based on domain knowledge associated with a testable component;
• updating the prioritized list of candidate input values by:
• obtaining a first candidate test associated with the testable component, wherein the first candidate test comprises an input having an input value;
• causing an execution of the first candidate test and recording data generated during the execution of the first candidate test;
• determining a candidate input value based on the data generated during the execution of the first candidate test;
• adding the candidate input value to the prioritized list of candidate input values according to a priority value associated with the candidate input value;
• and
• modifying the first candidate test to create a second candidate test based on the first candidate test, the second candidate test including a modified input wherein the modified input value is selected from the prioritized list of candidate input values;
• and
• generating a test associated with the testable component based on the first candidate test or the second candidate test.

A system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media that collectively store instructions that, when executed by the one or more processors, cause the system to perform operations, the operations comprising:
• obtaining a prioritized list of candidate input values, wherein the prioritized list of candidate input values includes at least one candidate input value based on a domain knowledge associated with a testable component;
• obtaining a first candidate test associated with the testable component, wherein the current candidate test comprises an input having an input value;
• causing an execution of the first candidate test and recording data generated during the execution of the first candidate test;
• determining a candidate input value based on the data generated during the execution of the first candidate test;
• adding the candidate input value to the prioritized list of candidate input values according to a priority value associated with the candidate input value;
• modifying the first candidate test to create a second candidate test based on the first candidate test, the second candidate test including a modified input value different to a corresponding input value of the first candidate test, wherein the modified input value is selected from the prioritized list of candidate input values;
• and
• generating a test associated with the testable component based on the first candidate test or the second candidate test.
