Automatically redirecting method calls for unit testing

A computer system for unit testing software application code, the system comprising:

• a processor and memory configured to execute software instructions;
• a method identification component configured to identify methods in a software application;
• a method cloning component configured to clone an identified method to create a modifiable copy of the method for unit testing so that the system can modify the method to enhance testability without requiring modifications to the original method;
• a call identification component configured to identify calls to one or more other methods within an identified method;
• a call redirection component configured to replace an identified call to a method with a call to an intercept method;
• a unit test store configured to store one or more unit tests for testing the software application;
• and an intercept handling component configured to receive calls to intercept functions and invoke one or more stored unit tests to perform unit testing.

A computer-readable storage medium comprising instructions for controlling a computer system to process a call to an intercepted software method during testing, wherein the instructions, when executed, cause a processor to perform actions comprising:

• receiving a call to an interception method for unit testing a software application;
• determining whether a mock object exists that is associated with the received interception method;
• upon determining that no mock object exists for the received interception method, invoking an original target associated with a location of the received call to the interception method;
• and
• upon determining that a mock object exists for the received interception method, substituting the mock object for the original target associated with the location of the received call to the interception method and invoking the mock object.
