Nopol: Automatic Repair of Conditional Statement Bugs in Java Programs

Understand

We propose NOPOL, an approach to automatic repair of buggy conditional statements (i.e., if-then-else statements).

• This approach takes a buggy program as well as a test suite as input and generates a patch with a conditional expression as output.
• The test suite is required to contain passing test cases to model the expected behavior of the program and at least one failing test case that reveals the bug to be repaired.
• The process of NOPOL consists of three major phases.
