Methods and apparatus for debuggers supporting method restart are described. A method comprises implementing a user interface (UI) enabling a user to submit a request, via a single interaction within a debugging session, to restart execution of an invocable operation of a program. The method further comprises, in response to a request to restart an invocable operation, designating, as the source code line whose corresponding executable code is to be executed next, the first line of source code of the particular invocable operation that corresponds to an executable operation. The method includes indicating that execution of the program is to be resumed at the first line, and resuming execution of the program at the first line.
