OFFLINE TYPE CHECKING IN PROGRAMMING LANGUAGES

Disclosed is a method and system for detecting errors in source code of an application without executing the source code. Embodiments of the disclosed technique include detecting an error generating change at a specific location in source code of an application without executing the source code. The detection includes detecting an error in the changed portion of the source code as well dependencies of the changed portion of the source code. After the error detection, an error message containing information of the error is generated and stored in a storage unit. The information on the error includes (a) an indication of the change in source code, (b) the specific location, or (c) reason for the error. The types of error detected can include (i) a data type mismatch error, (ii) a syntax error, and (iii) other errors such as uninitialized variable access, null value or pointer dereference.
