Looking Glass
Scott Alexander Turner · 2015
Looking Glass (https://github.com/sturner84/LookingGlass) is a library designed to support the testing of students' C++ code through reflection. Instructors can design tests that compile even if there are mismatches between the instructor's and student's code (like misspelled function names or parameters that do not have the expected types). Using the automatically generated metadata, instructors can search for and call functions or methods in the student code, including the main function, while providing feedback (rather than a compile error) if the required code is not found. Although not suitable for all C++ programs, Looking Glass was designed to support instructors in introductory and intermediate classes and to be transparent to the students.
