Automated test generation for Scratch programs
Empirical Software Engineering, 2023 AbstractThe importance of programming education has led to dedicated educational programming environments, where users visually arrange block-based programming constructs that typically control graphical, interactive game-like programs. TheScratchprogramming environment is particularly popular, with more than 90 million registered users at the time of ...
