By the end of the course, students will be able to: • discuss the challenges associated with the development and maintenance of large software systems, including the economic significance of software, and identify various software quality attributes (functionality, correctness, efficiency, usability, portability, etc.); • manage software configuration, including identifying configuration items, version control, change management, and configuration control; • compare and contrast different software process approaches (waterfall, prototyping, iterative – agile methodologies); • analyze and formalize functional and non-functional requirements of a software system, use UML to formalize requirements, and verify and validate requirements through inspections, prototypes, and formal models; • use UML for software design, create design and architectural diagrams, and verify and validate designs; • perform various types of testing on source code (white-box and black-box testing, unit, integration, and system testing), use inspection and review techniques and tools, and discuss the importance of testability, correctness, and reliability in the software development process; • understand project management tools such as WBS, Gantt, PERT, milestones, and deliverables, and effectively manage a software project; • collaborate and contribute effectively in a group environment, as demonstrated by their ability to complete a group project using a team assigned based on a survey reflecting their background and expected commitment.

Ability to develop small programs, knowledge of the structural elements of programming languages (functions, classes, packages), operational knowledge of Python or JavaScript. Knowledge of SQL and ability to define a database schema.

Lecture slides; Exercises; Exercise with solutions ; Lab exercises; Lab exercises with solutions; Video lectures (current year);

Exam: Group project; Computer-based written test in class using POLITO platform;

The exam is a written, individual test lasting 1 hour, conducted in class without access to books or notes, and delivered through the university's exam platform. It includes multiple-choice questions as well as some exercises and theory questions. Project work in teams of 5 students, developed exclusively during the course The project consists of documenting and validating a small software project in the TypeScript language. Deliverables include: - Requirements document - Use Case document - Class diagram and glossary - Docker container - Unit tests (black box, white box) - E2E tests The project is managed through a configuration management tool (GitLab) and makes use of open-source tools (e.g., Visual Studio Code, Jest, PlantUML, Cypress). Project evaluation is based on the quality of the deliverables. Weekly lab sessions are organized to support students in carrying out the project. Exam rules - Students may choose to take only the written exam. In this case, the maximum achievable score is 23 out of 33. - If the project is completed, a minimum score of 14/23 is required in the written exam to add the group project grade. - The project will receive a grade between 0 and 10. - The project must be carried out in parallel with the course and delivered at a fixed deadline that will be communicated during the course. - Honors (cum laude) are awarded starting from a total score > 32 points (project points included).

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
