Lecture 15 - Announcements / Notes

Announcements

• Prac 4 is this Friday
• Exam 3 is next Friday
• We’re covering a bit of new material on software testing in class today; this will be on one of the Prac 3 problems.

Goals

• Know what a unit test is
• Know the behavior of Python’s assert statement and how to use it when writing unit tests
• Be able to write a simple test case in a pytest test program.
• Know how to use input space partitioning and boundary value analysis to devise a thorough set of test cases for simple Python functions.

Plan for Today

• Software testing:
  • The behavior of the assert statement
  • Anatomy of a pytest test program, using sixes_test.py as an example
  • Input space partitioning and boundary value analysis, using gradecalc.letter_grade as an example
  • Write a test suite in gradecalc_test.py
• E15T
• POTD 15 setup and overview
• Options:
  • POTD 14
  • find_all
