Example of issues to be tested: Open Office and WordPad have inconsistencies in displaying font sizes, which can be a serious problem for users.

• Open Office displays different font sizes as the same.

• WordPad also doesn't handle differences in size consistently.

• Side-by-side comparisons with a reference program can help in making more thorough inspections.

The video discusses the challenges of testing fonts and formatting in different programs.

• Open Office, Word, and professional desktop publishing programs are designed to provide professional quality formatting.

• Testing fonts and formatting requires checking with every font and character, as well as interactions with other variables.

• Measuring character height in points is complicated, so simpler methods like comparing character sizes within the same typeface are often used.

• The Oracle idea is to determine whether a program passes or fails a test by comparing results to an expected result, but there are challenges with setting accurate expectations.

The section discusses the challenges of relying on human judgment, credibility, and consistency when determining if a program is working correctly.

• The Oracle rarely helps in determining the seriousness of a bug.

• The credibility problem arises when reporting a program's incorrect behavior.

• Consistency heuristics can be used to compare a program's results with expectations.

Programmers should not be solely responsible for defects in a program; the responsibility lies with those who provide the specifications.

• Programmers may claim they did what they were told to do, but the program can still be defective.

• To challenge this perception, one must conduct their own research and find sources of information that either support or refute the impression.

• Some companies may discourage testers from evaluating product design, focusing solely on implementation.

• It is important to choose arguments carefully and ensure the validity of sources before speaking up.

• Sharing valuable insights can benefit both the company and the individual in the long run.
