A software firm requires that every new feature pass an automated test suite before it is released. Last quarter, the firm added many new tests to the suite, and the proportion of features that failed at least one test before release rose from 15 percent to 40 percent. A manager argues that this rise shows the quality of the firm's code has deteriorated. Which of the following, if true, most weakens the manager's argument? (Select ONE answer.)
- The firm hired several new programmers right at the start of last quarter, as the failure rate began climbing.
- Many of the newly added tests check for defects that the previous suite had never been able to detect.
- The total number of features the firm released last quarter was greater than the number released the previous quarter.
- Some features that failed at least one test were released to customers anyway after only minor revisions.
- Competing software firms rely on automated test suites noticeably smaller than this firm's own suite.
