Advanced Swift 2 Application Development (Video 31)

This video tutorial explains the concept of code coverage in software testing, particularly using Xcode 7. It covers the importance of code coverage in ensuring a stable codebase and provides a step-by-step guide on setting up and accessing code coverage reports in Xcode. The tutorial also discusses how to analyze these reports to improve code stability and suggests further resources for learning about code coverage and unit testing.

What is the primary purpose of code coverage reports in unit testing?

• To measure the performance of the code

• To optimize the code for faster execution

• To determine the percentage of code tested by unit tests

• To identify syntax errors in the code

Which version of Xcode introduced the ability to access code coverage reports?

• Xcode 6

• Xcode 8

• Xcode 5

• Xcode 7

What is the first step in setting up code coverage reports in Xcode?

• Check for syntax errors

• Run all unit tests

• Edit the scheme to gather coverage data

• Optimize the codebase

How can you access the coverage report after running tests in Xcode?

• By navigating to the 'Test Inspector' and selecting 'Jump to Report'

• By checking the 'Debug' tab

• By opening the 'Console' window

• By clicking on the 'Build' tab

What should you do if certain parts of your codebase are not covered by tests?

• Delete the untested code

• Optimize the existing tests

• Write more tests for those areas

• Ignore them as they are not important
