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, how to set up code coverage in Xcode, and how to analyze the resulting reports. The tutorial also provides guidance on improving test coverage 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 determine the percentage of code tested by unit tests

• To identify syntax errors in the code

• To optimize the code for faster execution

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

• Xcode 8

• Xcode 7

• Xcode 5

• Xcode 6

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

• Edit the scheme

• Open the project settings

• Run the tests

• Compile the code

After running tests, where can you find the code coverage report in Xcode?

• In the build settings

• In the test inspector

• In the debug console

• In the project navigator

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

• Increase the code complexity

• Delete the untested code

• Write more tests for those parts

• Ignore them if the code is working fine
