• No, it is below the minimum test coverage rate

What is the code coverage formula?

• Code Coverage Percentage = (Number of lines of code executed) / (Total Number of lines of code in an application) * 100
• Code Coverage Percentage = (Number of tests executed) / (Total number of tests) * 100
• Code Coverage Percentage = (Number of lines of code executed by tests) / (Total number of lines of code) * 100
• Code Coverage Percentage = (Number of assertions) / (Number of test cases) * 100

How code coverage is generated?

• By counting the number of executed lines of code
• By dividing the number of executed lines by the total number of lines of code
• By analyzing the test cases and their coverage
• By using a code coverage tool to track code execution

Why increase code coverage?

• To improve the overall quality of the software
• To ensure that recent changes do not break the code
• To provide developers with confidence in their code
• All of the above
