Test Coverage and Code Coverage

Test coverage is often confused with Code Coverage. Although both metrics are used to evaluate the quality of application code, code coverage is a term to describe what percentage of the application code is exercised when a user is interacting with the application. Test Coverage, on the other hand, is testing every business requirement at least once and is clearly a QA team activity.

How to attain more Test Coverage in less time

Testers are always running on a tight schedule and have to focus on ensuring maximum coverage within the stipulated time primarily. In order to achieve this, there are few methods described below:

• Using Automation Tools: One of the modern testing methods any company or any testing group can adopt is the usage of the right Automation Tool. Nowadays, there are plenty of tools in the market, making a testers life easy. One must identify the right testing tool for the application.

Test Coverage Metrics and Best Practices

• Code coverage = (Number of lines of code exercised by the test suites)/(total number of lines of code)*100

• Requirement coverage = [(Total number of requirements) – (Total number of missed requirements)]/(Total number of requirements)*100

Best Practices of Test Coverage

• Segregate the business requirements/modules as per their criticality, frequency of use and most complex workflows.

• Develop a requirement traceability matrix for the modules/requirements.

• Utilize the test coverage as a measure for “untested paths” instead of “false sense of security.

• Develop automated suites using frameworks integrated with code coverage utilities.

• Measure the code coverage for each release and plan to improve it with every subsequent release.

• Utilize the metrics like ‘Defect density’, ‘feature wise defect distribution’ and ‘Defect removal efficiency’ as a guide to ensure improved coverage for subsequent releases.
