Many people equate 100 percent unit test coverage with high code quality, but that is not enough. Code coverage tools only measure whether the tests execute the code; they make no judgment on the effectiveness of the tests. Testers should review unit tests, even if they have high coverage levels, and either help improve the tests or supplement them with extra tests where necessary.

Test coverage is a strategy to help us spend scarce testing time on the right priorities. When things were tested last, how much automation coverage we have, how often the customers use the feature, and how critical the feature is to application are all factors to consider. Here are some ideas for keeping quality high when you're transitioning to continuous delivery.

In order to fully embrace agile and create an environment where individuals want to work together as a team, managers have to move from a role of dictation to one of direction and mentorship. Instead of making all the decisions, managers need to trust their team members and empower them to solve problems on their own, innovate, and fail—or succeed.

Adopting service virtualization can allow organizations to achieve more effective software development and testing by removing traditional test environment bottlenecks. Integrating service virtualization within the continuous delivery pipeline using containerization helps teams reach the level of flexibility required by today's competitive markets.
