The article "Merge coverage: With fewer tests to 100 percent code coverage" in Embedded Software Engineering discusses the importance of code coverage in software development, particularly in safety-critical systems. It highlights the need to achieve 100% code coverage, which can be a time-consuming and resource-intensive process. The author Frank Büchner proposes a solution to reduce the number of test cases required to achieve 100% code coverage by combining coverage measurements from different test activities, such as unit testing and integration testing. This approach, called "Hyper-Coverage," can help save time and effort in the testing process.
