What is line coverage?
Definition of Line Coverage Metric The Line Coverage of a program is the number of executed lines divided by the total number of lines. Only lines that contain executable statements are considered, not those with pure declarations.
What is method coverage?
Method coverage is a code coverage metric that measures whether a method was entered at all during execution.
What is code coverage analysis?
Code Coverage Analysis is the process of discovering code within a program that is not being exercised by test cases. This information can then be used to improve the test suite, either by adding tests or modifying existing tests to increase coverage.

Is 100 percent code coverage possible?
It’s almost impossible to get 100% code coverage for any significant body of code. Covering every branch, every piece of error handling code, and every piece of UI code is extremely difficult. (I say “almost impossible” because SQLite has done it. SQLite has 711 times as much test code as it has production code.)

How code quality is measured?
It relates to the number of defects and availability of the software. Number of defects can be measured by running a static analysis tool. Software availability can be measured using the mean time between failures (MTBF). Low defect counts are especially important for developing a reliable codebase.
What is code smell in agile?
