Coverage is used to help developers determine what lines of code were executed by their tests. There are three primary terms used to indicate the results of your tests: hit, partial and miss. The value of 54% comes from a calculation of hit / ( hits + partial + miss) = coverage.

  • A hit is a line (aka statement) that is fully executed by your tests.
  • A partial is a statement (typically a branch) that is not fully executed. Example if true:... will always be a partial hit because the branch was never skipped because true is always true.
  • A miss is a statement that was not executed by tests.

A grade of 54%, in simple terms, says "Half my code is tested". Use Codecov to investigate methods and statements in your code that are not tested to help guide you on where to write your next test and increase the coverage.
