4 min readTo mock a service in Kotlin, you can use libraries such as Mockito or MockK which provide functionalities for creating mock objects.

6 min readGit calculates line changes by comparing the contents of files before and after a commit and determining how many lines were added, removed, or modified. Git uses a technique called diffing to analyze the differences between the two versions of the files. This is done by comparing each line in the old version with the corresponding line in the new version to identify any changes. Git then categorizes these changes as added lines, removed lines, or modified lines.
