Coverage.py vs. Python vs. RPM Package Manager vs. hug Comparison Chart

Coverage.py is a tool for measuring code coverage of Python programs. It monitors your program, noting which parts of the code have been executed, then analyzes the source to identify code that could have been executed but was not. Coverage measurement is typically used to gauge the effectiveness of tests. It can show which parts of your code are being exercised by tests, and which are not. Use coverage run to run your test suite and gather data. However you normally run your test suite, and you can run your test runner under coverage. If your test runner command starts with “python”, just replace the initial “python” with “coverage run”. To limit coverage measurement to code in the current directory, and also find files that weren’t executed at all, add the source argument to your coverage command line. By default, it will measure line (statement) coverage. It can also measure branch coverage. It can tell you what tests ran which lines.

The RPM Package Manager (RPM) is a powerful package management system capable of building computer software from the source into easily distributable packages; installing, updating, and uninstalling packaged software; querying detailed information about the packaged software, whether installed or not; and verifying the integrity of packaged software and resulting software installation. The package’s metadata is stored in the RPM header. The header is a binary data structure that stores single pieces of data in tags. Each tag has a pre-defined meaning and data type. These are not stored in the header itself but need to be known by the code reading the header. In the header, the tags are only referred to by their number. Each tag is either of a plain scalar type or is an array of one of these types. While not enforced by the type system the RPM code assumes that tags belonging together have the same number of entries.
