I've just seen this issue on rails' issue tracker:
https://github.com/rails/rails/issues/2667
And I'd like to find out which parts of the code aren't covered. I couldn't find a coverage tool into the Rakefiles, and searching for it is a bit frustrating, since it returns far more results about test coverage on your rails app than test coverage of the framework itself.
Has anybody set up a code coverage tool? Is there any documentation on how to do it?
Rcov (or SimpleCov for 1.9) is the standard tool for Ruby code coverage. It should be fairly straightforward to get one of these to run the rails tests.

I am new in Karate but know almost all the basics. I want to generate a report for my test cases which will be kept in the folder for history purposes. currently, I am using the HTML report which overrides or updates every time I run my test cases.
If you can recommend me a step-by-step tutorial or a link, or simply give me a hint on how to approach this.
I have tried to use the allure framework and I am struggling to set it up.
Thought it would be the best approach to solve my problem.
Attached is my HTML report I am talking about. Thanks in advance
The JUnit HTML report which you have referred to as an image is designed for easy development, so when working on a test, you re-run and re-fresh the browser.
What we recommend is to use the parallel runner reports. Most of the time, 3rd party frameworks will solve this problem for you - especially if you use them integrated with CI. See this for example.
But finally, Karate will output the industry-standard Cucumber JSON report format, so you can always write a reporting solution yourself. Note that others have had success integrating Allure - so please refer this answer: https://stackoverflow.com/a/54527955/143475
We are using simplecov as our code coverage tool and it's great. One thing that would make it even better would be an output saying which file changes caused the drop in the coverage.
One possible way would be to store .resultset.json files and compare them with the newest results. Any other ideas? Has anyone done something similar?
I am using theIntern for unit testing my javascript framework. My test is running fine using node.
However, I am not able to generate code coverage report properly. I tried the options provided in the documentation. I was successful to print code coverage information on to the console while testing through selenium web driver. That gives only a summary.
How can I generate extensive code coverage report using reporters other than console?
I provided the "reporters" option but doesn't print the report. Any help would be appreciated.
The lcov reporter generates an lcov.info file that can then be passed to the lcov genhtml utility to output a complete set of HTML coverage reports (the simplest invocation is just genhtml lcov.info).
In Intern 1.2, however, there is a bug with the generated lcov.info files (fixed for Intern 1.3) that may cause genhtml to fail to find any coverage data inside a generated lcov.info file. The patch for this issue is very simple and you should be able to cleanly it to Intern 1.2 until the new version is released in the next couple of weeks.
Recently I started using BullseyeCoverage.
I'm going through the steps: compiling with BullseyeCoverage, running some test cases on the binaries created, generating a coverage report.
In the coverage report there are: function coverage, and condition/decision coverage. However, there is no line coverage. I tried to find a way of generating line coverage statistics, unsuccessfully. I thought of using covbr to this end, but, I need something that will cover all of my sources altogether.
Thanks for your help!
Bullseye does not support line coverage (which is also called statement coverage).For reasons, see http://www.bullseye.com/statementCoverage.html
I need a tool which measures test coverage under Ruby.
I tried rcov, but couldn't install it under Windows, Cygwin, or Ubuntu.
Which programs (not necessarily free) calculate the branch and/or line coverage of tests in Ruby and work with Ruby on Rails?
Simplecov. Rcov doesn't work so well under Ruby 1.9.*, but simplecov does.
You also have deep-cover which aims to be more complete than the mentioned examples.
From the Readme:
Deep Cover aims to be the best coverage tool for Ruby code:
more accurate line coverage
branch coverage
can be used as a drop-in replacement for the built-in Coverage library.
Use Ruby's built in Coverage feature if you are wanting something very simple. It is what Simplecov uses under the hood.
