Show metrics on Travis-CI - travis-ci

Is is possible to configure Travis-CI t show metrics like SonarQube provides (http://nemo.sonarqube.org/) like
% duplicate lines
% code coverage
% rules appliance
% documented methods
etc
and see it graphically?
Thanks in advance. Guillermo.

I did not come across such setting. For Travis CI it would mean running scanners, which are highly dependent on the used by the project technologies.
However http://container-solutions.com/moved-ci-jenkins-travis/ explains how you can get SonarQube commenting code changes in GitHub pull requests.

Visual reporting for Karate without Jenkins CI

I'm trying to get reporting working for Karate DSL, and it's proven a challenge because my team uses Circle CI instead of Jenkins. Cucumber reporting seems to only work for Jenkins.
I've had a look at this documentation, here:
https://github.com/intuit/karate/tree/master/karate-demo#example-report
https://github.com/jenkinsci/cucumber-reports-plugin
I was wondering if there is a circle friendly equivalent you could recommend? It'd be even better if the reports could be generated in the terminal. It's going to be a hard sell to convince my team to change CI tools just so I can implement a test framework.
Thanks!
Here's what I suggest:
If you follow the demo / doc instructions - you will get the HTML reports in say target/cucumber-html-reports, and this is "pure Maven and Java", no dependency on CircleCI at all so far.
Now all you need to do is somehow make these HTML reports accessible via the web. In Jenkins, there is an HTML Publisher Plugin. I am not familiar with CircleCI but a quick search suggests that there is a way to expose links to build artifacts.
Also note that when you follow the demo, Java JUnit XML reports would also be output to target/cucumber-reports. It looks like CircleCI has support for these which means that it should be able to derive the build pass/fail status and stats if configured right.
Also note that Karate now enables you to write custom reports: https://stackoverflow.com/a/66773839/143475

Extracting SonarQube Report (preferably for Jenkins)

apologies if this has been covered, there have been a couple similar questions on SE - but struggling to find an explicit solution:
Does anyone know how to access the reports from SonarQube? I want to put some logic in Jenkins that will only proceed to do more stuff if quality gates are passed. This is something I wish to automate, and not login to sonarqube manually.
I have seen references to a possible, Gerrit plugin solution or using a curl step to use the API but neither explained how to replicate that approach.
You've got to use the SonarQube Scanner for Jenkins.
Specifically, check the "Analyzing in a Jenkins pipeline" section: it allows you to run a SonarQube analysis, and wait for the Quality Gate to be available so that you can decide (in your pipeline script) what to do based on the status of the quality gate.
sonarqube reports can be extracted using webapi
for example : http://sonarserver:9010/api/issues/search?componentKeys=sonarProject&severities=BLOCKER,CRITICAL,MAJOR,MINOR,INFO&s=SEVERITY&asc=false&ps=100
convert the json output to csv and to xls using online tools

How can I share source code across many nodes in a Jenkins pipeline job?

I have a build that's currently using the old build flow plugin that I'm trying to convert to pipeline.
This build can be massively parallelized (many units of work can run on many different nodes) but we only want to extract the source code once at the beginning, preferably with the Pipeline script from SCM option. I'm at a loss to understand how I can share the source extract (which apparently is on the master) with all of the "downstream" nodes that will be used by the pipeline script.
For build flow we extracted to a well-known location on a shared file system and all of the downstream jobs invoked by the flow were passed (or could derive) that location. That always felt icky & I was hoping that pipeline would have solved this problem but I can't find anything to suggest that it has. What am I missing?
I believe the official recommendation for this is to make bundles of the source and then use "stash" and "unstash" to make them available to deeper steps of your pipeline script.
See https://www.cloudbees.com/blog/parallelism-and-distributed-builds-jenkins
Keep in mind that this doesn't do anything to help with line-endings. If you have builds that span OSs with different line endings you either need to make OS-specific stashes, or just checkout to a safe label in each downstream step.
After further research it seems like the External Workspace Manager Plugin does what I'm looking for.

Publish Test Coverage Report Through Jenkins to Slack

I'm calculating code coverage on every build done in Jenkins and producing a coverage XML report. That's recorded really nicely inside of Jenkins with Cobertura, but what I'd really like is to be able to somehow get at the total branch coverage number so I can automatically publish to a medium the rest of my team can easily consume (i.e. Slack).
As a bonus, getting the difference in coverage from the last run would be even better. I don't see any environment variables that hold this, and haven't found anything detailing a simple way to do this in Cobertura docs. I know I can hack some code together to do this myself, but if there's a simple way I'm missing or something someone else has already built, I'd much rather do that.
I believe you'll have to do this yourself.
The existing Slack plugin just sends build start/success/failure notifications etc.
The Cobertura plugin unfortunately doesn't seem to be built on top of the static code analysis plugin, so there probably isn't much in the way of graphs, difference reports and all that.
You could try adding /api/json to the end of a Cobertura report URL for a Jenkins build — most endpoints reveal some information in this way. If there's some useful information, that could be a basis for whatever you want to hack together.

continuous integration for many languages

I want to setup a continous integration system that upon a commit or similar trigger should:
run tests on a fortran/C/C++ code, if needed.
compile that code using cmake.
run tests on a rails app.
compile the rails ap.
restart the server.
I'm looking at Jenkins. Is it the best choice for this kind of work? Also, what's the difference between using a bash script that makes all that (if possible) and using jenkins? I'm asking not because I'm thinking about using a script, but to better understand jenkins.
It sounds like Jenkins would certainly be a reasonable choice for this. Apart from the ability to run arbitrary scripts as build steps, there's also a large number of plugins, which provide better integration with cmake for example.
Even if you're using a single bash script to do all of this, using Jenkins on top of it would still have a number of advantages. You get a web interface, email notifications and build history for free, with all that this entails. By integrating your tests "properly" with Jenkins, you can also get things like graphs that show how many tests succeeded/failed over time.
I am using Jenkins for java projects and have to say it is easy to configure. I used to add lots of plugins for better configuration of build steps, but tend to go back to using scripting languages for build and deploy steps because of two main reasons. If I have a build script, it's easier to configure the same job on a different Jenkins server or run the script manually if need be and the build configuration is not so cluttered (I still have one maven job with more than 50 post build steps). The second reason is, that it is easier to version the scripts in SVN, compared to having the build config in SVN.
So to answer your questions. I don't know if it is the 'best' tool, but it is good enough for me. Regarding scripting: use each tool for what it is build for. Jenkins a glorified cron deamon with great options when it comes to displaying analysis. The learning curve for people to use it is minimal (i.e. starting a job, seeing whether it failed.) Configuring Jenkins needs a little bit more learning, but it's very easy to set up simple jobs and go then to the more complicated tasks.
For the first four activities Jenkins will do the job and is rather the best choice nowadays, but for things like restarting the server (which is actually "remote execution"), better have a look at:

Libraries like Fabric(Python) or Capistrano(Ruby) might be useful too.
