robot framework run from Jenkins using git repository - jenkins

I need to run my robot framework test cases from Jenkins. I have few questions
How to identify whether do I need to use windows or Shell (based on which machine Jenkins are running?)
I tried in both ways (windows and shell) but its failing. Below is the commands I used to run
robot -i [tag] file1.robot
Is there any other commands I need to add?
Please suggest how to run?

to your first point it depends on the node/agent you define in your
project, rather than on the machine Jenkins is running on, but i
suspect that it is the same thing in this case.
You also have to have other dependencies on this node/agent, such as robot etc.

Run a gitlab CI pipeline in Docker container

Absolute beginner in DevOps here. I have a Gitlab repo that I would like to build and run its tests in the Gitlab pipeline CI.
So far, I'm only testing locally on my machine with a specific runner. There's a lot information out there and I'm starting to get lost with what to use and how to use it.
How would I go about creating a container with the tools that I need ? (VS compiler, cmake, git, etc...)
My application contains an SDK that only works on windows, so I'm not sure building on another platform would work at all, so how do I select a windows based container?
How would I use that container in the yml file in gitlab so that I can build my solution and run my tests?
Any specific documentation links or suggestions are welcomed and appreciated.

you can install those tools before the pipeline script runs. I usually do this in before_script.
If there's large-ish packages that need to be installed on every pipeline run, I'd recommend that you make yourown image, with all the required build dependencies, push it to GitLab and then just use it as your job image.

If you're using gitlab.com - Windows runners are currently in beta, but available for use.
SaaS runners on Windows are in beta and shouldn’t be used for production workloads.
During this beta period, the shared runner quota for CI/CD minutes applies for groups and projects in the same manner as Linux runners. This may change when the beta period ends, as discussed in this related issue.
If you're self-hosting - setup your own runner on Windows.
How would I use that container in the yml file in gitlab so that I can build my solution and run my tests?
This really depends on:
previous parts (you're using GL.com / self hosted)
how your application is built
what infrastructure you have access to
What I'm trying to say is that I feel like I can't give you a good answer without quite some more information

How to start docker containers using shell commands in Jenkins

I'm trying to start two containers (each with different image) using Jenkins shell commands. I tried installing docker extension in Jenkins and/or setting docker in global configuration tools. I am also doing all this in a pipeline. After executing docker run... I'm getting Docker: not found error in Jenkins console output.
I am also having a hard time finding a guide on the internet that describes exactly what I wish to accomplish. If it is of any importance, I'm trying to start a Selenium Grid and a Selenium Chrome Node and then using maven (that is configured and works correctly) send a test suite on that node.
If u have any experience with something similiar to what I wish to accomplish, please share your thoughts as what the best approach is to this situation.
Cheers.
That's because docker images that you probably create within your pipeline cannot also run (become containers) within the pipeline environment, because that environment isn't designed to also host applications.
You need to find a hosting provider for your docker images (e.g. Azure or GCP). Once you set up the hosting part, you need to add a step to your pipeline to upload/push the image to that provider's docker registry or to the free public Docker Hub. Then, finally, add a step to your pipeline to send a command to your hosting, to download the image from whichever docker registry you chose, and to launch the image into a container (this last part of download and launch is covered by docker run). Only at that point you have a running app.
Good luck.
Somewhat relevant (maybe it'll help you understand how some of those things work):
Command docker build is comparable to the proces of producing an installer package such as MSI.
Docker image is comparable to an installation package (e.g. MSI).
Command docker run is comparable to running an installer package with the goal of installing an app. So, using same analogy, running an MSI installs an app.
Container is comparable to installed application. Just like an app, docker container can run or be in stopped state. This depends on the environment, which I referred to as "hosting" above.
Just like you can build an MSI package on one machine and run it on other machines, you build docker images on one machine (pipeline host, in your case), but you need to host them in environments that support that.

Using build system to run tests or interact with clusters

What is the purpose of projects like these below that use Bazel for things other than building software?
https://github.com/bazelbuild/rules_webtesting
https://github.com/bazelbuild/rules_k8s
Are they just conveniently providing environment for run command (as opposed to building portable executables) or am I missing something?
The best I can tell is that Bazel could be used to run only subset of E2E tests based on knowledge what changed.
Disclaimer: I have only cursory knowledge about k8s and docker.
Bazel isn't just used for building and testing, it can also deploy, as you've discovered with the rules in those projects.
The best I can tell is that Bazel could be used to run only subset of E2E tests based on knowledge what changed.
Correct, but also extend tests to deployments. If you've only changed a single string in your Go binary that's injected into an image, Bazel is able to use rules_k8s, rules_docker, and rules_go to:
incrementally and reproducibly rebuild the minimum set files to
build the new Go executable
create a new image layer containing the Go executable (without using Docker)
push the image to the registry
redeploy changed pod(s) into cluster
The notable thing is that if you didn't change the source file, Bazel will always create an image with the same digest due to its reproducibility. That means that you can now trust the deployment workflow to not redeploy/restart a pod even if you do a bazel run twice or more.
For more, check out this BazelCon 2017 talk: Using Bazel for Fast, Correct Docker Deployments w/ Databricks
Fun fact: you can also use bazel run to start a REPL for your build target, from 0.15.0 onwards. Haskell and Scala rules use this.

Service from sources inside Docker container

Short question: is it ok (aren't there any contradictions with Docker ideology) to compile and start application from sources inside Docker container?
Assume that I have some hypothetical application. Let it be Java web service built with Maven, located somewhere in GitHub. Specifics doesn't matter here.
But before starting this service, I need to set-up several config files with right parameters, known at deployment time. Right now I can build fully-preconfigured application package with a single maven command, passing all the necessary configurations at build command.
Now assume that I need to make it a Docker container and don't have time to refactor it somehow right now. So I have a plan: let my docker image have Maven and Git, ENTRYSCRIPT clones my Git repository, builds and starts the application, passing all the necessary parameters via environment.
Is it suitable plan, or it's just wrong?

jenkins tests with ranorex

I'm just getting started with Jenkins and I have a few doubts that must be silly, but I'm stuck at it.
After I build my project Jenkins save the build file in some specific path?
Using Ranorex for automation test, is it better to put my files locally on the server or push them to a repository?
Note: I just start tried to use this, at this moment I can check for changes at BitBucket, build the file, build the Ranorex test and run the test.
Jenkins is quite a versatile application that allows system setup to specific needs and requirements of the test project. So i'd say go with the way that seems most logical/easiest. It's kind of a learning process as well so you will be able to understand the working flow of Jenkins itself.
But to answer your 2 questions:
1) By build files i believe you mean the test reports? - For this I actually use the Jenkins UserContent folder. This requires the "Copy to slave" plugin to be installed. With this you will get an additional Post-build Action where you can specify the files that will be copied over to the UserContent folder. But don't forget to specify a common layout for the naming of report files through the Ranorex run parameters ("/rf"). The UserContent folder actually acts as a web server and you can directly link the URLs for email reports. (eg. "http://Jenkins-server.com/UserContent/Regression-Client-Test-#1.html")
2) This totally depends on the system setup. But i can give you an example on how our system is currently set up. So we have Jenkins which runs on a Linux machine. It is only used to manage and run the tests and the actual machine does not include the automation test project. Then we have the test machine which runs on Windows and holds the actual automation tests. This machine is connected to Jenkins through the Slave functionality. So basically when someone starts a test job Jenkins from the Linux machine sends a command to the slave to start the automated tests. When the test run has finished post-build actions take over and copy the report files from the Slave machine to the Linux machines UserContent folder.
Now when talking about the test project management. It's a good idea to use a gir repository which will add another layer of somewhat "security". But if you have a small team (or you are the only test developer) then there is no actual need for it. You just copy the project to the test machine to a specified folder whenever needed/updated and you are ready to run it.

Martin
