What are the stages in Jenkins?
A stage block contains a series of steps in a pipeline.
That is, the build, test, and deploy processes all come together in a stage.
Generally, a stage block is used to visualize the Jenkins pipeline process.
A step is nothing but a single task that executes a specific process at a defined time..
How do I run a test case in Jenkins?
Example of a Junit Test in JenkinsStep 1 − Go to the Jenkins dashboard and Click on the existing HelloWorld project and choose the Configure option.Step 2 − Browse to the section to Add a Build step and choose the option to Invoke Ant.Step 3 − Click on the Advanced button.More items…
What is Jenkins in simple words?
Jenkins is an open-source automation tool written in Java with plugins built for Continuous Integration purposes. Jenkins is used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build.
What is the use of Jenkins pipeline?
Jenkins Pipeline (or simply “Pipeline”) is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins. A continuous delivery pipeline is an automated expression of your process for getting software from version control right through to your users and customers.
How do I skip test cases in Jenkins?
skip=true — With this option maven compiles the tests but doesn’t launch them. So you may want to use the second option instead as fast code compile validation. E.G.: if you develop some library or module that will be used by some one else you must be sure that you don’t brake contract with the client.
How do I run a Jenkins job on a specific node?
Navigate to the configuration pages for the jobs that you want to run on this node and select the General tab. Select Restrict where this project can be run. In the Label Expression field, enter the label for the node where you want the job to run.
How do you run parallel test cases in Jenkins?
There are three ways you can run tests in parallel as part of a Jenkins build:Configure your tests to run in parallel following examples for your scripting language.Set up your Jenkins project as a Matrix Project.Configure your Jenkins build as a Parameterized Build.
Why your tests may pass locally but fails in Jenkins?
Since the Jenkins machine/VM/pod/container is likely running different (slower) hardware than your local machine, tests dealing with multiple threads or inadvertent race conditions may run differently and fail in Jenkins.
What are the different types of jobs in Jenkins?
Jenkins supports several different types of build jobs. The two most commonly-used are the freestyle builds and the Maven 2/3 builds. The freestyle projects allow you to configure just about any sort of build job: they are highly flexible and very configurable.
What are Jenkins agents?
Agent. An agent is typically a machine, or container, which connects to a Jenkins controller and executes tasks when directed by the controller. Artifact. An immutable file generated during a Build or Pipeline run which is archived onto the Jenkins Controller for later retrieval by users.
What is the difference between Jenkins job and pipeline?
The main difference between any job and a Pipeline Job is that the Pipeline Scripted job runs on the Jenkins master, using a lightweight executor expected to use very few resources in order to translate the pipeline to atomic commands that execute or send to the agents.
How do I run multiple jobs in parallel in Jenkins?
Go to your job -> configuration and check: Execute concurrent builds if necessary. Doc: If this option is checked, Jenkins will schedule and execute multiple builds concurrently (provided that you have sufficient executors and incoming build requests.)
Is Jenkins a CI or CD?
Jenkins is an open source automation server written in Java. It is used to continuously build and test software projects, enabling developers to set up a CI/CD environment. It also supports version control tools like Subversion, Git, Mercurial, and Maven.
How do you fail a stage in Jenkins pipeline?
You can even fail the build and continue the execution of the pipeline. Just make sure your Jenkins is up to date, since this is a fairly new feature. Stage takes a block now, so wrap the stage in try-catch. Try-catch inside the stage makes it succeed.
How do I get JUnit test report in Jenkins?
3) In Post-build Actions, click on Add post-build action, select “Publish JUnit test result report”. In Test report XMLs specify the directory where all your xml reports are getting generated. Eg : D:\Java\reports. Here specify the path as reports/*.
How do I trigger another job in Jenkins post build?
Use build job plugin for that task in order to trigger other jobs from jenkins file. You can add variety of logic to your execution such as parallel ,node and agents options and steps for triggering external jobs.
How do I run sequentially in Jenkins?
Many ‘phases’ can be set up as part of the MultiJob project and each phase “contains” one or more “other” Jenkins jobs. When the MultiJob project is run, the phases will be run sequentially. Therefore, in order to run N jobs sequentially, add N phases to your MultiJob project, and then add one job to each phase.
What is a Jenkins master?
The Jenkins master acts to schedule the jobs and assign slaves and send builds to slaves to execute the jobs. It will also monitor the slave state (offline or online) and getting back the build result responses from slaves and the display build results on the console output.
