As the saying goes, “If you want something done right, you have to do it yourself.” The same can be said for build automation testing. If you want your tests to run smoothly and without any errors, you need to take care of the process yourself.
Jenkins is a great tool for automating builds, but it can be frustrating if you’re not familiar with its inner workings. If you’re not careful, you can easily end up with a lot of wasted time and effort.
One of the most common problems with Jenkins is that it can be very slow to run tests. This is often due to the fact that Jenkins tries to run all of the tests in parallel, which can lead to a lot of contention and slow down the process.
One way to solve this problem is to delay the execution of the tests until Jenkins has finished building the project. This can be done by adding a “post-build” step to your Jenkins job.
In the “post-build” step, you can add a shell script that will wait for the build to finish before running the tests. This will ensure that the tests are run in the correct order and that they don’t interfere with each other.
The shell script should look something like this:
while [ ! -f build.complete ]; do
This script will wait for the build.complete file to be created before running the tests. This file can be generated by the Jenkins job itself or by another process that signals the completion of the build.
Once the tests have been run, the results can be published to a central location so that they can be easily accessed by the team.
Jenkins is a powerful tool that can help to automate the build and testing process. However, it is important to understand how it works in order to get the most out of it. By taking the time to learn about Jenkins and how to use it effectively, you can save yourself a lot of time and effort in the long run.

How do I reduce the time taken for a build in Jenkins?
There are a few things you can do to reduce the time taken for a build in Jenkins:
1. Make sure you are using a fast build server.
2. Make sure your build is not doing anything unnecessary. For example, if you are building a Java project, make sure you are not doing a full clean build every time.
3. Use a build cache to store intermediate build results. This can speed up subsequent builds, as long as the build cache is not invalidated too often.
4. Use parallel builds to build different parts of the project in parallel. This can speed up the overall build time, as long as the build steps can be run in parallel without dependencies.
How can a build be scheduled in Jenkins?
There are two ways to schedule a build in Jenkins:
1. Through the web interface
2. Through the Jenkins CLI
How do you set a quiet period in Jenkins?
In the Jenkins interface, click on “Manage Jenkins” and then click on “Configure System”.
Scroll down to the “Silent Period” section and enter the number of seconds that you want Jenkins to wait before checking for new changes.
How do I schedule Jenkins to run every 15 minutes?
In the “Build Triggers” section of your job, select “Build periodically”.
In the “Schedule” field, enter “*/15 * * * *” (without the quotes).
