Use Jenkins for continuous integration, this knowledge point must be mastered

Thank you for taking out

Jenkins is a commonly used continuous integration tool. I think everyone will use it more or less when doing automated testing. I don't know how you use Jenkins to trigger automation when you are doing UI automation testing.What about the test script?

01, Part one

Generally speaking, for beginners, Jenkins is usually installed on the local machine, and the code is also stored on the local machine or Git. No matter which storage method is used, it will eventually land on the local machine.Using Jenkins to trigger UI automation test scripts in this environment is actually very simple. You only need to create a Job and configure the trigger method in the Job. Let's take Python+Selenium as an example, such as

Build

02, Part two

But there is a problem. I don't know if you have encountered it. In actual work, Jenkins and the machine used to run automated tests are often not the same machine. For example, Jenkins is deployed on a Linux server, and UI automation tests are run on Windows entities.machine or Windows virtual machine, then the question is, how does Jenkins trigger this Windows machine to make the UI automation script run?

Here we need to understand the agent mechanism of Jenkins.

Jenkins architecture is designed for distributed build environments.It allows us to use a different environment for each build project to balance the workload among multiple agents running jobs in parallel.

The Jenkins controller is the original node in the Jenkins installation.The Jenkins controller manages the Jenkins agents and coordinates their jobs, including building Jobs on the agents and monitoring the agents.Agents can connect to the Jenkins controller using a local or cloud computer.

01, create Jenkins node

1. Click System Configuration, Click Node Management

System Configuration

Create node

Create node 2

2. Download the agent and save it to the specified directory of the remote machine

Download agent

3. The remote machine starts the agent (it should be noted that JDK must be installed and environment variables must be configured)

java -jar agent.jar -jnlpUrl https://qa.jenkins.com/computer/autotest_node/slave-agent.jnlp -secret b323s70ss08sbougs92f043fcfda9644hsns04snspbs

Start agent

02, Jenkins Job Configuration

General selects the running node of the restricted project, and selects the created node in the label expression

Finally, I would like to thank everyone who has read my article carefully. Watching the rise and attention of fans all the way, there is always a need for gifts. Although it is not a very valuable thing, if you can use it, you can take it directly.

These materials should be the most comprehensive and complete preparation warehouse for friends who do [software testing]. This warehouse has also accompanied me through the most difficult journey. I hope it can also help you!Everything should be done as early as possible, especially in the technology industry, and the technical foundation must be improved.Hope it will be helpful to you all...

If you don't want to experience the feeling that you can't find any information during self-study, no one answers your questions, and give up after a few days, you can join my QQ group below to discuss and exchange, there are also various softwareTest data and technical exchange.
