Python 인터넷 Continuous Integration Testing For Flask with Jenkins Create a simple flask app

Continuous Integration Testing For Flask with Jenkins
Create a simple flask app
There is a minimal flask app app.py
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return 'Hello World!\n'
if __name__ == '__main__':
app.run()
Create a test case
Create a test file test.py
import unittest
from app import app
class TestHello(unittest.TestCase):
def setUp(self):
app.testing = True
self.app = app.test_client()
def test_hello(self):
rv = self.app.get('/')
self.assertEqual(rv.status, '200 OK')
self.assertEqual(rv.data, b'Hello World!\n')
if __name__ == '__main__':
unittest.main()
Now if we run python3 test.py, the test should pass.
Jenkinsfile
The Jenkinsfile is
pipeline {
agent { docker { image 'python:3.7.2' } }
stages {
stage('build') {
steps {
sh 'pip install flask
}
}
stage('test') {
steps {
sh 'python test.py'
}
}
}
}
Now we have a repository with three files:
- app.py
- test.py
- Jenkinsfile
Save it to github or other git server, suppose the git url is https://github.com/darkn3rd/webmf-python-flask.
Install Jenkins
The quickest way is to use a customized jenkins docker.
Suppose we have a Dockerfile
FROM jenkins/jenkins:alpine
ENV JENKINS_USER admin
ENV JENKINS_PASS admin
# Skip initial setup
ENV JAVA_OPTS -Djenkins.install.runSetupWizard=false
COPY plugins.txt /usr/share/jenkins/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/plugins.txt
USER root
RUN apk add docker
RUN apk add py-pip
RUN apk add python-dev libffi-dev openssl-dev gcc libc-dev make
RUN pip install docker-compose
and the plugins.txt

favorite

blueocean

gitlab-plugin
then execute
sudo docker build -t custom-jenkins .
After the image custom-jenkins is finished, run it with
# use user root other than default jenkins to avoid permission problem
# use docker on the host, because there is no docker daemon in a docker container
sudo docker run --user root \
-v /var/run/docker.sock:/var/run/docker.sock \
-p 8080:8080 -p 50000:50000 custom-jenkins
Open http://127.0.0.1:8080 in browser, and
- add a
PipelinewithDefinitionbeingPipeline script from SCM - set the
SCMtoGitwith urlhttps://github.com/darkn3rd/webmf-python-flask. - Save
Test Report
Jenkins supports to represent the test reports with the JUnit format in the Blue Ocean, so we should change the output of the test
if __name__ == '__main__':
import xmlrunner
runner = xmlrunner.XMLTestRunner(output='test-reports')
unittest.main(testRunner=runner)
and the Jenkinsfile
pipeline {
agent { docker { image 'python:3.7.2' } }
stages {
stage('build') {
steps {
sh 'pip install flask
}
}
stage('test') {
steps {
sh 'python test.py'
}
post {
always {junit 'test-reports/*.xml'}
}
}
}
}
