Building and Packaging Code

Dependecny Managment

• To develop any application , there will be lots of dependencies on other libraries/sdks
• before building/packaging we need to download these dependencies
  • nodejs npm
  • python pip
  • .net nuget
  • java mvn

Test Executions

• We would be running
  • unit tests (test code by writing code) => developers
  • integration tests
    • unit test
    • ui test
    • api test
  • Functional tests
    • ui tests (simulate user) => selenium, cypress, qtp…
    • api tests (postman, rest assured)
  • Performance tests:
    • load testing harness (jmeter, load runner)
• What we should know for ci/cd
  • command to invoke tests
  • where will be test results
  • converting test results to some common formats (junit xml)

Java Based Applications

• To build Java Based applications, we have many tools
  • ANT
  • Maven
  • Gradle
• In this case we will be using a maven based java application
  • JDK = 17
  • MVN 3 +
  • Project: Refer Here
• Manual steps

sudo apt update
sudo apt install openjdk-17-jdk maven -y
git clone https://github.com/spring-projects/spring-petclinic.git
cd spring-petclinic
mvn package # creates package, run unit tests
