Study Notes
Continuous Integration
- Involves building the code, which includes not just compilation, but also unit testing, integration testing, code review, and packaging.
- New functionality is continuously integrated with existing code, ensuring continuous development of software.
- Jenkins is a popular tool used for continuous integration, fetching committed code and preparing a build for testing or production servers.
Continuous Testing
- Involves continuously testing software for bugs using tools like TestNG, JUnit, Selenium, etc.
- Automation testing tools allow QAs to test multiple code-bases in parallel to ensure no flaws in functionality.
- Docker Containers can be used for simulating test environments.
Continuous Monitoring
- Records and processes important information about software usage to identify problem areas.
- Monitors system errors, resolves issues, and maintains security and availability of the service.
DevOps and Continuous Testing
- Continuous testing is a crucial process in the continuous delivery pipeline, along with continuous integration.
- Continuous testing involves executing automated tests repeatedly against the codebase in various deployment environments.
- Includes unit tests, static code analysis, security code analysis, integration tests, and load and performance tests.
Continuous Delivery
- Involves automated deployment pipeline, where code is continuously integrated and tested before release to production.
- Tools like Chef, Puppet, Ansible, and SaltStack are used for continuous deployment and configuration management.
Continuous Feedback
- Analyzes results from software operations to improve application development.
- Achieved through constant feedback between development and operations teams.
Continuous Deployment
- Deploys code to production servers, ensuring correct working in real environments.
- New code is deployed continuously, with configuration management tools executing tasks frequently and quickly.
Continuous Operations
- Based on complete automation of the release process, allowing organizations to accelerate time to market.
Learn about building every commit, including unit testing, integration testing, code review, and packaging using Jenkins for continuous integration. Understand the importance of continuously integrating new functionality with existing code to reflect changes to end-users.
