Parallel Running Automation Solution with Docker, Jenkins and Zalenium
The document discusses a new parallel running automation solution utilizing Docker, Jenkins, and Zalenium, addressing the limitations of a previous setup with virtual machines. The new solution enhances scalability, reduces resource usage, and simplifies testing through containerization and on-demand browser capabilities. Key features include easy start-up with Docker Compose and support for dynamic scaling of testing nodes.
Parallel Running Automation Solution with Docker, Jenkins and Zalenium
- 1. Parallel Running AutomationSolution with Docker, Jenkins and Zalenium Andrada, Nelly, Emilian
- 2. Contents - Why theprevious solution is not good enough - The goals we’ve had when starting to think at a new solution - How new solution achieves the goals we’ve set - About Docker - Zalenium - Configuration and Demo - Challenges - Improvements & Feedback
- 3. Previous solution - Jenkinsinstalled on one machine and 3 virtual machines installed on a different machine - virtual machine = 1 node - tests where sent in parallel to each node - nr. of nodes = nr. of tests run in parallel Disadvantages: - difficult to set-up - parallelism was created by the number of virtual machines
- 4. Goals - parallelize testsand reduce the time needed for testing - reduce hardware resources - quick up & running solution & easy to scale up - allow developers to “jump in” and run tests whenever they need to
- 5. New solution - Jenkinsand slave nodes as containers - fast start: `docker-compose up` - scale up nodes very easy as necessary `docker-compose up --scale slave=n` - configure slave nodes with multiple executors and send multiple tests to same node in parallel - use Zalenium to open on demand browsers in docker containers
- 6. About Docker - asoftware containerization platform - a container is launched by running an image - a container is an alternative to virtual machine - an image is an executable package that includes everything needed to run an application--the code, a runtime, libraries, environment variables, a particular OS and configuration files - Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services
- 7. Containers vs. VirtualMachines
- 9. Zalenium vs. Seleniumgrid Challenges: Setting up selenium grid & maintaining is not very easy: ● Downloading and setting up all the dependencies for each node. ● Manually restarting the nodes in case of issues. ● Maintenance is expensive. ● Scalability issues.
- 10. Zalenium - a gridthat scales up and down dynamically - opens/close browser containers/nodes (docker-selenium) on demand - requested browser: Chrome/Firefox - requested browser: IE/Safari -> if configured, request to BrowserStack, SauceLabs - records video with the test - allows visual representation with opened containers
