What is ‘Pair Programming’?

Pair programming is an engineering practice where two programmers work on the same system, same design, and same code. They follow the rules of “Extreme Programming”. Here, one programmer is termed as “driver” while the other acts as “observer” which continuously monitors the project progress to identify any further problems.

Can you explain the architecture of Jenkins?

Jenkins follows the master-slave architecture. The master pulls the latest code from the GitHub repository whenever there is a commitment made to the code. The master requests slaves to perform operations like build, test and run and produce test case reports. This workload is distributed to all the slaves in a uniform manner.

Jenkins also uses multiple slaves because there might be chances that require different test case suites to be run for different environments once the code commits are done.

Explain the build process using CodeBuild in AWS DevOps.

First, CodeBuild will establish a temporary container used for computing. This is done based on the defined class for the build project.
Second, it will load the required runtime and pull the source code to the same.
After this, the commands are executed and the project is configured.
Next, the project is uploaded, along with the generated artifacts, and put into an S3 bucket.
At this point, the compute container is no longer needed, so users can get rid of it.
In the build stage, CodeBuild will publish the logs and outputs to CloudWatch Logs for the users to monitor.

Explain the implementation of Continuous Testing in DevOps?

By following the below-mentioned steps we can implement continuous testing in DevOps:

1. In DevOps continuous testing starts in the development phase, as the developer tests the functionality of the code by using tools like selenium.
2. Tools like GitHub store these tests and versions along with the software code. DevOps team uses these tests to perform testing on the new build of the software code.
3. when the code reaches pre-production, the professional QA team uses these tests by making some changes to the test specifications.
4. the operations team can reuse these tests for user acceptance testing and for resolving the post-delivery issues.
