Build & Test (BT)
Design a strategy for running 500 unit tests in parallel across 5 build agents to reduce pipeline time. Specify the tool (e.g., Jenkins pipeline, GitHub Actions matrix) and the key configuration required to split the test execution effectively.
Explain the necessity of using an artifact repository (e.g., Nexus, Artifactory) in the build process. Describe the workflow for a successful build: from artifact creation to tagging, pushing to the repository, and subsequent consumption by the deployment stage.
Outline a strategy for automating API integration tests within the CI pipeline. Specify the ideal testing framework (e.g., Postman/Newman, Cypress), how the environment variables (e.g., API endpoint URL) should be securely injected, and the pass/fail metrics.
Clearly distinguish between Integration Testing and End-to-End (E2E) Testing. Provide a unique example test case that would be appropriate for each type within the context of an online booking system.
Compare the key features (scalability, pipeline language, cost model) of a cloud-native CI platform (e.g., GitHub Actions, GitLab CI) versus a self-hosted solution (e.g., Jenkins). Recommend the best option for a small, budget-conscious startup.
Outline 5 steps for securing and hardening a production Docker container image. Steps should include techniques like using minimal base images (e.g., Alpine), dropping root privileges, and running a container vulnerability scanner.
Explain the necessity of Test Environment Isolation (e.g., separate databases, network segmentation) for parallel CI pipeline runs. Describe a scenario where lack of isolation would lead to test flakiness and unreliable results.
Design a stage in the CI/CD pipeline dedicated to automated load/stress testing. Specify the tool (e.g., JMeter, Locust), the typical thresholds for failure (e.g., latency, error rate), and how to prevent this stage from blocking a critical production deployment.
Explain the concept of the Test Pyramid (Unit, Integration, E2E). Detail the recommended distribution of tests (e.g., 70% Unit) and justify why Unit Tests should form the base of the pyramid in a fast-moving DevOps environment.
Outline a strategy for ensuring the continuous availability and performance of External Dependencies (e.g., third-party APIs) during testing. Detail the use of mocking or service virtualization to isolate tests from external failures.
Distinguish clearly between Performance Testing and Load Testing. Provide an example objective for each type of test when assessing a newly developed microservice.
Outline a plan to automate the ephemeral provisioning of a temporary End-to-End Test Environment using IaC (e.g., Terraform/CloudFormation). This environment should be provisioned before the test run and automatically torn down immediately after completion to save costs.
Define the ideal purpose and configuration of a Staging Environment in the CD pipeline. Detail two ways the Staging environment should exactly mirror the Production environment (e.g., load balancer configuration) and one area where it can safely differ.
