Interview Questions
Cypress can be integrated with CI/CD pipelines using cypress run command, configuring environment variables, and proper pipeline setup. Common integrations include GitHub Actions, Jenkins, CircleCI, and GitLab CI. Example configuration includes installing dependencies, cache management, and artifact storage.
cypress open launches the Test Runner UI for interactive testing and debugging, while cypress run executes tests headlessly in the command line, suitable for CI/CD environments. cypress run provides additional options for CI integration like reporters and screenshot management.
Test reporting can be configured using built-in reporters (spec, junit, json) or custom reporters. Reports can be stored as artifacts, integrated with test management tools, and used for test result analysis. Configure reporter options in cypress.config.js or command line.
Environment variables control test behavior in different environments. They can be set through CI/CD platform, cypress.env.json, or command line arguments. Sensitive data should be stored as secure environment variables in CI/CD platform.
Test artifacts (screenshots, videos, reports) can be stored using CI/CD platform's artifact storage. Configure artifact paths in pipeline configuration, implement retention policies, and manage artifact access. Use for debugging failed tests.
Parallel test execution runs tests concurrently across multiple machines/containers to reduce execution time. Requires Cypress Dashboard or custom parallelization setup. Configure through CI/CD platform and proper test organization.
Test retries can be configured using retries option in cypress.config.js or command line. Helps handle flaky tests in CI/CD environment. Configure different retry strategies for run mode and open mode.
Cypress Dashboard provides test recording, parallel execution, failure analysis, and team collaboration features. Integrates with CI/CD for detailed test analytics and debugging. Requires projectId and record key configuration.
Test data can be managed through fixtures, database seeding, or API calls. Implement proper data cleanup, isolation between test runs, and environment-specific data handling. Consider using test data management tools.
Caching npm dependencies, Cypress binary, and build artifacts reduces pipeline execution time. Configure cache paths in CI/CD configuration, implement proper cache invalidation, and monitor cache effectiveness.
Cross-browser testing requires proper browser installation in CI environment, browser-specific configurations, and test execution across different browsers. Configure through cypress.config.js and CI/CD platform setup.
Test stabilization involves proper waiting strategies, retry mechanisms, and error handling. Implement proper test isolation, environment cleanup, and robust selector strategies. Monitor and analyze test failures.
Test notifications can be implemented through CI/CD platform integrations, custom reporting tools, or notification services. Configure failure notifications, status updates, and alert thresholds. Consider implementing detailed error reporting.
Test result analysis involves reviewing test reports, analyzing failure patterns, and monitoring trends. Implement proper result categorization, failure analysis tools, and trend monitoring. Consider using analytics platforms.
Environment management involves proper configuration, isolation, and cleanup between test runs. Implement environment-specific settings, data management, and resource cleanup. Consider using environment management tools.
Performance optimization includes parallel execution, proper resource management, and efficient test organization. Implement test splitting strategies, resource optimization, and execution time monitoring.
Test dependencies can be managed through proper package management, version control, and dependency caching. Implement dependency update strategies, vulnerability scanning, and dependency maintenance.
Test monitoring involves tracking execution times, failure rates, and performance metrics. Implement monitoring tools, metric collection, and performance dashboards. Consider using monitoring platforms.
Test security involves secure credential management, proper access control, and security scanning. Implement security best practices, vulnerability testing, and secure configuration management.
Large test suite management involves proper organization, execution strategies, and resource optimization. Implement test categorization, execution planning, and maintenance strategies.
Advanced parallel testing involves custom parallelization approaches, resource optimization, and execution coordination. Implement advanced splitting strategies, resource management, and execution monitoring.
Custom integrations involve developing specific integration points, automation scripts, and workflow customization. Implement custom plugins, integration tools, and workflow automation.
Advanced reporting involves custom report generation, data aggregation, and analysis tools. Implement comprehensive reporting frameworks, analysis systems, and visualization tools.
Test orchestration involves coordinating multiple test suites, environments, and execution flows. Implement advanced orchestration tools, workflow management, and execution coordination.
Advanced environment management involves sophisticated environment provisioning, configuration, and cleanup strategies. Implement advanced environment tools, configuration management, and resource optimization.
Custom infrastructure involves building specialized test environments, tools, and frameworks. Implement custom infrastructure components, management tools, and optimization strategies.
Advanced monitoring involves comprehensive system monitoring, analysis, and alerting. Implement sophisticated monitoring tools, analysis systems, and response strategies.
Custom automation frameworks involve developing specialized automation tools, workflows, and integrations. Implement custom framework components, automation tools, and workflow systems.
Advanced security testing involves comprehensive security analysis, vulnerability testing, and compliance verification. Implement advanced security tools, testing frameworks, and compliance monitoring.
Custom analytics involves developing specialized analysis tools, metrics collection, and visualization systems. Implement custom analytics platforms, data processing tools, and reporting systems.
