Continuous Integration (CI) Testing is a crucial component of software development, ensuring quality and consistency by running automated tests during the build, packaging, and publishing phases. This process includes various tests, such as code quality, unit, integration, and security tests, to catch issues early and enhance confidence in software deployments. CI Testing allows for repeatability and rapid feedback, serving as quality gates that prevent progression if minimum quality standards are not met. It also distinguishes between on process and off process testing, where the former involves tests executed directly by the CI process and the latter involves external evaluations, such as container scanning. The use of CI tools like CircleCI and Jenkins facilitates this testing, and adopting a robust CI platform like Harness can further streamline the process by resolving dependencies and providing visibility into test coverage. As development practices evolve, the importance of an adaptable CI Testing framework becomes increasingly significant to support agile and microservices development, ensuring that software artifacts meet high-quality standards before deployment.
