Changing consumer preferences and growing market demands have significantly impacted the software development life cycle. This translated into a rise in demand for faster innovation, leading to early product development, release, and time to market. Different SDLC phases had to accelerate their delivery mechanisms to meet the speed.
And here is where devops automation arrived as an advantage in accelerating and streamlining internal processes. The role of automation is widely discussed in software testing, referred to as ‘Test Automation’ and ‘Automation Testing.’
While ‘Automation Testing’ is a software technique that tests and compares the actual outcome with the expected outcome, Test Automation automates repetitive and other testing tasks that are tough to perform manually.
The continuous integration and continuous deployment (CI/CD) market is experiencing significant growth, with projections indicating it will surge to USD 45.8 billion by 2027, boasting a Compound Annual Growth Rate (CAGR) of 15.7%. According to the State of DevOps Report, this remarkable expansion is driven by the widespread adoption of CI/CD pipelines, with reports suggesting that 86% of organizations are either utilizing or planning to implement such pipelines.
Moreover, the advantages of CI/CD implementation are evident, particularly among high performing organizations, where 75% have fully embraced CI/CD pipelines compared to only 42% of low performing counterparts. These high performing entities report notable benefits, including 50% faster code deployment, 20% higher developer productivity, and a significant 70% failure reduction, as outlined in the XebiaLabs CI/CD Benchmark Report.
Leveraging DevOps automation consulting can further amplify these results by helping organizations design and implement optimized CI/CD strategies. CI/CD best practices play a crucial role in detecting bugs, automating repetitive tasks, improving execution speeds, and reducing the overall time required to test software. However, a successful CI/CD test automation process is a combination of automation and an effective testing strategy.

Determining Essential Testing Requirements
Determining what to test and how to approach automation in CI/CD pipelines is crucial for efficiency without compromising quality. While automating every test is impractical due to increased execution time, identifying critical unit and integration tests as part of a robust CI/CD testing strategy helps optimize testing efforts. Leveraging DevOps for automation plays a key role in streamlining these processes, ensuring that the right tests are prioritized without slowing down delivery. Unit testing, typically integrated into the CI portion of the continuous delivery pipeline, focuses on specific aspects of code functionality.
1) Entry and Exit Points
Unit tests validate the input and output of code, ensuring correct functionality. By testing individual code components, failures are minimized when the components are integrated.
2) Isolated Functionality
Functions operating independently, such as authentication or calculators in microservice architectures, can achieve 100% unit test coverage. They require no external dependencies, facilitating thorough testing.
3) Boundary Value Validations
Unit tests can comprehensively test code behavior with valid or invalid inputs. This approach avoids exhaustive manual testing by efficiently covering various scenarios.
4) Clear Data Permutations
Code handling precise data inputs and outputs is ideal for unit testing. Complex data scenarios are better addressed at the integration level due to potential challenges related to mocking and performance impact.
5) Security and Performance
While primarily tested at the integration level, unit tests can validate security and performance. Code should handle invalid authentication and injections and perform efficiently. Unit tests help ensure the robustness of individual code levels, contributing to the overall integrity of the system. In essence, strategic unit testing targets specific code components, enhancing reliability while minimizing redundancy in testing efforts.
