Implementation
Overview
The primary objective of the project is to explore the usage of Cucumber for test automation in Java, particularly focusing on REST APIs. Facing challenges with manual testing, our aim was to streamline testing processes, improve reliability, and enhance overall efficiency.
Mastering Cucumber allows Numino Labs to deliver faster, more reliable software through efficient test automation and fosters clearer communication with clients by using easily understandable test scenarios.

01 Dependency Installation and Environment Configuration
We installed necessary dependencies and configured the test environment to support Cucumber implementation in Java. Log4j was utilized to implement logging functionality, ensuring comprehensive logging for test execution and debugging purposes.
02 Test Case Identification and Scenario Creation
During the test case identification phase, existing manual test cases were used to create scenarios for automation using Cucumber's Behavior-Driven Development (BDD) approach. We created feature files using Gherkin syntax to outline test scenarios in a clear and concise manner, with a keen focus on user-centric behavior. This approach not only facilitated collaboration among team members but also ensured that our tests remained closely aligned with the intended functionality.
03 Test Data Management
For test data creation, we leveraged Cucumber annotations to execute SQL scripts, ensuring that each test scenario had access to the necessary data for execution. This streamlined the testing process and helped maintain consistency in our test environment.
04 Organization and Documentation
In terms of organization and documentation, we utilized tags as annotations within our feature files to categorize scenarios based on their nature or functionality. This enabled easy filtering and selective execution of specific sets of scenarios, enhancing our test suite's manageability. Additionally, we employed the natural language format of Cucumber tests, coupled with inline comments and feature-level documentation, to ensure that our tests remained self-explanatory and comprehensible to all stakeholders involved in the development process. This approach promoted transparency
05 REST API Validation
Thorough validation of REST API responses was conducted using various criteria, including status code checks, response comparison, and custom checks. This comprehensive validation process ensured the correctness and integrity of the API responses, contributing to the overall quality of our software products.
06 Step Definitions Implementation
To complete our implementation, we implemented step definitions in Java to translate Gherkin scenarios into executable test steps, ensuring seamless integration with our test framework.
07 Integration with GitLab CI/CD Pipeline
Finally, we integrated our Java-Cucumber tests with the GitLab CI/CD pipeline, enabling automated execution upon code commits or merges. This integration facilitated continuous testing and safeguarded against regressions, ensuring the reliability of our software delivery pipeline.
Outcomes
12 APIs Automated
Testing procedures for 12 APIs, including functionalities such as image uploading, CSV and PDF export, and Auth token handling, were automated.
Total 103 Test Cases Automated
Demonstrating comprehensive coverage achieved through the automation of test cases across various API functionalities.
Test Execution Time
Approximately 10-12 minutes are required to execute all the test cases, showcasing the efficiency gained through automation.

Cons
Steep Learning Curve
Cucumber's syntax and concepts may present a steep learning curve for team members unfamiliar with BDD or Gherkin syntax, potentially leading to slower adoption and initial productivity dips.
Overhead in Maintenance
While Cucumber promotes reusability through feature files and step definitions, maintaining these artifacts can become cumbersome as the project scales. Keeping feature files up-to-date and managing step definitions may require significant effort.
Complexity in Debugging
Understanding and debugging Cucumber tests, especially when dealing with complex scenarios or integration issues, can be challenging. Identifying the root cause of failures may require deeper knowledge of Cucumber's inner workings.
Language Requirement
Cucumber's step definitions are coded, requiring familiarity with the chosen programming language. This could be a barrier in environments where this language isn't commonly used, making test implementation and maintenance more challenging.
