Automated testing for CNC company

about company 

Partnet acts as a marketplace for industry, supplying everything from plastic molds to metal parts. It simplifies the interaction between factories and their suppliers, ensuring that production needs are met efficiently and on time. 

before 

Before our expert joined the project, the development team had already created many manual and unit tests. The product functioned in production with minimal bugs. However, there was still a need for sufficient test documentation. 

challenges and solutions 

The main task of our specialist was the automation of existing test scenarios, in particular, smoke tests and regression tests. He also worked on refactoring and maintaining these scripts. While working on the project, some challenges related to its unique features arose. And we are happy to share this experience with you. 

technologies, tools, and approaches 

To automate testing, our specialist used a list of technologies, each of which played a key role in the process: 

• JavaScript: Served as the main programming language, which made it possible to create flexible test scripts to test functionality. 
• Cypress: Used for efficient end-to-end testing, which significantly increased the speed and quality of tests. 
• GitHub: Acted as a version control tool, offering secure code storage and team collaboration. 
• CircleCI: Employed  to automate the CI/CD routine, which ensured continuous testing and quick detection of bugs in the code before releases. 

features of the project 

Our specialist proposed the creation of a traceability matrix, a powerful tool for ensuring high-quality testing. A traceability matrix is used to accurately map the relationships between business requirements and test scenarios, ensuring that every aspect of the system is subject to detailed analysis. This tool allows you to systematize the process of checking the compliance of the developed functionality with the stated requirements and identify parts not covered by testing, which is extremely important for ensuring the integrity and safety of the product. 

The traceability matrix is a critical document in software development, often misunderstood as insignificant. However, its role in the project cannot be underestimated: 

• Ensuring project integrity: It is key in tracking requirements from initial concepts to final tests. 
• Improved communication: Ensures a clear understanding of the relationships between tasks for all project participants, from managers to developers. 
• Risk Minimization: Helps identify and address gaps in testing, reducing the likelihood of a defective product being released. 

This matrix not only facilitates a detailed analysis of the requirements but also guarantees the quality and safety of the final product. 

results 

• More than 100 test cases were created, which helped to identify and eliminate potential problems before they occurred in real conditions. 
• More than 50 test cases were automated, which significantly improved the efficiency of the testing process, reducing the time to release product updates while ensuring a high level of quality. 
• The development of the traceability matrix allowed the client to track the relationships between requirements, test cases, and defects, which provided greater transparency and control over the development process. 
• Regression testing ensured that new changes or additions to the product did not break existing functionality.
