In the dynamic environment of startups, multitasking founders and core team members often manage multiple responsibilities, including testing product features without formal documentation, which can become unsustainable as the company grows. As customer feedback drives product development, the need for a structured approach to test case management becomes apparent, highlighting the value of Test Case Management Systems (TCMS) that centralize testing processes, results, and documentation. Tools such as TestLink, Squash TM, Kiwi TCMS, and TestRail offer solutions for startups to efficiently manage test cases, integrate with issue trackers, and improve testing productivity. Emphasizing the importance of having an organized system over manual tracking methods like spreadsheets, the text underscores the significance of adopting TCMS for startups to ensure scalable and effective quality assurance practices.
