Testin

Testin云测 (Testin Cloud Testing) is a Chinese enterprise services platform founded in 2011 by Jiang Xiaohai, who spotted a pain point among mobile internet startups: the prohibitive cost of building in-house app testing teams . The company pioneered cloud-based app testing as a global first, starting with third-party testing services for internet companies and expanding into a broader platform covering security, promotion, and AI big data . By late 2018 it had served 2.9 million apps and built an enterprise client roster including China Merchants Bank, Mercedes-Benz, McDonald's, and State Grid . Gaorong Ventures led its Series B in 2015 and has since tracked its evolution from a testing specialist into what it frames as a full-cycle enterprise application service platform . In 2018 Testin made its A/B testing tool standard version free—a move that, as 极客公园 noted, signaled its strategic shift beyond the "cloud testing company" label toward a wider mission of "making applications more valuable" .
