As answered by people managing Glitch and JIterator.
JIterator's answer:
Traffic as test cases, supporting automatic diff and automatic assert, eliminating the cost of data preparation and assert writing, achieving lower-cost automated testing.
JIterator's answer:
Automated traffic recording and replay technology revolutionizes testing efficiency and accuracy. Streamline your testing processes, shorten iteration cycles, and ensure continuous software quality improvement.
JIterator's answer:
Medium to large enterprises with the Java technology stack or small enterprises with special requirements for stability
JIterator's answer:
In 2015, to address the increasingly severe challenges of automated testing for Taobao's price calculation system, we developed a traffic testing tool suitable for Taobao's backend systems, inspired by Tcpcopy. With its help, the price calculation system has never had a failure since.
In 2016, we were tasked to support the largest reconstruction project in the history of Alibaba's transaction system: the middleware transformation project. To support core transactions, we improved the product and achieved fully automated Mock capabilities for downstream systems, ensuring the smooth implementation of the project. Later, recording and replay became the core safeguard for the transaction system.
As our reputation spread within the group, our product was adopted and used by more teams. By 2023, more than 7,000 systems had adopted the system for support and it had also supported hundreds of system reconstruction projects, including Ping An Bank externally.
Due to organizational strategy adjustments, the traffic testing tool no longer provides external services. We created JIterator to provide services to the public. It has also surpassed the original traffic testing tool in many aspects, surpassing its predecessor.
JIterator's answer:
