The ability for anyone inside our organization, or outside working remotely via Slack/Teams etc., can quickly create tests from scratch using simple drag & drop functionality within ZebraRunners UI; not requiring any coding skills at all! We have automated regression testing across many different platforms (Web / Mobile), including iOS apps - but we've only just begun experimenting wih other types of code bases such as NodeJS applications that are difficult without some level technical knowledge due to their complexity.
This has been really helpful so far because it allows us complete control over how much time each engineer spends manually creating these new endpoints.
