ReactNative is a standard for mobile app development these days and TestComplete still doesn't support that. There exist some discussions in this forum that TesComplete might be support ReactNative but this is not true... I was discussing with TestComplete and they said that this is not possible. If TestComplete wants to be a competitive tool in mobile testing then ReactNative support is a must-have feature. Sadly but this is a huge obstacle for our company and we even thinking about switching to another testing tool... Other well known commercial testing frameworks support this but TestComplete is not. I strongly believe in this automation tool and I hope that Mobile Automation is the thing that you're planning to improve. Because it has always been a weak spot for TestComplete.
