Test scenario coverage

In this Era of AI, for test cases writing you can use generative AI tool like Chat GPT , Gemini etc..

If you upload figma screen shot in these tools, they will give you detailed level test cases but your prompt should be very clear and precise, means you should know what output you want. 

My team has practically experience it and they save significant time for this. But yest we have to thoroughly review the AI output for sure  so you need to spend your time for review, but yes overall significant time you save. And one step ahead you can share this statics to your higher management.

Now for automation, you can use tool like Cursor AI which automate your test cases using your sigma, but yest you need to r&d for this and come to your project base conclusion.
