Hey @sushant_kadam , which stack that you use to write tests and manage. I think opens chatgpt and interact is the way to test E2E for ChatGPT Apps. In case you want to test prompt > render app, I think MCP Jam is a solution too.
Btw, I just launched the mcp-studio. Runs entirely locally, you can test your tool call with your expected arguments, interactive with widget UI, change the setting (display mode, dark/light theme, etc) and then record it as a test - similar to cypress but for ChatGPT Apps.
Just run npx @pragmalabs/mcp-studio
