Hi!
We heavily use AI for writing visual regression tests, but unfortunately not in the TestComplete IDE, because, as mentioned earlier, their IDE has become obsolete. We use Cursor (but it also works with VS Code + Copilot).
TC projects are written in JavaScript, so we can add extensions like ESLint for better code analysis. There's also an unofficial TestComplete extension that provides access to all the engine's specific methods (aqstring, aqobject, etc.), so we can have IntelliSense within the IDE. Git management is also much better. Namemapping hasn't been used for years; we prefer to use Find with a component repository (we use a POM architecture, which helps a lot).
If you have the application's source code available (accessible via Cursor or Copilot), they can easily generate tests that take into account the specifics of the agent.md file.
As a bonus, it even handles component identification automatically because it has access to the component IDs. We don't use much of TestComplete anymore besides the engine (we're still dependent on it because we have applications with WPF/Delphi/Web interoperability -_-' we're not perfect either :-D).
You can also launch TestExecute from VS Code via the command line, but you won't have access to debugging.
