How can i click on Save button to save a downloaded file using protractor in IE.
This action changes the browser focus back to the OS and away from Protractor. I see 2 possible solutions:
Try to side-step this prompt by instructing the browser to download files to a specific location.
Configure the browser (in this case IE) to save the file automatically without prompting: IE example . With Chrome it is possible to set this as part of the browsers capabilities, maybe IE has something similar? (this would make the configuration more permanent)
