Download a file protractor test case

I am writting a protractor test case to download a file which can be of any type.

• Scenario: Download a file
• Step 1: Click on the Download Link
• Step 2: Check whether the file is downloaded or not

How do i check if the file is downloaded correctly or not?

I was able to achieve download testing with Chrome.

1. Follow this config setup: https://stackoverflow.com/a/26127745/511069

2. Create a function waitFileExists(fileAbsPath) and performs your expectations after the file is completely downloaded: https://stackoverflow.com/a/27031924/511069
