Running tests downloads an export file in the system's Downloads folder

[arielj]

Before we start...:

• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed
• I'm reporting the issue to the correct repository (for multi-repository projects)

Branch/Commit:

Main branch

Expected behavior:

Running tests shouldn't leave files somewhere else in the system

Actual behavior:

I think that, because a feature spec is downloading a file, the file is downloaded to the default download folder of the headless browser.

Steps to reproduce:

1. Step 1: Run tests
2. Step 2: Check the Downloads folder (or whatever is set as the download folder of firefox)

I will abide by the code of conduct
