Parameterize browser tests to execute them for Edge browser #671
Browse files Browse the repository at this point in the history 
Browser tests were only executed for the default configuration of a
system's browser using the SWT.NONE flag. Other configurations, such as
using the Edge browser in Windows, were not tested.

This change parameterizes the browser tests to also execute them for the
Edge browser on Windows. It also deactivates those tests for the Edge
browser for which the implementation does (currently) not work. This
allows to detect regressions when performing future changes to the Edge
browser.

Fixes
#671
