Parameterize browser tests to allow executing 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 allow executing them
for Edge browser on Windows. Due to current issues with the tests in the
CI, this change only adds the parameterization but does not add Edge as
a parameter yet.
