JavaScript is used by about 98% of web users, so by testing without it
enabled, we're only testing that the application works for a very
reduced number of users.
We proceeded this way in the past because CONSUL started using Rails 4.2
and truncating the database between JavaScript tests with database
cleaner, which made these tests terribly slow.
When we upgraded to Rails 5.1 and introduced system tests, we started
using database transactions in JavaScript tests, making these tests much
faster. So now we can use JavaScript tests everywhere without critically
slowing down our test suite.
ChromeDriver only supports characters in the BMP (Basic Multilingual
Plane). One test fails with ChromeDriver because it was entering emojis.
I'm using kanji characters instead, although I must admit I'm not sure
why such an unusual login was used in the first place.
