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.
The test is failing on my machine sometimes. I thought it was because
`open_last_email` didn't wait fot the request generated by clicking the
"Registrarse" button to finish. Even if that might be the case, adding
an extra expectation showed the test was really failing because
invisible captcha reported the form was filled in too fast.
I wonder whether invisible captcha is working properly or there are
times where it doesn't start its timer when it should.
Since this might be a bug in the application, I'm not changing the test
just to make it pass.
We're improving the readability of the ones we're about to modify.
Using human texts makes tests easier to read and guarantees we're
testing from the user's point of view. For instance, if we write
`fill_in banner_target_url`, the test will pass even if the field has no
label associated to it. However, `fill_in "Link"` makes sure there's a
field with an associated label.
So tests won't fail when an institution changes the default organization
name.
The tests are also easier to understand now, since it's more obvious
where the "CONSUL" text is coming from.
We were repeating the same code over and over (with a few variants) to
setup tests which require an administrator. We can use a tag and
simplify the code.
