Lindo makes Rails testing easier
Lindo is a new Ruby gem we've released that makes Rails testing easier. If you're a regular user of
assert_select (or rspec's
have_tagequivalent) you probably find yourself frequently doing something like this when the assertion is failing and you can't figure out why:
def test_something post :something raise @response.body.inspect assert_select "div[id=header]" end
Inspecting the response body usually leads to a solution, but it can be tedious parsing through the huge amount of HTML that gets returned, often in a semi-unreadable format. Enter Lindo:
gem install lindo
Lindo adds a
vr method to your functional and integration tests. When this method is called, the response body is automatically opened in the default browser allowing for easy visual inspection of the page’s content:
post :new vr
If you’d prefer to jump straight to the source code, passing the
:html symbol will open the formatted HTML in the default text editor:
post :new vr :html
This has saved us a lot of time figuring out why a specific assertion is failing. Instead of parsing through the HTML, we can view the entire page and immediately tell if something is missing or out of place. We often call
vr even before writing assertions.
After installing, check out the README file for additional documentation. There is also a GitHub project if you’d like to contribute a patch or fork the code.
