What is the meaning of Watir?

I have found that a lot of people say Watir is like Cucumber. I think this is confusing to people because Cucumber is a BDD tool and Watir is more in the realm of unit testing. I think it would help if people would just define what they mean by Cucumber and then differentiate between them.

Watir is a gem for Test-Driven Development (TDD) and Behavior-driven Development (BDD) that is based on a Ruby library called Selenium which in turn is based on the cross-platform web automation tools Selenium Remote Control (Selenium RC) and Selenium WebDriver. Watir, like Cucumber is a gem which helps you define tests in the language of the product you're testing. As you can imagine, this might seem a little overkill to most developers who are used to writing unit tests. So, after the release of Cucumber 1.2 in January 2023, many development teams moved from Cucumber to Watir. You can learn more about this here.

If you're thinking about using Selenium as your framework for testing your application, look no further than Cucumber. It's been proven to be an extremely effective tool for developing end-to-end applications. If you're interested in learning more about Cucumber, here's an article about why Cucumber was created and how it's a different type of testing paradigm.

Learn cucumber using Ruby. Watir is used for automating browser based tests. For example, you might use Watir to click a button in a website's login page. That might have been a scenario where you would have written something like:
Page.find("#loginbutton").click

While Watir lets you do that in an easier way. You will find many good examples in the selenium api book on github which describes how to use watir together with selenium api.e. Another alternative for automating browser based tests are selenium webdriver which automates chrome, firefox, and IE. There are also python bindings which can be used from python.

What are the uses of Watir?

The uses of Watir are a bit like those of HTML Tidy and Microsoft's Fakes, in that they all tend to be about making the lives of other people a bit easier. For me, the main areas of use are as follows: The first is testing. I don't think there's a good way to unit test a web browser, so I use Watir to help me do that. In many cases, I'll have a set of commands and a page that I need to work with, and with Watir, I can automate them together to make it very easy to do functional tests. So for example, I can click a link to get a form on a page, enter some data, click a button, etc. All of those things without me having to manually interact with my browser. Instead I can use a script.

The second is writing documentation. After a web application is being developed, it's a great time to test that you are documenting what is supposed to happen when the user clicks a particular button or submits a form. I find this is particularly useful for API-based applications as you can quickly test the input fields in your web server. But also for the web pages themselves, they are still very much a work in progress as they haven't been tested yet and you won't have access to all of the pages until they have. Testing whether your documentation is up to date is good for many reasons, and I'll cover some of those reasons here.

The third is teaching. It can be really hard to wrap your head around even a small portion of a full web application at first. It's really helpful for people to understand how different elements are structured, and there's often not a lot of existing documentation. There is a ton of good documentation out there for a lot of pieces of an application, but there's often just not enough of it. So I can look at a page that I think is easy to test with Watir and then put together a class that automates it with the knowledge I gained. I would say that's probably the most common use of Watir outside of testing, but the biggest drawback of course is that I can only create documentation for parts of the application that I can actually program.

How would you define writing documentation?
