What is the idea?
The core idea is based on two techniques and lots of ideas:
- The first one is the Page-Object Model, that provides a way to make tests more maintainable.
- The second one is the "record but not replay", that allows people without programming skills generate automated regression tests in an easier and faster way.
No one technique is mandatory, but the first one is strongly recommended.
We still have to much work to do (as you can see further below, in this very document), but, if you want, you can fork it and have fun!
It's STRONGLY recommended to not use it for commercial projects just yet, because it will change too much and we never tested it in a real project. We recommend you use it to emulate a project and, if possible, send us your example to be added on our library.
The way we chose to test our framework was... writing tests with it! This way we keep a stable version of it, and we can overcome the limitations of writing new features to cover the tests that weren't working and build a library of examples to future users.
So, this way, if you are not a developer, but an awesome QA with a little experience with code, you can help us by exploring this tool a little bit in your free time, and we will try make you happy fixing the bugs and implementing the new features you end up suggesting by writing great tests. These examples will be stored on our repository with your author credentials.
cello, you are going to need Bundler
$ git clone email@example.com:camiloribeiro/cello.git $ cd cello $ bundle install $ rake
The last step is launching the regression tests and all should be green.
If you have any problems, please let us know.
To use it you will need the development environment described in this document. Then you can follow the
bugbang example inside the
Soon I will provide more use descriptions :)
X-Platform: It does not matter if you are a Apple fan, A linux hard user or a windows geek. You can use it ;)
X-Browser Running: You can create different browsers to different tests, and can use it in parallel
Agnostic approach: You can choose between classical script, BDD, Object Oriented tests and hybrid tests to structure your tests. Also there is not a particular BDD tool to use it.
Restricted and unrestricted interface: By nature, you can do only do what an user can do, example: It is not possível to access non visible/enabled elements. Also can use the common Watir common interface to access them if necessary, therefore, it is not recommended.
Easy DSL: You will be able to create your DSL soon, but for while you have a simple DSL to work with.
Rspec asserssion: Even without a mandatody Rspec approach, you can use the 'should/should_not' assertions in your testings
DSL: Based framework that consists on a metaprogramming way to create customized test methods to each single project using a new DSL to provide test methods in execution time using only one line description for each element.
Selenium: Change Watir-webdriver to Selenium
Gem: Create the cello gem that will:
Get a page and write the elements in the page
DDT: Data driven testing by nature
