Appium Philosophy


from http://appium.io/ Appium philosophy has four tenets -

  1. Application under test should not have to be modified to be able to run automated tests
  2. Automated tests should not be tied to one framework or programming language
  3. A mobile automation framework shouldn't reinvent the wheel when it comes to automation APIs.
  4. A mobile automation framework should be open source, in spirit and practice as well as in name!

Appium meets its philosophy in following ways -
  1. Appium satisfies its first Philosophy by using vendor-provided automation frameworks to control device. Hence Appium-specific or third-party code or frameworks do not have to be compiled with app under test. Hence you are testing same app which would be shipped. The vendor-provided frameworks Appium uses are:
     

  1. Appium satisfies its second philosophy by wrapping the vendor-provided frameworks in one API, the WebDriver API. WebDriver specifies JSON Wire Protocol which is a client-server protocol. Hence a client written in any language can be used to send the appropriate HTTP requests to the server. WebDriver supports clients written in many popular programming languages. Hence you are free to use whichever test framework you want. for example JUnit or Testng with java, NUnit with C#, PHP unit with PHP etc; The client libraries are HTTP clients and can be mixed into your code any way you want. Hence like, WebDriver, Appium is also not a “test frameworks" but rather an "automation libraries". And it is left to you how you want to write tests.

  1. Appium satisfies third philosophy by using WebDriver. Web driver has become the de facto standard for web browsers automation and is a W3C Working Draft. Appium  extended the protocol with extra API methods useful for mobile automation.

  1. Appium satisfies its fourth philosophy by being open source :-)

Using chrome console to test xPath and css selectors

Since the advent of selenium there have been many plugin to test xPath / css selectors but you don’t need any of them if you have chrome browser. Using Chrome console you can test both xPath and css selectors. Launch website to be tested in chrome browser and hit F-12 and you would see chrome console opened in lower pane of application - Hit escape key and console would open another pane to write element locators - And now you can start writing xPath or css selectors in chrome console and test them - The syntax for writing css id - $$(“ ”) And hit the enter key. If your expression is right then html snippet of the application element corresponding to the css selector would be displayed - If you mouse over the html snippet in chrome console then it would highlight the corresponding element in application - If you want to clean console of previously written element selectors then just hit ctrl+L keys and chrome console would be empty again.

Verify email confirmation using Selenium

Email confirmation seems to be integral part of any registration process. I came across an application which lets you provide your email address. You can follow the sign up link in you mail and then complete the registration process. Lets consider we provide GMail address for it. Now if were to use only Selenium then we would have to follow following steps - Launch GMail using Selenium; Some how search for new mail in the list of available mails; Some how click on it; Parse the mail message; Get the registration link; Follow up with registration process What do you think of an approach in which you can

Return only first or last element from webelements collection

We often come across situation when there are multiple elements on a page and we probably like to exercise only a few of them using selenium webdriver. May be just first and last element. For example on a search result page we may like to click on only first and last link and not all. This is when Iterables API comes handy. (By the way I am assuming that you have already completed watching selenium training videos :)). Once we have collection of web element then we can use Iterables to get only first or last element as following - Consider that we fetch collection of element as - List< WebElement > webElements = getDriver().findElements(By. id ( "htmlID" ));   Now we can get the first web element from this collection as -  WebElement firstElement = Iterables. getFirst (webElements,  getDriver().findElement(By. id ( "defaultElement" )));   Herein second argument -   (getDriver().findElement(By. id ( "defaultElement" )))    in the me
