What is the Best Way to learn SELENIUM?

-


I continuously see newbie questions like: "How I do I learn Selenium?", with little or no other context given.

So first... a clarification:
Selenium WebDriver is a system for automating browser interaction. It is accessed via programming library/API. If you want to use it without touching code, it is not possible (record/replay/export-madness via IDE aside). You can abstract away most of the programming aspects with higher level frameworks, but at that point you are no longer really dealing with Selenium anymore.

Selenium (WebDriver) provides language bindings and a similar API for several programming languages. It gives you a programming library that can manipulate a browser and web elements/controls.
You can't "learn" a library for a programming language if you don't know the language itself (syntax, idioms, etc).

So, my question to you: Which programming language are you going to use Selenium with? If you define that, someone can surely help point you in the right direction.

How are your programming skills? Which language do you want to learn in? If you know several, switching is trivial down the line, as the API's are similar between languages.

If you don't have skills in any Selenium supported programming language (java, c#, python, ruby, php, etc), then learn one of those before you even touch Selenium.

Selenium is a very small piece and once you know any of the programming languages well, you will find that its just like any other automation tool

Focus on JAVA(if that's your preferred choice of language ):

  1. OOPS : Encapsulation, Abstraction, Polymorphism, Inheritance.
  2. Introduction to class, Instance Variables, Instance methods, Class Variables, Class methods, Object.
  3. Constructors, Abstract methods, Abstract class, Interface (Multiple inheritance), Method overloading, Method Overriding, Packages.You definitely know when to create a class or Interface, how to initialize your instance variables(Non static).
  4. Control Statements:To be able to make decisions in test methods, Should I continue test execution,If login fails.
  5. Loops : Login into 5 different account using same methods.
  6. Arrays: No need to write variables all over test scrips.
  7. Exception Handling : How to continue with test execution if something unexpected happens during the test execution.
  8. Files and Streams: In case u want to keep test data out of your java source file,but how would u access them in your test scripts.( Parameterisation in Selenium)
  9. Collection framework.
  10. Multi-threading.

Happy Learning !

Explain public static void main in Java

Whether the class contains main method or not and whether main method is declared according to requirement or not these things won’t be checked by compiler. At Run time JVM is responsible to check these things. If JVM unable to find main method then we will get run time exception saying “No SuchMethodError: main” class Test { } Javac Test.java Java Test Runtime Exception: “No SuchMethodError: main” At Run time JVM always searches for the main method with the following prototype. public static void main (String[] args) public : public keyword is an access modifier which represents visibility, it means it is visible to all. To call by JVM from anywhere. This makes the main method public that means that we can call the method from outside the class. static : static is a keyword, if we declare any method as static, it is known as static method. The core advantage of static method is that there is no need to create object to invoke the static method. The main me

Reserve or Key Words in Java

Any programming language reserves some words to represent functionalities defined by that language. These words are called Reserved words. These words can't be used as names for Variables, Methods, Class or any other Identifier. Keywords for Data Types (8): 1. byte 2. short 3. int 4. long 5. float 6. double 7. boolean 8. char Keywords for Flow control (11): 1. if 2. else 3. switch 4. case 5. default 6. while 7. do 8. for 9. break 10. continue 11. return Keywords for Modifiers (11): 1. public 2. private 3. protected 4. static 5. final 6. abstract 7. synchronized 8. native 9. strictfp (came in 1.2 version) 10. transient 11. volatile Keywords for Exceptional Handling (6): 1. try 2. catch 3. finally 4. throw 5. throws 6. assert (came in 1.4 version) Keywords for Class Related (6): 1. class 2. interface 3. extends 4. implements 5. package 6. import Keywords for Object Related (4

OOPs concepts in Java with Examples

Object Oriented programming is a programming style which is associated with the concepts like  Class Object Inheritance Encapsulation Abstraction Polymorphism It's based on the concept of “objects” that contain data and methods. It works on the principle that objects are the most important part of your program.  It allows users to create the OBJECTS that they want and then create METHODS to handle those objects.  Manipulating these objects to get results is the goal of Object Oriented Programming. Simula is considered as the first object-oriented programming language. Smalltalk is considered as the first truly object-oriented programming language. Programming languages can be classified into 3 primary types: A. Unstructured Programming Languages: The most primitive of all programming languages having sequentially flow of control. Code is repeated through out the program B. Structured Programming Languages: Has non-sequentially flow of control. Use of
