How much java is required for selenium testing
How much java is required for selenium testing? This question is always in the minds of professionals who would like to learn selenium, but are not so comfortable with too much of programming to learn. In this post, we will take a detailed look at the extent of Java to be learnt for Selenium scripting. The good news is that, it is not much.
This means that it is advisable to learn java for selenium as it will also help in improving your career prospects.
NOTE: Python is another language which is gaining some ground as an alternative to Java. Learn more about the Python selenium training program from Techcanvass.
Java language and programming for Selenium
Java is a vast language. However, You don’t need to learn full features of Java as that’s not required for selenium automation testing. You only need to learn a selected portion of Java language. That’s a good news.
There is always an apprehension and fear amongst non-programmers, about learning any programming language. We have noticed that programming term itself is scaring away many professionals from entering into automation testing. This has led to many competent testing professionals shying away from Selenium and automation testing. The reasons for these apprehensions are:
a) The programming sounds to be a little geeky and there is a general impression that not every one can be programmers. It requires some special skills.
b) Many graduates (Non engineering) feel that only Engineers can be programmers. That discourages, otherwise talented and capable, graduates from even thinking of entering this promising field of automation testing from scratch.
This is something which we come across every day when talking to people calling us for various courses.
Java required for selenium
So how much java is required to learn selenium? Let’s try and look at the broad topics, you need to master for selenium. This is also the order, in which we recommend to our students as well. This makes it little easier to learn.
Structure and essentials of Java program – You need to understand, what are the key components of every Java program. This structure is important. Next you need to understand the development environment, compilation and running of the program
Concepts of variables – People find it difficult to understand this concept when they start. Need a little effort to learn that.
Language structures like If-else, While, For loop etc – These are java language essentials and help in building logic
Classes and Objects – Learn the concept of classes and objects. At this juncture, it becomes really important. But don’t try and learn it in the beginning.
Arrays – How do we handle multiple data sets in Java? Arrays enables us in doing that. This is required because typically you will be using multiple test data sets for testing an application or screen.
Collections – Collections help in managing datasets in more efficient manner than arrays. Set, List & map are three types of collections, you need to learn.
Handling Files – Another important topic for Java. For writing your automation scripts, you will pick up data from files as well (typically Excel and CSV). So you need to know how to open and create files, read data from the files etc.
So, if we consider complete Java language set and APIs, this is only about 15-20% of complete Java. Moreover, the approach to learning can make a big difference too. Our approach to help you learn Java is detailed out in the article –
It’s important to follow the sequence in which you will be learning the above topics. This makes a lot of difference. Some of the conceptual topics in Java can really be confusing, if not learnt with the correct approach. This is one of the reasons, why many leave it mid-way.
