First of all, we need to answer the question – why even do we need to learn JS?
In answering this question, we’ll indicate a few of the most important things:
- While testing software, one may learn its program code;
- Correct understanding of all the code features;
- To see the initial cause of defects in DevTools Console;
- To find work-around software defects;
- Automation of the testing process in a web browser;
- Ability to independently create auxiliary tools to facilitate the testing process;
- Optimizing the use of WebDriver JSExecutor;
- Just to navigate the mysterious and interesting discoveries that may surprise you while learning this language.
All this increases the capacities of high-quality software testing, and as a result – the user’s ability to interact with various programs and supporting applications.
So, if you’re a junior tester who wants to learn JS or management of your software testing company asks you to do that, you have to heed our advice.
Tip #1: Automation in a Web Browser
On the Internet, there are a lot of useful courses that demonstrate in practice how to correctly and efficiently learn to perform software testing with JS.
There are both paid and free material.
You have to puzzle out the language to understand it as a programmer who makes software.
Tip #4: Interpreting JS
Become familiar with Speaking JS. There is a lot of useful information and an extensive review of language syntax.
Tip #5: DOM Enlightenment
It would be useful to read such a course as DOM Enlightenment to have a more integrated understanding of how to use DOM. You will often do similar things performing automation in a web browser.
One should take into account this peculiarity, especially when there is a lot of program code that has to be supported. Moreover, this resource will be useful for the practical understanding of program code written by other developers.
Tip #7: Useful and Available Snippets
Try a special Google Chrome extension – Useful Snippets. A great benefit of this plug-in is the option to see the JS performance in the DevTools console when you’re running the command.
