I often have to run test cases on a site I work on. Most of the time I only need to check that an element exists on a site, or I have to scrape a bit of data of the site. Up until now I have been using Jsoup to do this work.
I have recently been introduced to Selenium Webdriver. I have been doing a bit of reading about it but am just trying to figure out when it is best to use it. In cases like mine, checking if an element exists on a page or scraping data I presume I would still be better off using Jsoup? And Selenium would be best suited for filling out forms and clicking buttons on a site?
Selenium has the advantage that it runs an actual browser, it will therefore execute all the JS and so forth in a way that's very, very close to an actual user of the site. The API further allows you to write your tests in a language that's close to the actual interactions (e.g. click to click on a link).
So if you do have tests that have some form of interactions (forms, links, etc.) The overhead of Selenium is worth it. If you simply want to open an URL and check for the existence of some content Jsoup will do.

I've looked for a solution for 2 days without getting any working answer. That's the point: I made a program which get information from the HTML of a website, needed to make some math calculation in order to resolve a captcha. I tried to make use of the output result with Selenium and everything seems to work perfectly (I handled all the popups, changes of the question and everything). But yesterday my output are not accepted anymore. The website says "Invalid security answer", while my answer it's correct. I think that the browser opened by Selenium has been someway detected but not blocked. So.. Are there any other working ways to write on a browser textbox the result I get from my java program? Or is there a way to try making the Selenium browser more "human"?
Thank you in advance!
P.S. I'm on Windows 10 with Chrome
Well, it is the whole point of CAPTCHA to check whether the user is a human or a computer.
Your question is proof that the CAPTCHA is working correct to seperate humans from computers, for more info: https://en.wikipedia.org/wiki/CAPTCHA

I am starting to build my first website with Angular&Bootstrap. I am using the Spring Tool Suite. So far my website looks pretty boring but learning CSS takes me a while.
On my website I have an input (style=file) and a button to submit. So far I managed to press a button to upload a file. I can see is as a String in the console when I log it, its working.
Now to the point where I need help:
I got a java-program that I have to use which gets the path to an XML-File and parses it. It checks if it has the right special format and reads it in. This is only a part of the whole program.
How can I use this in my Code to upload an XML-File and then check it and read it with this program? How do I use the Java-Code? So far I am only using HTML, CSS and Javascript.
Thank you for your help!
There are two options precisely available for you:
1) convert the logic which is in Java to Java script
Or
2) make it a web application and run it on tomcat(or a similar web server)
There are others too but there are a bit heavy to understand and implement.

I want to scrape my website and then use the data from the website to populate elements in my app, my website has login pages and certain pages only open after the login has been done.
I started working with HtmlUnit as it is a headless browser and completed the custom api in a java IDE, later i tried to use the jar i generated from the java IDE and found that there are incompatibility issues with HtmlUnit and Android.
Can anyone propose a solution to this problem?
Edit :
Since no one actually answered this question I am currently going with a work around using android's native WebView, settings its Visibility to invisible and then using javascript interfacing to a Java object, I can inject JS code to scrape any data.
Use Jsoup library for such purpose. Very handy and easy to use.
Start with this answer and follow documents and other examples.
Either you contribute to HtmlUnit to produce a version of HtmlUnit not using the missing dependencies from Android.
Or you can use an alternative method like this one, as this seems to be the path someone else go before you.
If a real headless browser able to manage any recent web features, would exist, it would mean a team would have developed it and then invest much effort in it (in supporting existing and coming features) consistently.
Apart from Opera, Chrome, IE, and Firefox browsers, there is no such team.
I would point out Chromium (CEF) as the most open and actively supported cross language wise. Try Cef for java

I am not a Java pro. I need to enable my completed java applications to ONLINE-Versions. Kindly give me the simplest way.
I have tried to go the JSP and Servlet way, but seems exceedingly tiresome,there surely ought to be a direct way.
When you use a typical web application what do you think is happening? You're in a browser and it's displaying some pages. You click around and some server does some work, for example Amazon shows you a list of books you could buy, the server is passing data to the browser for it to display.
That's a big difference from your current Java Application where everything is happening in the same computer.
This split between the UI part of the application, in the Browser, and the server part that's doing the real business is one reason why Web programming is so different from simple Java programming.
Servlets and JSPs are the traditional Java way of doing things, but modern web apps make much greater use of JavaScript for all the UI and all the Java (or any other server technology) does is provide the data displayed by JavaScript.
Bottom line: Sorry, but there is a whole lot more to learn. My recommendation would be to grit your teeth and forget about what you've done so far and start studying JavaScript and HTML.

I was wondering the best method and language to use for combining individual links into one "link?"
i.e. Normally the links are separated one by one in an email so you have to click each link individually, now I want to have it so the links are combined into one, so the user doesn't have to click each individual link but rather a "link."
I am assuming by "link" you mean a URL. A URL is a locator for a single resource (eg. web page). Typically when clicked, a browser window opens and the requested resource is presented. It does not open multiple browser windows and present multiple resources by itself.
You may be able to solve the problem by creating a URL to a web page that contains javascript to open multiple browser windows/tabs, each with the appropriate URL/resource.
If they are activation links, then you could use AJAX on a single web page to iteratively request each of the URLs in turn.
