What's the best choice to stress test a node.js powered server? I need to send a lot of single request and measure the delay time and validate the response. If possible I need to export data or generate graphics.
If you're willing to pay a little bit for the service, blitz.io can be a good way to go. Otherwise, apache benchmark is also a nice option, though you'll have to work a little harder for response validation and graphics.
A cluster of JMeter instances would do the trick. JMeter can export all the measurements and you can use Excel^H^H^H^H^Hyour favourite spreadsheet to do the graphics.
Try Vegeta. It focuses on making it easy to achieve a target rate of requests per second. I mean you can test your service's behavior at multiple requests per second. What about your report requirement, here you can also add -output flag which specifies the output file to which the binary results will be written to.

I want to be able to create a new html file that will be displayed and saved on the server for future use when a new user logs into their account. Can this be done using JavaScript or are there any libraries that I could get that would be able to do this?
This can be done through use of the fs module in node. See https://nodejs.org/api/fs.html.
However, it is very likely that this is not the best solution to the problem your solving. Instead of creating a new html file for every user, you probably want to save user details in a database and have a single html file that can be populated with the data when it's needed.
This is not possible with JavaScript alone unless you use Node.js. Otherwise will need PHP or a similar server-side language.
If you go that route, here is a nice tutorial that may be beneficial to you:

I explored the javascript unit test libraries ( qunit, jasmine ), but my requirement is run the unit test scripts based on the browser type on runtime.
that means, if i run the unit test scripts first i need to identify running browser type ( ex: chrome ) using the framework and run only related browser test cases.

There isn't a whole lot of information for me to go off of, but it seems that this post is similar.
To answer your question, Selenium can probably handle what you're looking for, but it will depend on your exact needs not specified in this post.
This one:

Seems to have an option for configuring the browser before run the test.
Hope is enough, haven't really tried it myself.

We have a webshop and we sell lots of items.
Our checkout process consists of 4 different pages where the user has to input their address, select a delivery method and confirm their order on different pages/urls. Each of those pages relies on communication with the server and lots of javascript / jquery.
Some of our users have reported problems at some parts of those pages. We suspect it could be a combination of OS/browser that can't understand a part of our javascript code.
Is there any way to automate testing of a checkout process of 4 different consecutive pages, each requiring user input?
We would like the testing environment to test on different brosers/browser versions.
We also had a customer recently that had an antivirus program that would change the urls of our js source files, is there any way to capture cases like that by testing?
Sounds like you might use E2E testing, using Protractor/Selenium.
It's basically about writing user behaviour, and the browser driver does it instead of user. You can write what should happen on the page and if any of these conditions is not met, it will be included in the post-test report. You can configure it to use whatever browser driver you like.
I suggest you to take a look at Selenium. The main purpose of it is to automate browsers actions.

Is there any web API that takes a URL and gives back the readable content of that page? Or is there any javascript library that can do this?
Installing node.js or any server-side app is not possible.
That's actually a really hard problem. Such questions usually imply that you want sidebars and similar 'noise' elements excluded. This is often solved with different training sets within the machine learning computer domain and it's not easy to develop.
Having said that - take a look at:
http://www.alchemyapi.com/api/scrape/
http://www.readability.com/developers/api
http://www.diffbot.com/
This should help you to learn enough about the space that you'll be able to do better searches for you problem domain.
I think you could find some related services on Mashape (http://www.mashape.com/).
Search for 'text'. Like this: https://www.mashape.com/search?query=text
There are several NLP / Analysis providers there, and most of them are freemium.
OTOH, there's also a project called boilerpipe. You can test its quality at the URL below:

we want to provide an online bookmark service to our customers. Therefor it would be nice to provide also a function to store local bookmarks into our online tool. This shouldn't be done automatically - the user should confirm this action (only in case someone thinks I want to spy users data).
I'm looking for a while now, but I found only that there is no solution, because it's a security risk. Is there a way or already a tool for such a functionality in Javascript?
Regards
This is completely impossible.
You need to write a browser addon.
Is there a way or already a tool for such a functionality in Javascript?
Nope, definitely not. Maybe for browser extensions - if it's possible even for them.
No there isn't any solution to do this via javascript. The only solution I can think of is to use a Java Applet to read the client's computer and look for the bookmark.
Another way is you can ask them to export their favorites to a file and upload to your website.
Prompt the user to upload the bookmarks file: http://productforums.google.com/forum/#!topic/chrome/i1r3CgqvgCI
