In one of my tests I am expecting some kind of DOM change. However, the page it's on is quite long.
So what I usually do for smaller components is to use screen.debug() method. But since the file is quite long, I started to also run the test task with DEBUG_PRINT_LIMIT=50000. Now that eventually got the result I got.
But that made me wonder, is it perhaps possible to save the output in a file?
According to the docs, screen.debug is essentially a shortcut for console.log(prettyDOM()).
So you could just use prettyDOM() directly, and do whatever with the result.
I would do copy(prettyDOM()) to put it on the clipboard and then paste it in a text file manually (in Chrome) or save it into a file (in node).

I need to provide text information in a file, read it in java-script and then work with the output. The output is not supposed to go to a web page, but is a plugin for another program (RPG Maker MV).
I'm trying to load a text-file (*.txt) and output it with document.write() I'm currently checking the code in Firefox. I get why this is prevented from working, but ultimately I do not want to run it in a Browser anyway. However I need to try the code before implementing it.
My text file looks like this:
What is the Capital of France?
-Berlin
-Paris [X]
-Koppenhagen
Who came up with the Theory of Evolution?
-Charles Darwin [X]
-Thomas Eddison
-Nicolas Flamel
The java-script should do something like:
var mytext=fs.readFileSync('quiz.txt');
document.write(mytext);
I could also use other file types than *.txt of course. Important is, that the quiz-file can be adapted without messing with the original java-script file.
Unfortunately, you can't use the same code to read in file in NodeJS and from code running in a browser as they use very different APIs.
NodeJS relies on the fs module while the browser environment relies on the File APIs specified by W3C.
I have a program that logs every GET/POST request made by a website during the page load process. I want to go through these requests one by one, execute them, and then determine if the file that was returned is a Javascript. Given that it won't have a .js ending (because of scripts like this, yanked from google.com a minute ago), how can I parse the file gotten from the request and identify if it is a Javascript file?
Thanks!
EDIT:
It is better to get a false positive than a false negative. That is, I would rather have some non-JS included in the JS-list than cut some real JS from the list.
The javascript link that you referred does not have a content type, nor does it have the js extension.
Any text file can be considered javascript if it can get executed which can make detection from scratch very difficult. There are two methods that come to mind.
Run a linter on the file contents. If the error is a syntax error or a Parsing error, it is not javascript. If there are no syntax error or parsing error, it should be considered javascript
Parse the AST (Abstract syntax tree) for the file contents. A javascript file would parse without errors. There should be a number of AST libraries available. I haven't worked with JS AST, so can't recommend any one of them but a quick search should give you some options.
I am not sure but probably a linter would also run AST before doing syntax checks. In this case, running AST seems like a lighter option.
The easiest way would be to check if there was anything identifying javascript files by their URI, because the alternatives are a lot heavier. But since you said this isn't an option, you can always check the syntax of the contents of each file using some heuristic tool. You can also check the response headers for its content-type.
My script adds some annotations to each page on a site, and it needs a few MBs of static JSON data to know what kind of annotations to put where.
Right now I'm including it with just var data = { ... } as part of the script but that's really awkward to maintain and edit.
Are there any better ways to do it?
I can only think of two choices:
Keep it embedded in your script, but to keep maintainable(few megabytes means your editor might not like it much), you put it in another file. And add a compilation step to your workflow to concatenate it. Since you are adding a compilation you can also uglify your script so it might be slightly faster to download for the first time.
Get it dynamically using jsonp. Put it on your webserver, amazon s3 or even better, a CDN. Make sure it will be server cachable and gzipped so it won't slow down the client network by getting downloaded on every page! This solution will work better if you want to update your data regularly, but not your script(I think tampermonkey doesn't support auto updates).
My bet would would definetly be to use special storage functions provided by tampermonkey: GM_getValue, GM_setValue, GM_deleteValue. You can store your objects there as long as needed.
Just download the data from your server once at the first run. If its just for your own use - you can even simply insert all the data directly to a variable from console or use temporary textarea, and have script save that value by GM_setValue.
This way you can even optimize the speed of your script by having unrelated objects stored in different GM variables.
So, I'm running these Selenium IDE tests against a site I'm working on. Everything about the tests themselves is running fine, except I would like to do a bit of clean-up once I'm done. In my MVC3 Razor based site, I have a JavaScript file with a function that gets a JsonResult from a Controller of mine. That Controller handles the database clean-up that Selenium IDE otherwise couldn't handle.
However, I'm having a hard time finding any sort of documentation on how to do this. I know I can do JavaScript{ myJavascriptGoesHere } as one of the Values for a line in the test, but I can't seem to find a way to tell it to go find my clean-up function.
Is it even possible for Selenium IDE to do this sort of thing?
If it comes down to it, I can just make a separate View to handle the clean-up, but I'd really like to avoid that if possible.
Thanks!
If you want to execute your own JavaScript function that exists in your test page from Selenium IDE, you need to make sure you access it via the window object. If you look at the reference for storeEval for instance, it says:
Note that, by default, the snippet will run in the context of the
"selenium" object itself, so this will refer to the Selenium object.
Use window to refer to the window of your application, e.g.
window.document.getElementById('foo')
So if you have your own function e.g. myFunc(). You need to refer to it as window.myFunc().
This can be very handy for exercising client-side validation without actually submitting the form, e.g. if you want to test a variety of invalid and valid form field values.
If you use runScript, that should already run in the window's context.
This works for me.
IJavaScriptExecutor js = driver as IJavaScriptExecutor;
string title = (string)js.ExecuteScript("myJavascriptGoesHere");
Make sure your javascript works first before using it here!
Actually to access your page javascript space, you need to get the real window of your page : this.browserbot.getUserWindow()
See this statement to get the jQuery entry point in your page (if it has jQuery of course ^^ )

I try to get to a page straight from Bash at http://www.ocwconsortium.org/. The page appears when you write mathematics to the field at the top right corner. I tested
open http://www.ocwconsortium.org/#mathematics
but it leads to the main page. It is clearly some javascript thing. How can I get the results straight from Bash on the first page?
[Clarification]
Let's take an example. I have the following lines for a Math search engine in .bashrc:
alias mathundergradsearch='/Users/user/bin/mathundergraduate'
Things in a separate file:
#!/bin/sh
q=$1
w=$2
e=$3
r=$4
t=$5
open "http://www.google.com/cse?cx=007883453237583604479%3A1qd7hky6khe&ie=UTF-8&q=$q+$w+$e+$r+$t&hl=en"
Now, I want something similar to the example. The difference is that the other site contains javascript or something that does not allow me to see the parameters. How could I know where to put the search parameters as I cannot see the details?
open "http://www.ocwconsortium.org/index.php?q=mathematics&option=com_coursefinder&uss=1&l=&s=&Itemid=166&b.x=0&b.y=0&b=search"
You need quotes because the URL contains characters the shell considers to be special.
The Links web browser more or less runs from the commandline (like lynx) and supports basic javascript.
Even though the title of the post sounds general, your question is very specific. It's unclear to me what you're trying to achieve in the end. Clearly you can access sites that rely heavily on javascript (else you wouldn't be able to post your question here), so I'm sure that you can open the mentioned site in a normal browser.
If you just want to execute javascript from the commandline (as the title suggests), it's easy if you're running bash via cygwin. You just call cscript.exe and provide a .js scriptname of what you wish to execute.
I didn't get anything handled by JavaScript - it just took me to
http://www.ocwconsortium.org/index.php?q=mathematics&option=com_coursefinder&uss=1&l=&s=&Itemid=166&b.x=0&b.y=0&b=search
Replacing mathematics (right after q=) should work. You may be able to strip out some of that query string, but I tried a couple of things and and it didn't play nice.
Don't forget to encode your query for URLs.
You will need to parse the response, find the URL that is being opened via JavaScript and then open that URL.
