RE: [Htmlunit-user] htmlunit and sessions

[Rares Portan/SPR/RO <rp...@sa...>]

Hello Dan, thank for the feedback.
The bean was just an example, but there are other cases(like when the page 
requested by the user may be Page1 if some server conditions are meet, or 
Page2 otherwise)
that depend on "invisible" session attributes.

Anyway I know now what HtmlUnit can do and cannot do, it;s a great tool, 
but I still need the other tests.
So because others may need the same thing I'm sharing with them how I do 
test my session objects also using only HtmlUnit.

I've created a new servlet - named TestServlet :) - that will be used only 
for my tests. 
When you need to know a server side object value,  create a request to 
this servlet passing these string parameters:
1) the object name - used by session.getAttribute("objectName") to get the 
object from session.
2) the method name - the method that will be invoked using reflection on 
the object retrieved from session
3) the method parameters - parameters used to invoke the method( hint: 
name parameters P0,P1,P2.. to find them easy) 

The response of the invoked method will be "converted"  to string and send 
back as html something like this: <textarea>method_response</textarea>. 
I can use then HtmlUnit to parse the response and create my assert stuff.

Thanks

(I am not a Htmlunit veteran, so someone else feel free to correct me)
 
That is not what HtmlUnit is for.  You cannot access server side 
variables.  You can check their values though, if the variables are ever 
used to fill the values of a page (either a form default value or a text 
display).  Similar to what I suggested in my last email, you have to make 
a page that displays the value of that bean, and then check against that. 
Usually, this already exists!  For instance, since this is a login bean, 
does the next page show the login name somewhere?  (i.e. "hello JoUser") 
Then you could wrap that username in a span tag and say:
 
(pseudocode obviously)
 
var name = "JoUser"
HtmlUnit.setValueInForm(name, formElement)
HtmlUnit.submitForm()
HtmlUnit.getNewPageThatShowsUsername()
AssertEquals(HtmlUnit.getNameElementInNewPage().asText(), name)
 
Since the value on the page comes from the bean, if it matches what you 
put in the form than the bean was set successfully.  You could also create 
a test page that prints out all of the session object values and then use 
that for testing all of you bean submit comparisons.
 
You might also want to look into using Cactus for these tests, as that is 
a server side unit testing tool.  HtmlUnit is made for black box testing 
of web apps on the Web tier.

Hi, 

I have some objects kept in session, for example let say I have a 
LoginBean that has a username field. 
This object is updated when the form is submitted with the username 
entered by user in the textfield. 
And the bean is then used by the middlelayer to get the username. 
This data is not saved in the database, is just kept in session to 
identify the user. 

What I want is to compare the bean.getUsername() value with the value set 
in the textfield. 
This is just an example, the problem is that I have some session objects 
that are updated all the time based on user actions 
and I feel that I can't make complete tests for my application without 
testing them. 


HtmlForm form=.. 
HtmlInput username=.. 
String newValue="MyNewValue"; 

//update the field value 
username.setValueAttribute(newValue); 

//submit the form 
form.submit(); 

//get object from session 
LoginBean bean=session.getAttribute("LoginBean"); 

assertEquals(newValue,bean.getUsername());

I'm not sure exactly what you mean by "access to the session". Could you 
give an
example?
