[SalesForce] ApexPages.currentPage().getParameters in ApexComponent and in Visualpage are different

I am trying to pass url parameters between Apexpages and component but am not successful in achieving this. When I call ApexPages.currentPage.getParameters().put('test','aaa')

in a pagecontroller and then call ApexPage.currentPage.getParameters().get('test') in a component controller which resides in that page. The method returns nothing. Can someone tell me how can I persist the url parameters between page controller and component controller?

thank you

I think your question was unclear. You said that the value needs to be pass from the page to controller.but if the value is dynamic then you have to workaround on <apex:param> tag.

If you are passing the parameters like ID then You have to append the URL of vf page with your ID and value like below

https://yourdomainname/apex/vfpagename?test=value

And get the parameter in the controller using

ApexPages.currentPage.getParameters().get('test');

Update:

Try the below link

Hope this might helps....

[SalesForce] Are there any difference in passing parameters to another page using pagereference.getparameter and manually generating querystring

They're the same, you will see any parameters added via addParameters in the URL as query parameters.

A more secure way to do it would be sharing a controller across Visualforce pages, in which case you wouldn't need to pass parameters between pages. However for this, I believe redirect needs to be false, or else it flushes the ViewState.

[SalesForce] How does one test Visualforce components with custom controllers

Testing a controller is independent of testing the component. That is, you test the controller by simulating the inputs to the controller's properties as if VF passed them to the controller . Thus, your testmethods need to set the controller properties.

So, your testmethod should look like

@isTest
public class TestCustomComponentController {
    public static testmethod void doTest () {
        Test.setCurrentPage(Page.ThePage);  // not really needed to test the component itself
        CustomComponentController cont = new CustomComponentController();
        cont.sObj = new Lead();   // simulate the assignTo operation on the apex:attribute
        System.assertEquals(cont.getRecType(), 'Lead');
    }
}

You don't need to put the component on a testpage to test the controller

BTW -- I'm a bit confused by the method getRecType() - it is returning the sObj as a string. SFDC recordTypes are a concept altogether different from sObjects so you might want to change your methodname
