Guru Ram how to write test class for below controller
public class EC_CaseDetailController {
public String currentRecordId {get;set;}
public String parameterValue {get;set;}
public Case ca{get;set;}
public EC_CaseDetailController(ApexPages.StandardController controller) {
currentRecordId = ApexPages.CurrentPage().getparameters().get('id');
ca = [select Casenumber,
PRX_Entity__c,
PRX_Type_of_request__c,
Status,
CreatedDate,
ClosedDate,
PRX_Number_of_requests__c,
PRX_Partner_Customer_name__c,
ContactEmail,
PRX_Name__c,
PRX_Free_text_field__c,
PRX_Mobile_number__c from Case where id =: currentRecordId ];
parameterValue = ApexPages.CurrentPage().getparameters().get('nameParam');
}
}
public String currentRecordId {get;set;}
public String parameterValue {get;set;}
public Case ca{get;set;}
public EC_CaseDetailController(ApexPages.StandardController controller) {
currentRecordId = ApexPages.CurrentPage().getparameters().get('id');
ca = [select Casenumber,
PRX_Entity__c,
PRX_Type_of_request__c,
Status,
CreatedDate,
ClosedDate,
PRX_Number_of_requests__c,
PRX_Partner_Customer_name__c,
ContactEmail,
PRX_Name__c,
PRX_Free_text_field__c,
PRX_Mobile_number__c from Case where id =: currentRecordId ];
parameterValue = ApexPages.CurrentPage().getparameters().get('nameParam');
}
}
Please follow this code snippet,
@isTest private EC_CaseDetailControllerTest { @testsetup private static void setup() { // Create a case record like this, // Case caseRecord = new Case(PRX_Entity__c = 'Some Value', Status = 'Some Value'............); // insert Case; } private static testmethod void runTest() { Case caseRecord = [SELECT Id FROM Case LIMIT 1]; Test.setCurrentPage(Page.YOUR_PAGE_NAME); ApexPages.currentPage().getParameters().set('id', casRecord.Id); ApexPages.currentPage().getParameters().set('nameParam', 'SOME_VALUE'); ApexPages.StandardController sc = new ApexPages.StandardController(caseRecord); EC_CaseDetailController controller = new EC_CaseDetailController(sc); System.Assert(controller.ca <> NULL); } }This can be your Test Class. Although you have do some work on it.
- In setup() method, I have commented some code which can create a Case. As I am not awared of you r Object structure I woudl like to suggest you to create the Case by your hand with proper fields and propers values.
- Inside runtest() method I have written this... Test.setCurrentPage(Page.YOUR_PAGE_NAME); Please write the Visualforce API name instead of YOUR_PAGE_NAME which is calling this Extension class.
- In This line .... ApexPages.currentPage().getParameters().set('nameParam', 'SOME_VALUE'); Please put proper page parameter value instead of SOME_VALUE.
PLEASE REMBER : If these three things has not been done properly, this code will not only fail but also not be compiled.Feel free to comment if you are getting any problem to save/run this test class.

You write a test class for this the same way that you would any other:
- Set up some data for the Trigger to access (in this case it looks like case)
- Instantiate the controller -
- Execute a method/methods
- Verify the behaviour with asserts.
Please try below code
@isTest private class EC_CaseDetailControllerTest { static testMethod void testCaseExt() { Case cas = new Case(Status ='New', Priority = 'Medium', Origin = 'Email'); insert cas; ApexPages.currentPage().getparameters().put('id', cas.Id); ApexPages.StandardController sc = new ApexPages.StandardController(cas); EC_CaseDetailController cec = new EC_CaseDetailController(sc); } }Please follow below salesforce Best Practice for Test Classes :-
1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .
10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .
