Kumar k 27 Urgent - test class
I need help on creating test class for the below class. I have written test class but which is covering only 5%. Please help us to get 80% code coverage.
public class ccweb{
public String cn{get; set;}
public Case cc{get;set;}
public Case c{get;set;}
private final Case mycase;
public ccweb() {
}
public Case getCase() {
return mycase;
}
public ccweb(apexpages.StandardController controller){
this.cc = (Case)controller.getRecord();
cn = ApexPages.currentPage().getParameters().get('cn');
mycase = [Select id,caseNumber from Case where caseNumber=:cn];
}
public PageReference save() {
update mycase;
return page.ThankyouPage;
}
}
public class ccweb{
public String cn{get; set;}
public Case cc{get;set;}
public Case c{get;set;}
private final Case mycase;
public ccweb() {
}
public Case getCase() {
return mycase;
}
public ccweb(apexpages.StandardController controller){
this.cc = (Case)controller.getRecord();
cn = ApexPages.currentPage().getParameters().get('cn');
mycase = [Select id,caseNumber from Case where caseNumber=:cn];
}
public PageReference save() {
update mycase;
return page.ThankyouPage;
}
}
@isTest public class ccwebTest { public static testMethod void testccweb(){ //Insert test case Case tstCase1 = new Case( Status = 'New', Origin = 'Email', Type='Other' ); insert tstCase1; Case caseObj = [SELECT id, caseNumber FROM case WHERE id = : tstCase1.id]; System.debug('=== CaseNumber: ' +caseObj.CaseNumber); // Set the page reference to test the controller PageReference tpageRef1 = Page.ThankyouPage; Test.setCurrentPage(tpageRef1); // Set the required parameters ApexPages.currentPage().getParameters().put('cn', String.valueOf(caseObj.CaseNumber)); // Create new instance of controller and call the method ApexPages.StandardController sc = new ApexPages.StandardController(tstCase1); ccweb testccWeb1 = new ccweb(sc); // Call save Method PageReference pr0= testccWeb1.save(); // call getCase method Case c = testccWeb1.getCase(); // Call controller ccweb cb = new ccweb(); // Set variable c value cb.c = caseObj; } }I will recommend you to start using trailhead to learn about test classes

Pleasse check below post sample test class
1) http://amitsalesforce.blogspot.com/2015/06/best-practice-for-test-classes-sample.html
You write a test class for this the same way that you would any other:
- Set up some data for the controller to access (Case)
- Instantiate the controller -
- Execute a method/methods
- Verify the behaviour with asserts.
Sample test class to start
@isTest public class ccwebTest { public static testMethod void testccweb() { Case csObj = new Case(); csObj.Status = 'New'; csObj.Origin = 'Email'; csObj.Type='Other'; csObj.Priority = 'Medium'; insert csObj; System.assert(csObj.id != null); Case caseObj = [ SELECT id, CaseNumber FROM case WHERE id = :csObj.id ]; ApexPages.currentPage().getParameters().put('cn', String.valueOf(caseObj.CaseNumber)); ApexPages.StandardController sc = new ApexPages.StandardController(csObj); ccweb obj = new ccweb(sc); obj.save(); Case testCase = obj.getCase(); System.assert(testCase != null); System.assertEquals(obj.cn ,caseObj.CaseNumber); } }NOTE:- Dnt forget to add assert. Without assert you will get code coverage only. but as per best practice you should add assert
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 .
