The reason your test class is not saving is because you have explicitly defined a constructor in your main class as PrepareSandboxPostCopy_Batch(sObjectFieldsMap). Therefore you don't have access to the default constructor PrepareSandboxPostCopy_Batch() i.e. constructor without any params.

You will have to instantiate the class using this constructor in your test class PrepareSandboxPostCopy_Batch(sObjectFieldsMap).

  • Hello sir,Can you help me one more time please Using this code my Start method is calling but the second execution method in not calling can you help me Commented Jan 11, 2019 at 5:24

Your batch constructor override to accept parameter of type Map<String, List<String>>. So you need to pass sample input to that parameter. Update your testmethod as below.


Map<String, List<String>> sObjectFieldsMap = new Map<String, List<String>>();
sObjectFieldsMap.put('Account', new List<String>{'Name', 'BillingCity'}); //Add valid sObject and fields for code coverage 
sObjectFieldsMap.put('Contact', new List<String>{'Name', 'Email', 'Other_Email__c'}); 
sObjectFieldsMap.put('Lead', new List<String>{'LastName', 'Email'}); 
PrepareSandboxPostCopy_Batch obj = new PrepareSandboxPostCopy_Batch(sObjectFieldsMap);

  • Map<String, List<String>> sObjectFieldsMap = new Map<String, List<String>>(); sObjectFieldsMap.put('Contact', new List<String>{'Name, Email, Other_Email__c'}); sObjectFieldsMap.put('Lead', new List<String>{'LastName, Email'}); PrepareSandboxPostCopy_Batch obj = new PrepareSandboxPostCopy_Batch(sObjectFieldsMap); Id batchId = Database.executeBatch(obj); Commented Jan 11, 2019 at 5:22
  • @LokeshMalviya Please verify if your start method returns any records. I can see it uses query variable but you did not populated query string at all.

  • i didn't get you, you mean i have to also pass the query from my test class Commented Jan 11, 2019 at 6:15
  • Please put a debug to check query in start method
