Hi,

     I am write a test class for batch apex,my code coverage is 33%, it is covered only start method.

How can i write test class for execute method?

Testclass for Batch Class   

@isTest

private class testtrainingbatchcls {

static testmethod void m1() {

 List<training__c> lst=new List<training__c>();

for(integer i=0;i<1500;i++) {
training__c t=new training__c();
t.name = 'T'+i;
lst.add(t);
 }

 trainingbatchcls obj=new trainingbatchcls();
Database.executeBatch(obj);

}

 }

Batch Apex Class

global class trainingbatchcls implements Database.batchable <sobject>{

global list<training__c> start(Database.BatchableContext bc){


List<training__c> lst=new List<training__c>();
for(integer i=0;i<1500;i++){


training__c t=new training__c();
t.name = 'T'+i;
lst.add(t);

}
return lst;
}



global void execute(Database.BatchableContext bc,list<training__C>lst) {

insert lst;

}

global void finish(Database.BatchableContext bc){

list<string> toaddress = new list<string>();
toaddress.add('shravankumarbagam@yahoo.com');


String subject = 'Batch class run complete';
String body = '';

Messaging.singleEmailMessage mail = new Messaging.singleEmailMessage();

mail.setToAddresses(toaddress);


mail.setSenderDisplayName('Salesforce Outbound Notification');
mail.setSubject(subject);
mail.setPlainTextBody(body);
mail.setUseSignature(false);

Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });

}

}

Hi everyone,

i have complete the test cass for my Batch apex class. when i was test that code in Developer and Test sandbox its covered 100%. when i deploy that code to QA its show only 27% without any errors.

when i check that code DEBUG LOG i got this error....

|EXCEPTION_THROWN|[EXTERNAL]|System.UnexpectedException: No more than one executeBatch can be called from within a testmethod. Please make sure the iterable returned from your start method matches the batch size, resulting in one executeBatch invocation.
12:18:21.557|FATAL_ERROR|System.UnexpectedException: No more than one executeBatch can be called from within a testmethod. Please make sure the iterable returned from your start method matches the batch size, resulting in one executeBatch invocation.

here is the Batch apex and corresponding test classes.
