how do i write test class for batch apex scheduler?

hi all

 

in the batch apex sheduler,i did n't provide system.scheduler like data and time,i have mentioned as manually such as follows,

 

batchapexscheduler:

----------------------------

sambatchapexscheduler  testbas=new sambatchapexscheduler();

database.executebatch(testbas,200);

 

so how do i write test class for above and please let me know asap

Thanks!

This is covered in detail in the Apex Developer's Guide - section Apex Scheduler

 

When you are testing the call to System.schedule, the actual Cron exp[ression you use can be almost anything as the test wraps the call to System.schedule with a test.startTest(), Test.stoptest(). 

 

In a test context, the schedulable class will execute as soon as Test.stopTest() is encountered, regardless of the actual CRON expression. Note in the example that a date far in the future is used in the test method.

 

In my code, I have  1+ separate test methods for the class that implements Schedulable -- they test the class assuming it has been scheduled.  Then, just like in the Apex doc example, I have a separate testmethod to verify that the class gets scheduled and some trivial test to prove that the scheduled class runs.  This way, you can keep your test code compartmentalized

 

..many methods to test the business logic of your schedulable class

.. 1 method to verify that you can schedule

I think I'm confused about your scenario --  do you have a batchable APEX class that you want to run as a scheduled job? If so, you're going to need more than 2 lines of code.  Please review the SFDC Apex doc on batchable classes as well as schedulable classes - these are two different concepts.  Each can be tested independent of each other.

 

To make the problem simpler for yourself, work on the schedulable class first that simply executes a dummy method on a dummy class.  Then develop the test code for the batchable class without worryng how to schedule it. Finally, replace your call to the dummy method with an object instantiation of the batchable class followed by Database.executeBatch(my BatchableObject);

Yes eric, it is batch apex and when i was trying to write test class getting error as 'External entry point' Test.StartTest(); sambatchapexscheduler testbas=new sambatchapexscheduler(); string sche='0 0 13 **?'; system.schedule('test'sche,testbas); test.stopTest(); Please let me know the solution asap. Thanks!
