How to write test case for if condition

[Jenifer Rajakumar]

Hi

Iam very new to junit, iam trying junit at first time so please guide to this will be foundation for me to get concepts about junit.

My code was

public List<InitiateSearchEntity> getInitiateSearchEntities(MasterSearchCriteria searchCriteria) throws ApplicationException {		
		
		List<InitiateSearchEntity> initiateSearchEntities = new ArrayList<InitiateSearchEntity>(0);
		final InitiateMasterSearchCriteria initiateCriteria = masterSearchTransformer.preProcess(searchCriteria, getInitiateHelper());
		
		// fetching the entRecNos based SERCHTYPE			
		if(searchCriteria.getSearhType().equals("MemGet"))
		{
			initiateSearchEntities = this.getInitiateSearchEntitiesMemGet(initiateCriteria,searchCriteria);
		}
		if(searchCriteria.getSearhType().equals("MemSearch"))
		{
			initiateSearchEntities = this.getInitiateSearchEntitiesMemSearch(initiateCriteria, searchCriteria);
		}
		
		return initiateSearchEntities;
	}

This code is having link to private method but simple 2 are 3 steps i want to get idea clear.so help me. I tried some little code in that iam getting error so please help me and guide me.

my junit code

	}
	@Test void testGetInitiateSearchEntities(){
		List<InitiateSearchEntity> initiateSearchEntities = new ArrayList<InitiateSearchEntity>(0);
		initiateSearchEntities.add(null);
		
		
		Assert.assertNotNull(mstrSearchDAOImpl.getInitiateSearchEntities(searchCriteria));
	}

my error is

That is relatively straightforward - you will find it an easy fix. I'm going to point you to the documentation since it explains it better than I can:

You might want to look at Oracle's Controlling Access to Members of a Class tutorial. Or possibly a better bet (since the first link is a bit terse), the Oracle lesson on Object-Oriented Programming -> Data Access Levels might point you to the easy fix.

Just to add to what Andrew he pointed you...

Exception trace has given you a message; Method testGetInitiateSearchEntities should be public , and I believe it is detailed enough.

Also if you look at the getInitiateSearchEntities() and testGetInitiateSearchEntities() methods, first one has public, but not the second one. So always make a practice to read the exception content and see whether you can grab something on how to resolve it.
