Best Practices for Test Script writing

@isTest

private class Test_class {

code_block;

}

• Test methods are declared with the following syntax:

static testMethod void test_name() {

code_block;

}

• When you create a test method,
• Use static
• Use testMethod keyword
• Use void return type
• No any arguments
• No data changes performed in a test method
• Don’t send emails
• The key methods to use in your unit tests are the system.assert() methods:
• System.assert(condition)
• System.assertEquals(x,y)
• System.assertNotEquals(x,y)
• Test methods cannot be used to test Web service callouts. Web service callouts are asynchronous, while unit tests are synchronous.
• Salesforce.com recommends that you write tests for the following;
• Single action
• Bulk action
• Positive behavior
• Negative behavior
• Restricted user
•  

Best Practice for writing Test Classes

·Write fully portable tests ·        

Don’t use production data in your tests ·  

Test expected behavior first, then test unexpected behavior ·        

If you find a bug, write a test to expose it before you fix it ·        

Shoot for 100% coverage ·        

Don’t rely on Today() ·        

Put your tests on the controller and class, not in separate classes
