Rule: ApexUnitTestClassShouldHaveAsserts

Message

Apex unit tests should System.assert() or assertEquals() or assertNotEquals()

Description

Apex unit tests should include at least one assertion. This makes the tests more robust, and using assert with messages provide the developer a clearer idea of what the test does. Custom assert method invocation patterns can be specified using the 'additionalAssertMethodPattern' property if required.

Example

@isTest
public class Foo {
    public static testMethod void testSomething() {
        Account a = null;
        // This is better than having a NullPointerException
        // System.assertNotEquals(a, null, 'account not found');
        a.toString();
    }
}
