ApexGuru Test Case Antipattern: Using the testMethod Keyword

Scope

Detection and recommendation

Detection Example

public class MyTestClass {
   static testMethod void myTest() {
      System.debug('This test will be versioned out soon as it has testMethod keyword');
   }
}

Recommendation

Always annotate test classes with @isTest. Avoid legacy syntax. Adopt modern standards that properly recognize and execute all test methods.

@isTest
private class MyTestClass {
   @isTest
   static void myTest() {
      System.debug('This test follows Salesforce recommended practices');
   }
}
