Notes

All the test methods are static.

startTest():
Marks the point in your test code when your test actually begins. Use this method when you are testing governor limits.

stopTest():
Marks the point in your test code when your test ends. Use this method in conjunction with the startTest method.

@isTest
private class MyTestClass {
  @isTest
  static void myTest() {
    // Create test data
    Account acc = new Account(Name='Test Account');
    insert acc;
    
    // Mark the start of the test block
    Test.startTest();
    
    // Call asynchronous code that needs to be tested
    List<Contact> contacts = new List<Contact>();
    contacts.add(new Contact(FirstName='John', LastName='Doe', AccountId=acc.Id));
    Database.SaveResult[] results = Database.insert(contacts, false);
    
    // Verify that the asynchronous code has completed
    System.assertEquals('Success', results[0].getStatus());
    
    // Mark the end of the test block
    Test.stopTest();
  }
}

loadData(sObjectToken, resourceName):
Inserts test records from the specified static resource .csv file and for the specified sObject type, and returns a list of the inserted sObjects.

@isTest
private class MyTestClass {
  @isTest
  static void myTest() {
    // Load test data from a CSV file
    List<Account> accounts = (List<Account>) Test.loadData(Account.sObjectType, 'MyTestAccounts');
    
    // Insert the test data
    insert accounts;
    
    // Verify that the test data was inserted correctly
    List<Account> queriedAccounts = [SELECT Name FROM Account WHERE Name LIKE 'Test%'];
    System.assertEquals(accounts.size(), queriedAccounts.size());
  }
}

isRunningTest():
Returns true if the currently executing code was called by code contained in a test method, false otherwise. Use this method if you need to run different code depending on whether it was being called from a test.

public class MyUtilityClass {
  public static void doSomething() {
    if (Test.isRunningTest()) {
      // Code to execute when running in a test context
      System.debug('Running in test context');
    } else {
      // Code to execute when running outside of a test context
      System.debug('Running outside of test context');
    }
  }
}
