Debug with Assert class

How to debug code with the Assert class?

There are numerous Apex debugging methods.

However, debugging with the Assert class is a straightforward and efficient way to debug both Apex and Apex Unit Tests.

@IsTest
static void myTestMethod() {
    Account acc = [SELECT Id, Name FROM Account WHERE Name = 'TestAcc'];

    Assert.areEqual(new Account(), acc); // This will fail, and you will see the value

    List<Contact> contacts = MyController.getAccountContacts(acc.Id);
    ...
}

System.AssertException: Assertion Failed:
Expected: Account:{},
Actual: Account:{Id=0013M00001HrGndQAF, Name=Beyond The Cloud}

Why can it be useful?

Debug Unit Test - You can view System.debug statements in Apex, but not in Apex Unit Tests. Adding an Assert statement allows you to inspect the variable values. Debug in CICD - Encounter issues in your CI/CD process? Tests work in the development environment but fail during deployment? Adding an Assert statement can help you debug these issues.
