Hello

I have a schedulable class that implements Schedulable interface and conatins execute() method.
Now I have created Test Class but I do not manage to reach execute() method from the test class.
I have a lot of code in execute() that needs to get covered by tests.

I have seen lots of posts and official documentation, but none of the examples reach the execute method.

For example, from the official documentation :
 

@istest
class TestClass {

   static testmethod void test() {
   Test.startTest();

      Account a = new Account();
      a.Name = 'testScheduledApexFromTestMethod';
      insert a;

      // Schedule the test job

      String jobId = System.schedule('testBasicScheduledApex',
      TestScheduledApexFromTestMethod.CRON_EXP, 
         new TestScheduledApexFromTestMethod());

      // Get the information from the CronTrigger API object
      CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered, 
         NextFireTime
         FROM CronTrigger WHERE id = :jobId];

      // Verify the expressions are the same
      System.assertEquals(TestScheduledApexFromTestMethod.CRON_EXP, 
         ct.CronExpression);

      // Verify the job has not run
      System.assertEquals(0, ct.TimesTriggered);

      // Verify the next time the job will run
      System.assertEquals('2022-09-03 00:00:00', 
         String.valueOf(ct.NextFireTime));
      System.assertNotEquals('testScheduledApexFromTestMethodUpdated',
         [SELECT id, name FROM account WHERE id = :a.id].name);

   Test.stopTest();

   System.assertEquals('testScheduledApexFromTestMethodUpdated',
   [SELECT Id, Name FROM Account WHERE Id = :a.Id].Name);

   }
}

It works but it is not sufficient in my case, beacuse it only asserts that the job is in the Scheduled Jobs queue.
It actually does not trigger the execute() method.

Please how can I reach execute() ?
