Fire time based apex Salesforce

To check your time based apex class you can use the following code. My name of time based apex is: SendOppTimeBasedAlerts_Scheduler

SendOppTimeBasedAlerts_Scheduler s = new SendOppTimeBasedAlerts_Scheduler();<br data-rich-text-line-break="true" />s.execute(null);

1	SendOppTimeBasedAlerts_Scheduler s = new SendOppTimeBasedAlerts_Scheduler();<br data-rich-text-line-break="true" />s.execute(null);

Name of your apex s = new Name of your apex();
s.execute(null);

1 2	Name of your apex s = new Name of your apex(); s.execute(null);

Now open your console and go to Debug –> Open Execute Anonymous Window

Insert the code snippet that I wrote above and check the results of your Test apex.
