Please help me to write test class for event object. I am getting only 25% code coverage.

// Method to validate start and End Time on events
    public static void ValidateStartEndTime(List<Event> evts) {
        for(Event ev: evts)
            if(ev.StartDateTime.time() < Time.newInstance(7, 30, 0, 0))
                ev.StartDateTime.addError('Start time should be greater than or equals to 7:30 AM');
            if(ev.EndDateTime.time() > Time.newInstance(18, 00, 0, 0))
                ev.EndDateTime.addError('End time should be less than or equals to 6 PM');

Test class:

public class EventTrigger_Test {

    static testMethod void myUnitTest1(){

        Event e = new Event();

            insert e;

In the test method you have two problems:

1- The AddError will stop from going forward in the code, so if you get into the first if-statement you won't get into the second. That's why you need two seprate test methods.

2- The logic in the trigger check only the time and not the date, so it doesn't matter in which day you are, as long the time is good (between 7:30 and 6). That means you will have to change the time in the test method.

You can check this LINK to see how to set the datetime (also the time)

  • Can you show me syntax to cover date time with sample test class.

    e.StartDateTime = Datetime.newInstance(2019, 1, 1, 03, 00, 00); --> This is (03:00 am)

  • It's not covering.Can you please write the test code syntax for class

    try to print out some System.debug to check the values in every stage and why it's not getting in the if-statements

  • @Sohel for e.StartDateTime and e.StopDateTime please enter a new instance of time as Mo Hamanda showed. Otherwise the test will sometimes pass and sometimes fail depending on the time of day it is.
