Test Class code coverage ( only couple of lines )

Question

Hello this is the first time i try to write a test class, but i don't understand exactly how i can test if the flow was actually launched. Can someone help me with the test class ? It's only a couple of lines

global class ScheduledContractSend Implements Schedulable {
global void execute(SchedulableContext sc)
    {
        Map<String, Object> Params = new Map<String, Object>();
        Params.put('recordId','006p000000Aal2EAAR');
        Flow.Interview.testcontract flow1 = new 
        Flow.Interview.testcontract(Params);         
        flow1.start();}}

Test Class :

@isTestprivate class TestScheduledContractSend {
static testMethod void validateScheduledContractSend() {
    }}

Answer 1

This test class worked for me.

private class ScheduledContractSendTest{
    @isTest
    private static void executeTest(){
        Test.startTest();
        ScheduledContractSend obj = new ScheduledContractSend();
        obj.execute(null);
        Test.stopTest();
    }
}
