FlowProcess

Manage the execution and interfacing of runtime resolved Flows in Apex

The FlowProcess class wraps the Apex Flow API and allows you to manage the execution and interfacing of runtime resolved flows in Apex. It focuses on providing support for declaring inputs and outputs as well as integrating with Custom Metadata types as a means to allow admins to control which flows are invoked

List<Account> accounts = (List<Account>)
    new FlowProcess().
        named(dynamicFlowName).
        with('SomeRecords', [select Name, Id from Account]).
        returning('FilteredAccounts'));

You can also reference a Custom Metadata Type to allow Admins to configure the Flow to run

List<Account> accounts = (List<Account>)
    new FlowProcess().
        named('FilterAccounts',
           MyAppFlows__mdt.SObjectType,
           MyAppFlows__mdt.FlowName__c).
        with('SomeRecords', [select Name, Id from Account]).
        returning('FilteredAccounts'));

You can also mock Flow invocations during tests.

// Given 
FlowProcessRunner mockRunner = 
    (FlowProcessRunner) Test.createStub(FlowProcessRunner.class, new RunnerMock());          
FlowProcess.setMock(mockRunner);
        
// When
List<Account> accounts = (List<Account>) 
    new FlowProcess().named('GetSomeRecords').returning('Records');
            
// Then
System.assertEquals(1, accounts.size());
System.assertEquals('MyAccount', accounts[0].Name);
