Apex-可调度的类无法执行可批量的类

Question

我在编写的Batchable和Schedulable Apex类方面遇到了麻烦。基本上，Schedulable类不会调用Batchable类在其中运行代码。这是我写的：

rw_BillingInvoiceCreationSchedulable.apxc

global class rw_BillingInvoiceCreationSchedulable implements Schedulable {
    global void execute(SchedulableContext sc) {
        System.debug('Batchable queued for execution');
        rw_BillingInvoiceCreationBatchable b = new rw_BillingInvoiceCreationBatchable();
        Id batchId = Database.executeBatch(b);
        System.debug('Batchable was executed: ' + JSON.serialize(b));
    }
}

rw_BillingInvoiceCreationBatchable.apxc

global class rw_BillingInvoiceCreationBatchable implements Database.batchable<SObject> {

    global Database.QueryLocator start(Database.BatchableContext BC) {
        System.debug('Batch Apex called');
        Date closingTime = date.today().toStartOfWeek();
        return Database.getQueryLocator([SELECT Id, Name, rw_Batch_Sequence__c, rw_End_Date__c, rw_Closed__c, rw_Customer__c, rw_Start_Date__c, rw_Warehouse__c
                                        FROM rw_Invoice_Batch__c
                                        WHERE rw_Closed__c = FALSE]);
        // AND rw_End_Date__c < :closingTime
    }

    global void execute(Database.BatchableContext info, List<rw_Invoice_Batch__c> scope) {
        System.debug('Invoices about to be updated');
        List<rw_Invoice_Batch__c> invoices = new List<rw_Invoice_Batch__c>();
        List<Account> activeCustomers = [SELECT Id, Name
                                         FROM Account
                                         WHERE Inventory_Management__c = TRUE OR Order_Management__c = TRUE];
        for(rw_Invoice_Batch__c i : scope) {
            i.rw_Closed__c = TRUE;
            invoices.add(i);
            rw_InvoiceGenerator.generateInvoice(i);
        }
        update invoices;
        System.debug('Invoices updated to closed');
    }

    global void finish(Database.BatchableContext BC) {

    }
}

就测试类而言，我可以确认Batchable类正在运行。我运行了它的测试类，它总是返回成功，但是对于Schedulable类，测试类或实际运行它总是会得到相同的结果：什么都没有。我不确定是否有任何限制或调整可以允许代码运行，但我对它的含义持开放态度。
