入站邮件处理程序的 APEX 测试 Class

Question

I am pretty green in APEX, but was tasked to write a class and subsequent test class for a daily inbound email to load to an object with raw call log data.

我的测试覆盖率为 52%，它失败的主要区域是我加载的图片中的区域

任何帮助，将不胜感激！！

Class：

global class Five9ReportingAutomation implements Messaging.InboundEmailHandler {
    
global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email, Messaging.InboundEnvelope envelope) {
        Messaging.InboundEmailResult result = new Messaging.InboundEmailresult();
        Messaging.InboundEmail.BinaryAttachment[] tAttachments = email.binaryAttachments; // // Since Attachment is CSV we are taking as BinaryAttachments. 
        list<Five9_Call_Data__c> lstFive9_Call_Data = new list<Five9_Call_Data__c>(); // list of Five9.
        String csvbody='';
        
        list<list<String>> allFields = new list<list<String>>(); // list of rows in csv
        list<String> lines = new list<String>(); // Rows of CSV
        list<String> headers = new list<String>(); // Field names
