Question

我正在尝试编写一种测试方法，要求我生成机会以及与机会相关的所有记录。我一直在最奇怪的地方得到空指针异常。

public static void createOpp() {
    OpportunityEscalationtest.a = new Account(Name = 'SGC Test Account'
                                            , Type = 'Customer'
                                            , Phone = '(00) 0000 0000');

    insert OpportunityEscalationtest.a;

    OpportunityEscalationtest.c = new List<Contact>();      
    Contact newC = new Contact( FirstName = 'Jack'
                                , LastName = 'O\'Neil'
                                , Phone = '(00) 0000 0000'
                                , AccountId = OpportunityEscalationtest.a.Id);

    OpportunityEscalationtest.c.add(newC);

    newC = new Contact( FirstName = 'Samantha'
                        , LastName = 'Carter'
                        , Phone = '(00) 0000 0000'
                        , AccountId = OpportunityEscalationtest.a.Id);

    OpportunityEscalationtest.c.add(newC);

    newC = new Contact( FirstName = 'Daniel'
                        , LastName = 'Jackson'
                        , Phone = '(00) 0000 0000'
                        , AccountId = OpportunityEscalationtest.a.Id);

    OpportunityEscalationtest.c.add(newC);

    insert OpportunityEscalationtest.c;

    Contact priCont = [Select Id from Contact where FirstName = 'Jack' limit 1];
    OpportunityEscalationtest.a.GillForce__Primary_Contact__c = priCont.Id;

    OpportunityEscalationtest.o = new Opportunity( Name = 'Mountain Complex Water'
                                                 , CloseDate = system.today()
                                                 , StageName = 'Business Analysis'
                                                 , AccountId = OpportunityEscalationtest.a.Id);

    insert OpportunityEscalationtest.o;

    for (Contact cont : c) {
        OpportunityContactRole role = new OpportunityContactRole( ContactId = cont.Id
                                                                , OpportunityId = OpportunityEscalationtest.o.Id
                                                                , Role = 'Descision Maker');

        role.IsPrimary = (OpportunityEscalationtest.a.GillForce__Primary_Contact__c == cont.Id);

        insert role;
    }
}

在这两行代码之间抛出错误：

    insert OpportunityEscalationtest.c;

    Contact priCont = [Select Id from Contact where FirstName = 'Jack' limit 1];

我有点难过，除非我弄错了这段代码应该是自包含的。任何想法都会很棒。

Answer 1

首先，我会尝试将您的测试类的API版本设置为22.0（类体的版本Sttings选项卡）并尝试再次测试。

Answer 2

你在线上遇到错误

Contact priCont = [Select Id from Contact where FirstName = 'Jack' limit 1];

接缝失败的接缝（可能是由于触发器中的某些条件）。或者它可能只是没有插入一个名字杰克的特定联系人（也许是因为姓氏）。

如果我是你，我该怎么办？我将检索所有联系人并将其打印到调试（或者对您来说更容易）。在此之后，您将了解问题所在。
