当前对包含 this.refs [ data ] 的函数进行单元测试。由于我只能进行浅层渲染，所以我一直不确定。我试图通过这样做来嘲笑诗意

var refs = { '001m000000RkzHuAAJ': function () {} };
var refStub = sinon.mock(refs);

但我相信因为该函数正在执行 this.refs 而不是 refs 它不起作用。关于如何模拟 this.refs 的任何想法？

编辑：

        const wrapper = shallow (
            <CashAllocation receipt={receipt} slds={''} clients={clients} billingStatements={billingStatementswithAllocation} userTitle={'Premium Accounting User'} userPermission={2} />
        );
        wrapper.instance().autoApply();
        wrapper.update();

        console.log(wrapper.state('billingStatements'));

它在叫什么：

autoApply() {
    const clientsSortedbyLargestOutstanding = this.props.clients.slice().sort(function(a,b) {
        if (a.outstandingBalance < b.outstandingBalance) {
            return 1;
        } else if (a.outstandingBalance == b.outstandingBalance) {
            return 0;
        } else {
            return -1;
        }
    });
    var amountToApply = this.state.receipt.Amount_Remaining__c;
    clientsSortedbyLargestOutstanding.forEach(function(client) {
        var amountApplied = 0;
        if (this.state.receipt.Amount_Remaining__c == 0) {
            amountToApply = 0;
        } else {
            if (client.outstandingBalance < (amountToApply + client.currentAllocation)) {
                amountApplied = client.currentAllocation + (client.outstandingBalance - client.currentAllocation);
                amountToApply = amountToApply - (client.outstandingBalance - client.currentAllocation);
            } else {
                amountApplied = client.currentAllocation + amountToApply;
                amountToApply = 0;
            }
        }

        this.refs[ client.Id ].autoApply(amountApplied);
    }, this);
}

我收到以下错误。当我挖掘堆栈跟踪时，它的 this.refs 导致它：

TypeError: Cannot read property 'autoApply' of undefined
