如何使用JEST测试是否将正确的参数传递给APEX类

问题描述

我是Salesforce中开玩笑的测试新手。我正在尝试测试是否在单击按钮时将正确的参数传递给了APEX方法，但是出现了错误提示

    TypeError: Cannot set property 'id' of null

      298 |     // Select button for executing Apex call
      299 |     const buttonEl = element.shadowRoot.querySelector('lightning-button[class="reapply-button slds-m-left_x-small"]');
    > 300 |     buttonEl.id = USER_INPUT;
          |     ^
      301 |     buttonEl.click();

这是我在HTML中的for：each按钮

<lightning-button class="reapply-button slds-m-left_x-small" variant="brand-outline" label="Reapply" onclick={handlereapply} id={current.Id}></lightning-button>

这是我开玩笑的测试课

import getSubcontractWithRecordId from "@salesforce/apex/subcontractApp.getSubcontractWithRecordId";
// Mocking imperative Apex method call
jest.mock(
  "@salesforce/apex/subcontractApp.getSubcontractWithRecordId",() => {
    return {
      default: jest.fn()
    };
  },{ virtual: true }
);
const APEX_RECORD_BY_ID = [
  {
    Id: "a1B3I100001JBkrUAG",Start_Date__c: "2020-09-18",End_Date__c: "2020-10-10"
}];
describe("c-subcontract-app-apex-imperative-call-method",() => {
  afterEach(() => {
    while (document.body.firstChild) {
      document.body.removeChild(document.body.firstChild);
    }
    jest.clearAllMocks();
  });

  function flushPromises() {
    // eslint-disable-next-line no-undef
    return new Promise((resolve) => setImmediate(resolve));
  }

 it('passes the record id input to the Apex method correctly',() => {
    const USER_INPUT = 'a1B3I100001JBkrUAG';
    const APEX_PARAMETERS = { record_id: USER_INPUT };

    getSubcontractWithRecordId.mockResolvedValue(APEX_RECORD_BY_ID);

    // Create initial element
    const element = createElement('c-apex-imperative-method-with-params',{
        is: SubcontractApp
    });
    document.body.appendChild(element);

    // Select button for executing Apex call
    const buttonEl = element.shadowRoot.querySelector('lightning-button[class="reapply-button slds-m-left_x-small"]');
    buttonEl.id = USER_INPUT;
    buttonEl.click();

    return flushPromises().then(() => {
        // Validate parameters of mocked Apex call
        expect(getSubcontractWithRecordId.mock.calls[0][0]).toEqual(APEX_PARAMETERS);
    });
});

});

这是顶点类声明

  public static Subcontract__c getSubcontractWithRecordId(String record_id){
