如何使用sinon存根oracledb?

我无法用您提供的代码复制错误,但这个快速模型可能会有所帮助:

const chai = require('chai');
const sinon = require('sinon');
const oracledb = require('oracledb');
const config = require('./dbConfig.js');

const expect = chai.expect;

sinon.stub(oracledb, 'getConnection').resolves({
  execute: function() {},
  close: function() {}
});

describe('Parent', () => {
  describe('child', () => {
    it('should work', async (done) => {
      let conn;

      try {
        conn = await oracledb.getConnection(config);

        sinon.stub(conn, 'execute').resolves({
          rows: [[2]]
        });

        let result = await conn.execute(
          'select 1 from dual'
        );

        expect(result.rows[0][0]).to.equal(2);

        done();
      } catch (err) {
        done(err);
      } finally {
        if (conn) {
          try {
            await conn.close();
          } catch (err) {
            console.error(err);
          }
        }
      }
    });
  });
});

查询通常会返回值1,但这会返回2并通过。
