hdel does not delete the key.

[rg185253]

hdel does not delete the key. Here is a test which shows the defect. See that the length does not change to 0, but stays at 1.

import * as redis from "redis-mock";

function checkLength(redisClient, hash) : Promise{ return new Promise((resolve, reject) => { redisClient.hlen(hash, (error, result) => { if (error) { reject(new Error(error)); } resolve(result); }); }); }

describe("hdelTest", () => {

var redisClient;
const hash = "myHash";
const key = "myKey";
const value = "myValue";

beforeEach(function () {
    redisClient = redis.createClient();
});

it("hdel should work", async (done) => {
    redisClient.hset(hash, key, value);
    let len = await checkLength(redisClient, hash);
    expect(len).toBe(1);
    redisClient.hdel(hash, key);
    len = await checkLength(redisClient, hash);
    expect(len).toBe(0);
    done();
});

});
