const e2eTestsSuite = {
  [`[TEST] Sensor E2E Tests`]: {
    tests: {
      "Publish test X": {
        tests: [
          {
            skip: false,
            name: "Can publish",
            options: () => {},
            url: () => `mqtt://${mqttUrl}`,
            verb: "publish",
            packet: () => ({
              topic: "testTopic",
              payload: "testPayload",
            }),
            timeout: 150,
            expect: async (packet) => {
              expect(packet.payload).to.be.equal(testPayload);
            },
            error: (err) => {
              throw err;
            },
          },
        ],
      },
      "Publish / subscribe test X": {
        tests: [
          {
            name: "Can subscribe and receive message",
            options: () => {},
            url: () => `mqtt://${mqttUrl}`,
            error: (err) => {
              throw err;
            },
            steps: [

                packet: () => ({
                  topic: `12345-in/1/#`,
                }),
                timeout: 200,

                  expect(message.payload).to.be.equal("42");
                },
              },
              () => ({
                verb: "publish",
                packet: () => ({
                  topic: "12345-in/1/3303/0/1/5700",
                  payload: "42",
                }),
                timeout: 300,
