Will Detox tool scan QR codes

Question

Can someone help me and tell me whether Detox test tool supports QR code scanning for mobile apps (Android & iOS)? I have seen in the Github page that there was some sort of bug raised and the question has been moved to stackoverflow and I couldn't find it here.

Answer 1

I don't know how your application would scan QR codes but here is how you can do to test it.

ScanQR.jsx

function ScanQR() {
  const [data, setData] = useState(null);

  function scan() {
    // here is the logic to scan
    setData(data);
  }
  ...
}

Then you will create a mock file ScanQR.2e2.jsx following this instructions

ScanQR.2e2.jsx

function ScanQR() {
  const [data, setData] = useState(null);

  function scan() {
    // replace the logic to scan with actual data results
    const data = 'some data here';
    setData(data);
  }
  ...
}

This way whenever you test you app the mock file will replace the actual file in which you really scan QR codes using camera.
