 How to check the ignition coil for a spark?

The engine dashboard light is on on my car. The engine vibrates and has a lack of power.

The diagnostic tool show the trouble code P0304.

It means that there are misfire on the cylinder number 4.

After having tested the charging circuit, I test the ignition coil on the defective cylinder with an ignition coil tester.

I show you how this tool works.

Since the ignition works well, I test the spark plug with a spark plug tester. The spark plug doesn't work.

So I replace it and check that the engine works well.

The dashboard light becomes off and there isn't trouble code anymore.
