Why is TestCafe crashing on launch testing Electron app with simple command-line? - testing

Question

I am attempting to run a test on our Electron app using TestCafe. I am getting an error mentioning a "-m" command, however that is not used in my script or command line.
I have everything set up as described here:
https://github.com/DevExpress/testcafe-browser-provider-electron#testing-an-executable-electron-application
C:\packages>testcafe -d "electron:C:\Program Files\OurApp\"
"C:\Temp\test.js" -hostname localhost
Using locally installed version
of TestCafe. ERROR Tested app failed with an error:
Error: Command failed: -m '-m' is not recognized as an internal or
external command, operable program or batch file.

Type "testcafe -h" for help.
The script for test.js is below:
import { Selector } from 'testcafe';
fixture `Electron test`
.page('./index.html');
test('smoke 1', async t => {
await t
.debug()
.click(Selector().withText('Create a new configuration'));
});
What could be the cause?

Answer 1

The cause is in an incorrect -hostname argument. It should be --hostname. I'm not sure why some -m error appears but tests work after I fix incorrect argument syntax.
