Karma test runner does not run mocha tests - node.js

Question

When running tests using mocha (./node_modules/.bin/mocha test) the tests in the test file run, and the following is outputted to powershell:
TEST ************
myFunc
- a pending test
0 passing (4ms)
1 pending
When running the same file using karma (./node_modules/.bin/karma start), the console.log("TEST ************"); prints out, but the test suite does not run. Karma gives the following output:
10 05 2020 14:27:24.326:WARN [karma]: No captured browser, open http://localhost:9876/

test.js
console.log("TEST ************");
describe('myFunc', function() {
it("a pending test");
});
karma.conf.js
module.exports = function(config) {
config.set({
frameworks: ["mocha"],
files: [ "test/test.js"],
plugins: [
"karma-chrome-launcher",
"karma-mocha"
],
browsers: ["ChromeHeadless"]
})
}
package.json
{
"name": "karma-mocha-test",
"devDependencies": {
"karma-chrome-launcher": "^3.1.0",
"karma": "^5.0.5",
"karma-mocha": "^2.0.1",
"mocha": "^7.1.2"
}
}
What am I missing here to make karma run mocha tests and display the results in powershell?

Answer 1

I'm missing a reporter, like so:
,reporters: ["mocha", "coverage-istanbul"]
