How to add custom success message in Mocha tests? - mocha.js

Question

I have a loop inside a test case where I repeat a part of the test for each data sample.
How can I add a custom sucess message indicating that specific data, representing a test case, was sucessful?
For instance, my code is like:
it('Should not allow saving bad data: ', async function () {
let badData = TestDataProvider.allData.invalid;
for (let i = 0; i < badData.length; i++) {
let d = badData[i];
let res = await request.post('/data').send(d);
let object = null;
try {
object = JSON.parse(res.text);
} catch (e) {
object = {};
}
expect(res.statusCode).to.equal(206);
expect(object).not.to.contain.a.property('_id');
console.log('Verified case: ' + d.testDesc);
}
});
I want the "Verified case..." message to appear as successful test runs and not console messages in reports.
The testDesc attribute holds test description like: "Missing field a", "Invalid property b", "Missing field c".

I solved the problem creating dynamic tests:
const allData = JSON.parse(fs.readFileSync('data.json'), 'utf8'));
allData.invalid.forEach((badData) => {
it('Should not allow saving with: ' + badData.testDesc, async () => {
let res = await request.post('/data').send(badData);
let d = null;
try {
d = JSON.parse(res.text);
} catch (e) {
d = {};
}
expect(res.statusCode).to.equal(206);
expect(d).not.to.contain.a.property('_id');
});
});
