How can i mock auth0 authentication for testing?

Question

I am using autho0 and express-jwt in order to authenticate my app users.

Everything is really cool besides the tests. The content that i pass in my API is strictly partitioned by authors. This means you can only access a content if you own it.

I am using req.user.sub (wich is provided by jwt if the user is recognized) to set the author of the content that is being passed in my API.

Should i use req.user.name to provide the author ? If so, how can i mock the authentication in order to write my tests.

Answer 1

I implemented a simple solution which is a bit rudimentary:

public static testAuthorName = 'test-author';
private static getAuthor(req) {
    if (process.env.NODE_ENV === 'test') {
        return MyApiClass.testAuthorName;
    }
    return req.user.sub.split('|')[1];
}

This way i can just use MyApiClass.testAuthorNamestatically in my tests.
