Enonic Unit test mock

Help

According to this https://developer.enonic.com/docs/writing-unit-tests, when adding mock functions, Can we pass params to mock function?

In Java Mockito mock functions, don’t execute any statements. Instead, it’s just a “stub” or a placeholder for the real method. But it seems enonic mock function executes inside statements. Is it execute inside mock functions instead of return values?


exports.getValue = function() {
    let value = Math.random();
    console.log("value: "+ value);
    return value;
}

const valueCreator = require('/lib/valueCreator.js');
exports.get = function() {
    const value = valueCreator.getValue();
    if (value < .5) {
        return "Low";
    } else {
        return "High";
    }
}

t.mock('/lib/valueCreator.js', { 
    getValue: function () {
        return '1';
    }
});

exports.testValue = function () {
    var service = require('./myModule'); 

    var result = service.get();
    t.assertEquals('High', result);
};
