Hi,
I am non technical newbie trying to make a hotel system saas.
I hired a developer to make the saas and he is working in laravel framework, my question is how can I test the product and make sure there are no bugs after he finish the development?
And can a non technical build a saas by hiring freelances ?
You can record selenium scripts and run without any code. You can build a saas without technical background but it is harder than the other.
Go through the whole workflow to make sure it works as expected. Or hire a freelance tester. Keep in mind there is no bug-free code in the universe.
I would consider hiring a third party not only to test the work but confirm that the project/product is secure and meets the requirements you set.
If you have money, there is no reason why you can't pay someone to build a product. It is not easy, and things can often go wrong. Finding good reliable people is often the hardest bit.
With regards to testing - nothing will ever be bug free. Generally you should want to test on a base set of browsers / mobiles. You could probably do a chunk of it yourself, going through all the user flows you can think of, seeing if it works as you would expect.
The other option would be to hire a freelance software tester to help you out.
