We use Postman for API testing, and I am also using it for training purposes.
I have found that our time is significantly saved in terms of debugging and writing down the code manually as Postman allows us to add the code with the help of test and assertions, eliminating the need to write code ourselves.
The user interface is very easy to learn and use, and it is a lightweight application. It's also an open-source tool for API testing. One of the best features is that you really don't need to be an expert in any programming language because Postman can generate the codes automatically for you.
Postman needs to improve its support for a lot of integrations. Additionally, browser add-ins or extensions would be helpful.
I have been using Postman for quite a while, perhaps for the past seven or eight years.
The initial setup is very easy and simple.
Being an open-source tool, it's a lightweight tool that I would prioritize as number one.
I would prefer Postman as my priority since it's an open-source tool, simple to install and use. You don't need to be a programming expert to use it, which presents several advantages.
I'd rate the solution nine out of ten.
