Grumpy old man here, been doing the software gig for 41 years and I’m tired. I’m NOT looking to learn eight thousand more nuanced tools and such. I want to install Postman and install the SDK (I think I need it for writing test) and use the tool. My days of enjoying the “let’s see how smart you are” circus are far behind me. Why can’t these tools just be installable without dragging people through “oh, you need this extension or you need this dependency” Jiminy Cricket!!!
Hey @rjjansky 
Welcome to the Postman Community! 
If you already have the Postman app installed or if you’re using the web version, you have all you need to start writing tests for your endpoints. 
More information around writing tests can be found here:
If you’d like more targeted assistance for your context, I’m happy to help here if you could share more details about your project
