Course Overview
Alright, so you want to get into API testing, right? Smart move. APIs are the backbone of pretty much everything today, and if you can test them effectively, you're golden. Here at COSS, we're not just going to show you buttons; we're going to teach you *how* to think like an API tester using Postman. Over the next 2 months, you'll dive deep into Postman 10.x, learning everything from basic GET requests to complex data-driven tests. We'll cover authorization, scripting with JavaScript for pre-request and test scripts, and even integrate your Postman collections with Newman for CI/CD. Why just click when you can automate? This isn't theory-heavy. You'll work through 10+ hands-on labs and finish 6 real-world projects that mirror what you'd do at companies like TCS or Wipro in Gachibowli. By the end, you'll be confident in your ability to validate any REST API. You're looking at an average starting salary range of 4-7 LPA in Hyderabad for an API Testing role.
