Frequently Asked Questions

Answers to what is API testing, eligibility, and placement.

• What is API testing and why is it important?Answer

  **API testing** involves verifying APIs (Application Programming Interfaces) directly—checking their functionality, reliability, performance, and security. Unlike UI testing, **api testing means** validating the logic layer. It’s crucial because it catches bugs early (Shift-Left) and ensures different software systems communicate correctly.
• How is this different from a manual testing course?Answer

  While we cover **manual API testing** using Postman, this course focuses heavily on **API automation** and technical validation (JSON/XML). It is an advanced module often taken after or alongside a **manual testing course with placement**.
• Do you cover API automation testing tools?Answer

  Yes, we extensively cover **Postman** (for both manual and automated testing) and **Newman** for CLI execution. We also introduce concepts relevant to **Rest Assured** and other **API automation testing tools**.
• Can I learn API testing without coding?Answer

  Yes! Tools like **Postman** allow you to perform extensive testing with minimal coding. We teach you the necessary JavaScript snippets for validation, making it easy to **learn API testing** even if you are a beginner.
• What are some API testing examples I will practice?Answer

  You will work on **REST API examples** like a Contact List app and an Employee Management system. You will verify **test api post request**, GET, PUT, DELETE methods, and Authorization headers using real **public api for testing**.
• Do you provide placement support?Answer

  Absolutely. As a leading **software testing training** institute in Mumbai, we provide placement support, including resume building (highlighting your **API test cases examples**), mock interviews, and referrals.
• How do I test API endpoints in this course?Answer

  We use a hands-on approach. You will learn **how to test api** endpoints by sending requests, analyzing response codes (200 OK, 404 Not Found), validating JSON bodies, and checking response times.
• Is this course strictly for Mumbai residents?Answer

  No, while our offline campus is in Thane/Mumbai, our **online API testing** classes are available globally. You get the same **manual testing course with placement** benefits and mentor support online.
