API Automation Tutorial

In this tutorial you are going to learn How to Automate the REST API's in Java using RESTAssured Library

The tech stack used for this tutorial are:

1. JAVA as the programming language for writing test code
2. TestNg as the framework
3. Gradle as the build tool
4. IntelliJ as the preferred IDE for writing java code.

Getting Started

Setup your machine.

1. Install JDK 1.8
2. Install IntelliJ (Community edition is fine)
3. Install Gradle

Cloning & Importing the Project

1. Clone the project from git clone https://github.com/vinaykumarvvs/api-automation-tutorial.git
2. Import the project (api-automation-tutorial) in IntelliJ File -> New -> Project from Existing Sources -> Browse Project Location -> build.gradle
3. Now click on auto import -> Ok wait until the IntelliJ downloads all the dependencies

Running tests

Note: For 2nd & 3rd steps, you need to follow this way OpenTerminal/CMD -> cd <change-to-project-location>

1. You can run the tests directly from the IntelliJ, by right-clicking and Run test.
2. For Linux/Mac users: gradle clean build runTests or gradle clean build test
3. For Windows users: gradlew clean build runTests or gradlew clean build test
