Understanding REST

Great introduction article - https://www.smashingmagazine.com/2018/01/understanding-using-rest-api/

API testing is done with the following tools:

Postman for exploratory testing

Karate for automation

The following are public APIs that you can use to try out API testing tools.

IDE Setup

    The project expects JDK 1.8 (at least jdk1.8.0_162), Maven 3.5.2 and JUnit 4.

    Install the following:

    Java Development Kit: JDK 8 (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)

    Apache Maven 3.5 or newer - binary zip archive (https://maven.apache.org/download.cgi)

    IDE: Eclipse IDE for Java EE Developers Oxygen or newer. NOTE: You need the Java EE Developers edition (http://www.eclipse.org/downloads/packages/)

Set JAVA and Maven environment variables: Under System variables,

    Define JAVA_HOME with the path to the JDK installation.

    For example:

    JAVA_HOME

    C:\Program Files\Java\jdk1.8.0_192

Add the following variables under Path:

    %JAVA_HOME%\bin

    <path to Maven folder>\bin

    For example: 'C:\apache-maven-3.5.2\bin'

In Eclipse, set up your workspace as follows:

    Set Maven path: Go to Window menu > Preferences > Maven > Installations, add Maven install location and set as default.

    Set JDK path: Go to Window menu > Preferences > Java > Installed JREs, add installed JDK (as Standard VM) and set as default.

    Set default Java path to the JDK: Go to Window menu > Preferences > Java > Installed JREs > Execution Environments, set 'JavaSE 1.8' to the JDK.

    JUnit comes pre-installed with Eclipse. No further configuration needed for this.

    Install the free Cucumber-Eclipse plugin. Go to Eclipse Help > Eclipse Marketplace and install the latest version. This will provide syntax-coloring for feature files.

Go to the Eclipse Preferences > Cucumber > User Settings, and enter the following Root Package Name: com.intuit.karate . This resolve an issue where you encounter "does not have a matching glue code" warnings (refer to the Cucumber-Eclipse wiki for more).

Your environment is set. Follow the Bitbucket repo readme instructions to clone and set up the project.
