API / Microservices Testing using Karate tool

Steps by Steps , to Configure Karate for API testing :

1.  Create Maven project 
2.  Add Karate dependency in pom.xml file 
3.  Create Feature file and Runner.class  (in same package )

2.  Add Karate dependency :

<dependency>
    <groupId>com.intuit.karate</groupId>
    <artifactId>karate-apache</artifactId>
    <version>0.9.4</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>com.intuit.karate</groupId>
    <artifactId>karate-junit4</artifactId>
    <version>0.9.4</version>
    <scope>test</scope>
</dependency>

So complete Pom.xml file is looks like this :

<project xmlns="http://maven.apache.org/POM/4.0.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 <modelVersion>4.0.0</modelVersion>

 <groupId>com.cant</groupId>
 <artifactId>Karate.api-testing</artifactId>
 <version>0.0.1-SNAPSHOT</version>
 <packaging>jar</packaging>

 <name>Karate.api-testing</name>
 <url>http://maven.apache.org</url>

 <properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
 </properties>


 <dependencies>
  <dependency>
   <groupId>com.intuit.karate</groupId>
   <artifactId>karate-apache</artifactId>
   <version>0.9.4</version>
   <scope>test</scope>
  </dependency>
  <dependency>
   <groupId>com.intuit.karate</groupId>
   <artifactId>karate-junit4</artifactId>
   <version>0.9.4</version>
   <scope>test</scope>
  </dependency>
 </dependencies>
 <build>
  <testResources>
   <testResource>
    <directory>src/test/java</directory>
    <excludes>
     <exclude>**/*.java</exclude>
    </excludes>
   </testResource>
  </testResources>
 </build>
</project>

3.  Create Feature file and Runner.class  (in same package ) : 

3.1 Create Runner.class  :

package com..Karate.FeatureFile;
import org.junit.runner.RunWith;
import com.intuit.karate.KarateOptions;
import com.intuit.karate.junit4.Karate;

@RunWith(Karate.class)
@KarateOptions(features = "classpath:com/cop/Karate/FeatureFile/test.feature")
public class testRunner {

}

3.2 Create Feature File :

Feature: demorest api testing

 Scenario: testing a valida get endpoint 
  Given url 'https://some-api.com/api/users'
  When method GET
  Then status 200
  And assert response.length ==2
  And match response[0].name = 'FirstUser'

3.3  How to execute the Test :
--->> Just Right click on Runner.class file and run as junit test
