Sample API testing code using JUnit and Zerocode test framework
The simple and convinient way of testing your APIs
Continuous Integration: 
For Gradle setup, please see the README-GRADLE.md file
<dependency>
<groupId>org.jsmart</groupId>
<artifactId>zerocode-tdd</artifactId>
<version>1.3.x</version>
</dependency>- Look maven central for latest version.
Ans: The same and usual stuff you do everyday for any maven project.
Step-1:
- Import this maven project
zerocode-hello-worldusing Eclipse or IntelliJ or your favourite IDE
* i.e. /zerocode-hello-world/pom.xml,
* mvn clean install -DskipTests
* The above command brings all the libs to the local .m2 repo
Step-2:
- Run the JustHelloWorldTest.java test (it invokes GitHub REST https apis and asserts the result)
* i.e. src/test/java/org/jsmart/zerocode/testhelp/tests/helloworld/JustHelloWorldTest.java
* Then, you can fiddle with the assertions/verify section and run the test again,
observe the PASS/FAILURES at the console.
* To run more tests go to individual package and run. e.g. folders- helloworldgithub, helloworldmore etc
Done. That's it. It is as simple as that.
See more(optional) below what happens when test run is completed.
Quick look at the test case and its run log below-
- JUnit Test case-
@TargetEnv("github_host.properties")
@RunWith(ZeroCodeUnitRunner.class)
public class JustHelloWorldTest {
@Test
@Scenario("helloworld/hello_world_status_ok_assertions.json")
public void testGet() throws Exception {
}
}- Test case JSON content of "helloworld/hello_world_status_ok_assertions.json"

**FINISHED executing all Steps for [Invoke GitHub RESTful GET api and assert the response] **.
Steps were:[get_user_details]So what happens when your tests grows to thousands in numbers? You then, need to organize them by feature, by consumer and/or by profile etc. Hence Zerocode helps here to maintain peace!
Also it saves you from creating hundreds of java Pojos with getters/setters, creating their builders and getting lost in visualizing or interpreting in mind how the actual request/response could look like.
This hassle one has to face everytime you run the tests or encounter a test failure or during a bug/scenario analysis.
Step-3: (Optional Step to bring up local REST server and fiddle with the tests)
Start the Local Mock REST server
* i.e. just Run as main() -> test/.../RunMeFirstLocalMockRESTServer.java.
* Then you can run the src/test/java/org/jsmart/zerocode/testhelp/tests/helloworldmore/JustHelloWorldMoreTest.javaRun as Suite:
* src/test/java/org/jsmart/zerocode/testhelp/tests/HelloWorldGitHubSuite.java
More examples:
* src/test/java/org/jsmart/zerocode/testhelp/tests/helloworldmore/JustHelloWorldMoreTest.java
* -or- Browse under test/resources/ folders- helloworld, helloworld_github_REST_api, helloworld_moreDone.
