Zerocode Hello World

Sample API testing code using JUnit and Zerocode test framework

The simple and convinient way of testing your APIs

Maven and CI 🔨

Continuous Integration:

This HelloWorld project can be setup via POM as well as Gradle.

For Gradle setup, please see the README-GRADLE.md file

Maven library-

<dependency>
    <groupId>org.jsmart</groupId>
    <artifactId>zerocode-tdd</artifactId>
    <version>1.3.x</version>
</dependency>

Look maven central for latest version.

How to run the examples?

Ans: The same and usual stuff you do everyday for any maven project.

Step-1:

Import this maven project zerocode-hello-world using 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.

Sample test run log below for reference-

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"

{
    "scenarioName": "Invoke GitHub RESTful GET api and assert the response",
    "steps": [
        {
            "name": "get_user_details",
            "url": "/users/siddhagalaxy",
            "method": "GET",
            "request": {
            },
            "verify": {
                "status": 200,
                "body": {
                    "login" : "siddhagalaxy",
                    "id" : 33847730,
                    "type" : "User"
                }
            }
        }
    ]
}

github_host.properties contains-

# Web Server host and port
restful.application.endpoint.host=https://api.github.com
restful.application.endpoint.port=443

# Web Service context; Leave it blank in case you do not have a common context
restful.application.endpoint.context=

**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.

Running Local Mock Server(for other Hello World tests)

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.java

Run 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_more

Done.
