test api implementation code example

Example 1: what do you test in response api

Basicall we are checking response body
to verify if request matches with response.
In the response we are verifying
(body, status code, header, response time,
 test structure of json against the given jsonSchema)
 
 
If file not under resources: 
File schemaFile = new File("src/test/resources/postSuccessResponseSchema.json");

     given()
        .spec(adminReqSpec)
        .contentType(ContentType.JSON)
        .body(abcUtil.getRandomHeroPOJO_Payload()).
     when()
        .post("/HEROS").
     then()
        .body(matchesJsonSchema( schemaFile )  ) 
        
        
If schema file under resources:
  given()
      .spec(adminReqSpec)
      .queryParam("nameContains","a")
      .queryParam("gender","Female").
  when()
      .get("/abc/search").
 then()
 	  .time( lessThan(2000L));	
      .body(matchesJsonSchemaInClasspath("searchSpartanSchema.json") )

Example 2: api testing approach

Write suitable test cases for the APIs
and use testing techniques 
like exploratory testing,
boundary value analysis, positive and negative 
testing for understanding the functionality.

• Verify the calls with combination of
two or more value added parameters.
• Define the scope and basic
functionality of the API program.
• Define the accurate input parameters.
• Test case execution and comparison 
of the results with expected results.
• Determining API behavior under
conditions like the connection with files,
etc.

- There are different types of 
output observed of an API also:

The main consideration is returning
correct results under any type of 
conditions. Mainly, the output or
results observed of an API are divided 
into three sections as follows:
• Returning the result status 
values as ‘Pass’ or ‘Fail’.
• Result as data or any specific
information.
• An event where the call to any 
API function will initiate the call to 
another API function
