API Testing / REST Assured Automation Testing Advice and or suggestions - json

Question

Really looking for some practical advice and general guidance.
Below is the current scenario.
I have an excel document each row would be considered a test with inputs.
There would be hundreds if not thousands of rows.
Lets for example say Row1 would look like
Col1----------|Col2---------------|Col3
TestingUser|TestingSurname|1980/01/01
This needs to me mapped to a JSON object then sent / POST to an API end point.
I then need to assert the data that is coming back to make sure it’s the correct values.
The tools I have looked at is:
ReadyAPI
rest-assured.io
Would you recommend any other tool or framework for this type of testing.
If you have worked with something and you can provide an example that would be great.

Answer 1

I wouldn't be able to provide recommendation as i haven't worked on RestAssured.However below are few advantages of ReadyAPI:
Learning curve is shallow,any Tester will be able to build test
case without dependency on any programming language. ReadyAPI has
inbuild feature to read data from different datasources(DB, XML,
json,csv,excel etc.) and invoke REST endpoint by passing these
fields to Header,query and Json Body of the end point.
The response for each call can be dumped to a file using DataSink option for a
test step for each of the request calls made for the records from the file.
Tool is structured to easily build test Cases with multiple test
Steps. It more like drag and drop to build your test cases.Hierarchy
is Project -> Test Suite -> Test Case -> Test Step.
Easy integration with Jenkins CI/CD pipeline using testRunner with wide
variety of test reporting capabilities. Test reports are available as Allure,
jasper reports, junit Style reporting.
For more technical testers who need more control can use Groovy,javascript
language to build frameworks.
VirtServer and LoadUI are other tools by SmartBear that can be used to mock
services and run performance tests as desired.
I have an important comment to make here, if the file is huge(even 1000 lines) i have seen Ready API struggling as the tool does the heavylifting in the back. Hence would recommend to use groovy script utilizing Java API's for any file operations.

Ok so I have created a class using velocity as a json template engine.
I have created a test and within that test i have a normal java loop.
This will loop through the entire xls, map values and and post to the API.
This is all working as expected.
The problem is the runner displays
Default Suite
Total tests run: 1, Passes: 0,
However the loop does run x amount of times.
How can i update it the when i execute the test its shows total tests run 10 or the same amount that is from the loop.
Hope this makes sense
#Test
public void generatePostData() throws IOException {
Workbook wb = WorkbookFactory.create(new File("data\\sc1.xlsx"));
Sheet sheet = wb.getSheetAt(0);
for (int i = 1; i < 10; i++) {
//Get Excel Data
Cell testNumber = sheet.getRow(i).getCell(1);
System.out.println(testNumber.getNumericCellValue());
//Velocity
VelocityEngine ve = new VelocityEngine();
ve.init();
//get the template
Template t = ve.getTemplate("post.json");
//create context and add data
VelocityContext context = new VelocityContext();
//map data
context.put("tpltestNumber", testNumber);
//render to stringWriter
StringWriter writer = new StringWriter();
t.merge(context, writer);
baseURI = "someURL";
Response response =
given()
.contentType("application/json")
.body(String.valueOf(writer))
.when()
.post()
.then()
.assertThat()
.statusCode(200)
.extract()
.response();
}
}

This is the answer to the question asked in the answers sesction by the reporter of the main question. (How to get the executed excel row count, for total executed test case count)
For that you have to pass the data using a method with DataProvider annotation.
TestNG documentation
DataProvider in TestNG
#DataProvider(name = "dp")
private Object[][] dataProvider() {
Workbook wb;
Sheet sheet = null;
Object[][] excelRowArray = new Object[10][]; //this 10 the row count in the excel file
try {
wb = WorkbookFactory.create(new File("data\\sc1.xlsx"));
sheet = wb.getSheetAt(0);
} catch (IOException e) {
e.printStackTrace();
}
for (int i = 1; i < 10; i++) {// Here 10 is the row count in the excel sheet
//Get Excel Data row by row
Cell testNumber = sheet.getRow(i).getCell(1);
System.out.println(testNumber.getNumericCellValue());
// Create a object array with the values taken from a singe excel row
Object[] excelRow = new Object[]{testNumber};
// Add the created object array to the 'excelRowArray'
excelRowArray[i - 1] = excelRow;
}
return excelRowArray;
}
#Test(dataProvider = "dp")
public void generatePostData(Object[] excelRow) {
// Here single excelRow will be passed each time.
// And this will run till all object[] in excelRowArray are finished.
// Total tests executed will be the number of 'excelRow' object arrays in
// excelRowArray. (Or excel row count in the sheet)
//Velocity
VelocityEngine ve = new VelocityEngine();
ve.init();
//get the template
Template t = ve.getTemplate("post.json");
//create context and add data
VelocityContext context = new VelocityContext();
//map data
context.put("tpltestNumber", excelRow); // Here excelRow is used as the value
//render to stringWriter
StringWriter writer = new StringWriter();
t.merge(context, writer);
String baseURI = "someURL";
Response response =
given()
.contentType("application/json")
.body(String.valueOf(writer))
.when()
.post()
.then()
.assertThat()
.statusCode(200)
.extract()
.response();
}
