How can I run test cases in parallel using Keyword Driven Framework

Question

Hi All,

I'm using Keyword Driven Framework.

I've 3 classes

1.@Test method to run the tests
2.Driver Script to maintain all Keywords related conditions
3.FUnction Library to maintain all actionMethods and Functional related methods. Ex : EnterText,SelectDropDowns

Maintaining steps in Excel sheets with Test Case wise.

Script will run ,By Making TC number status as "Y",If "N" in master test cases sheet ,nothing will execute

Can any one provide ,how to run Multiple Tests parallely By making multiple tests as "Y" Ex : 5 test cases.

Answer 1

One solution to try for executing test cases in parallel using a keyword driven framework can be :

1. Have a master sheet of cases to execute, which acts as your suite.
2. Have your dataprovider read this master sheet and have a single @Test method which takes in the arguments of the testcase data. This testcase basically reads the steps and executes - something like your ReadAnExecureTestCase method.
3. Make this dataprovider parallel and control using dataprovider thread count.

Can you please provide the code becasue same answer i've seen in Stackoverflow,they have not given any clear examples.

Hey could you try something like this:

public class DriverScript {

List<String> testcase;

@Factory(dataProvider = "testCases")
public DriverScript(List<String> testcase) {
    this.testcase = testcase;
}


@Test
public void runTestCase() {
  // change this method run single with List<String>. Previously you passed  List<List<String>> 
  DriverScript.prepareKeywords(testcase);
}

@DataProvider
public Object[][] testCases(ITestContext context) throws InterruptedException {
    excelUtilities eu = new excelUtilities();

    Properties gldata = new Properties();
    InputStream input = new FileInputStream("src/executionEngine/config.properties");
    gldata.load(input);

    List<List<String>> testcases = new ArrayList<List<String>>();
    testcases = eu.getTestCases(gldata.getProperty("WB_PATH_TESTS"), gldata.getProperty("WB_PATH_TESTS_SHEET"));

    List<List<String>> testcases = new ArrayList<>();
    Object[][] testCasedata= new Object[testcases.size()][1];
    for (int i = 0; i < testcases.size() ; i++) {
        testCasedata[i][0]=testcases.get(i); 
    }
    return testCasedata;
}

To run the above test with parallel=instances, we have to create testuite xml like below and run testng using this xml suite,

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="KeywordDrivenSuite" thread-count="2" parallel="instances"
    preserve-order="true" configfailurepolicy="continue">
    <test name="KeywordDrivenTest">
        <classes>
            <class
                name="com.package.DriverScript" />
        </classes>
    </test>
</suite>

Hi ,i tried the same code but facing problem at dataprovider method,it is not reading the data getting nullpointer exception.

can you please provide "eu.getTestCases" method code.

Hey could you please post the error you are getting?

Hey Hi..

I am facing a similar challenge. I want to pick the test case keywords from testdata excel sheet and carry on the parallel testing. Currently there is only a single @ test method. If you have achieved this. Can you please help me know how you did it?

Thanks in advance!

Hey, have you tried the workarounds as suggested above?
