Cucumber BDD with Selenium WebDriver and Testng Framework
Cucumber is a Behavior Driven Development (BDD) testing framework that helps the non technical members of the team can easily understand the scenario’s automating by testers. In Cucumber, the feature files plays very important role that contains plain English text written using gherkin language which is easy to understand. Refer to the Cucumber Basics
Cucumber-BDD using Page Object Model and Testng Framework:
1. Create a Maven Project with name as ‘cucumbermvn’. Refer to the steps->
2. Add the following dependencies and plugins required for Cucumber,Selenium,Testng.
Refer to the dependencies for Cucumber – Java project

3. Create a following Directory Structure for the project as mentioned below:
Cucumber – BDD,StepDefs,Selenium,Testng,Page Object Model,Maven
4. Refer to the Functional Tests OpenMRSTests.java as mentioned below:

5. Refer to the Step Definitions file LoginPage.java as mentioned below:

6. Feature file Login.feature contains the steps to be performed as part of the scenario:
|
1 2 3 4 5 6 7 8 9 10 |
Feature: feature name Scenario: Authenication Given Open Application and Enter url When enter username And enter password Then verify Msg |
7. Refer to the testng.xml file.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite name="Suite" verbose="5"> <test name="Test"> <classes> <class name="org.cucumber.tests.OpenMRSTests"/> </classes> </test> <!-- Test --> </suite> <!-- Suite --> |
8. Execute the following maven command with Goals as verify to generate the Cucumber Reports.
mvn verify
Cucumber Reports,CucumberTestReport.json
its deprecated version of cucumber. New version is 3x
suppose we have multiple feature file in same folder and if we want to run each one feature file without hard code in @cucumberoption then how to configure each feature file in testng.xml file.
Hi ,
In the above example we have not hardcorded the feature file name.
So it will pick all the feature files available under the features folder.
features=”src/test/resources/features”
Regards,
total-qa.com
I am using below dependencies getting error
The method getCucumberFeature() is undefined for the type CucumberFeatureWrapper
The method provideFeatures() is undefined for the type TestNGCucumberRunner
Any specific reason why its not working
@Test(groups = “cucumber”,dataProvider=”features”)
public void test(CucumberFeatureWrapper wrapper) throws Exception {
testRunner.runCucumber(wrapper.getCucumberFeature());
}
@DataProvider(name=”features”)
public Object[][] getFeatures()
{
return testRunner.provideFeatures();
}
