How can i run feature files with testng suite xml in parallel?

[qaschevychelov]

Hi! I've faced such problem: I'm using 'cucumber-jvm-parallel-plugin' for parallel running feature files. But this approach create JVM per test runner. I decided to use testNG suite xml file, in which i link test runners. But in test runner i need to initialize TestNGCucumberRunner.

If i pass this.getClass() in the TestNGCucumberRunner constructor, then it will throw "[TestNG] WARN cucumber.runtime.SerenityBackend - It looks like you are running a feature using @RunWith(Cucumber.class) instead of @RunWith(CucumberWithSerenity.class). Are you sure this is what you meant to do?"

If i pass CucumberWithSerenity.class in the TestNGCucumberRunner constructor, then it will throw "None of the features at [classpath:net/serenitybdd/cucumber] matched the filters: [@ready]". I think i need somehow to switch classpath from classpath:net/serenitybdd/cucumber to a valid one.

Where did i go wrong?

My suite xml:

Serenity will only work with the JUnit runner

[qaschevychelov]

i managed to run tests with testng suite xml. I removed a line "@RunWith(CucumberWithSerenity.class)" and pass this.getClass() in the TestNGCucumberRunner constructor. All scenarios go to the Selenium Grid hub. But the hub passes all scenarious to one appium node every time. If i use parallel approach with "cucumber-jvm-parallel-plugin", then selenium grid hub passes scenarious correctly to nodes.

[wakaleo]

I'm not sure if this will work - the CucumberWithSerenity sets up Serenity, so if you don't have it, Serenity won't be enabled. Does the this.getClass() replace this?

[qaschevychelov]

No this.getClass() refers to Cart class. Cart is a testNG runner. In this class i use methods with following annotations: @BeforeClass @Test @DataProvider @AfterClass (from testNG). DataProvider method (barcodes) return all feature files from path "src/test/resources/features/cart" into the method with Test annotation. And @Test method run all scenarious in all feature files. I investegated that when i use TestNGCucumberRunner, JUnit annotation @RunWith is omitted in test runner. But somehow (i dont understand how) first scenario goes to one appium node and runs correctly
