I am very new to Selenium and Cucumber.
I am asking for your kind advice.

I tried to investigate myself and find that import io.cucumber.junit.CucumberOptions; in combination with stepNotifications = true may help. However when I try to add it I am getting: "The import io.cucumber.junit cannot be resolved". Looking forward for your kind advice.

Answer 1

I found an answer here:
Step Definition detection only works when project is configured as cucumber project.- Virtual Machine
Generally speaking:
If the step definition is not happened and the feature file does not highlight undefined steps with amber color that means that the project is not converted as a cucumber project.
Do the following:
In order to convert the project as a cucumber project do the following: Right-click on your project from the Project Explorer > Configure > Convert as Cucumber Project.
Ensure option Enable Step Definitions Glue Detection is checked in Window > Preferences > Cucumber
