Gherkin: .feature can't find a .step definition when it uses a parametertype on it

[maioni]

👓 What did you see?

The .feature file (the gherkin) cant find the step definition when it's using a @parametertype value on it.

Files content

.feature Feature: Pages I want to use the menu page

Scenario: Click on menu Given I click on menu

.step @Then("I click on {menu}")

@ParameterType("menuitema|menuitemb|menuitemc") public String menu(String menu) { if ("menuitema|menuitemb|menuitemc".contains(menu)) { return menu; } return ""; }

✅ What did you expect to see?

The Gherkin should find the step definition, and the step definition should found the parameter type definition, this way we can CTRL + CLICK on feature to goes to the step definition.

📦 Which tool/library version are you using?

Eclipse + Eclipse Cucumber Plugin

🔬 How could we reproduce it?

Steps to reproduce the behavior:

1. Install 'Eclipse IDE for Enterprise Java and Web Developers (includes Incubating components)' Version: '2022-03 (4.23.0)' Build id: '20220310-1457'
2. Create a Maven Project
3. Install the 'Eclipse Cucumber Plugin' version '1.0.0.202106240526' at 'Eclipse Marketplace'
4. Convert the project to Cucumber: Open the contextual menu from your project - right click - Configure > Convert as cucumber project…
5. Clean project: Project > Clean…
6. Open the .feature file
7. Hold CTRL and click on the feature to goes to the step definition location

at Eclipse: Help > Install New Software

Add Name: Cucumber Eclipse Plugin 2.0 Location: https://cucumber.github.io/cucumber-eclipse/update-site/main/ Add

Select Cucumber Eclipse Plugin, Ansi Console, third party dependencies Next

If 1.0 was installed, it will be updated to 2,0 instead:

Select All Trust Selected

Restart Now

PROBLEM! After install 2.0, the options to convert project to cucumber is absent, and .feature files are no more associated to cucumber: @laeubi

I tried to install 2.0 after 1.0 to upgrade it, but the issue remains, and I couldn't associate .feature to cucumber properly:

Steps: Install Cucumber Eclipse Plugin 1.0 Restart Eclipse

At Project, select it with right click and Configure > Convert to Cucumber Project... [OPTION ABSENT WITH 2.0, ONLY AVAILABLE WITH 1.0]

Select Project and Clean...

Now the feature and steps are correctly linked. [ONLY WORKED WITH 1.0 BUT NOT COMPATIBLE WITH CUCUMBER 6/7 NEW FEATURES LIKE PARAMETER TYPE, UNABLE TO DO IT WITH 2.0 DUE TO PREVIOUSLY ISSUES]

[laeubi]

PROBLEM! After install 2.0, the options to convert project to cucumber is absent,

2.0 do not use/require a special project type anymore. Please make sure that 1.0 is uninstalled and there are no conflicting editor assignments that take precedence.

[laeubi]

Also make sure to use a recent eclipse version.

Using the last version, and already installed 2.0 alone, the issue remains.

[laeubi]

There is an example project here:

https://github.com/cucumber/cucumber-eclipse/tree/main/examples/java-calculator

this requires m2eclipse to be imported and then should work at least last time i tested, if not please open an issue with the steps to reproduce the problem.

[maioni]

Downloaded a new and updated Eclipse with already m2 installed: But the issue remains, after install Cucumber Eclipse Plugin, the files .feature remains not associated, and the Convert project to cucumber absent.

Same issue with the example project:

@laeubi the issue is open: https://github.com/cucumber/cucumber-eclipse/issues/459

Same issue with the example project:

Sorry I don't understand, your screenshot shows the green cucumber icon for the feature and it open a gherking / cucumber editor with highligts and instant run actions so what exactly are you missing?

After know how to install Cucumber Eclipse Plugin 2.0, and now able to test a cucumber project that uses Parameter type, the feature remains unable to find the step definition:

Updating the example calculator code to support parametertype: Original code: https://github.com/cucumber/cucumber-eclipse/tree/main/examples/java-calculator Updated code with parametertype implemented: java-calculator.zip

Looking at these files:

• Feature /java-calculator/src/test/resources/io/cucumber/examples/calculator/basic_arithmetic.feature
• Step /java-calculator/src/test/java/io/cucumber/examples/calculator/RpnCalculatorSteps.java

And updating the step code at line 19:

• From:

  @Given("a calculator I just turned on")
  public void a_calculator_I_just_turned_on() {
      calc = new RpnCalculator();
  }

  

• To:

  
  import io.cucumber.java.ParameterType;

...

@Given("a calculator I just turned {power}") public void a_calculator_I_just_turned_on(String power) { switch (power) { case "on": calc = new RpnCalculator(); break; } }

@ParameterType("on|off")
public String menu(String power) {
    if ("on|off".contains(power)) {
        return power;
    }
    return "";
}

[laeubi]

According to your screenshot you have not saved the RnpCalculatorStep file...

Beside that its best to enhance the example (or copy it, provide an own, ...) open a PR and a separate issue.

You want me to update the example code in github, that's it? Close this issue and open a new one?
