Refactor Java code safely — and automatically — with OpenRewrite.

Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.

Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.

Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.

Regression testing is an important step in the release process, to ensure that new code doesn't break the existing functionality. As the codebase evolves, we want to run these tests frequently to help catch any issues early on.

The best way to ensure these tests run frequently on an automated basis is, of course, to include them in the CI/CD pipeline. This way, the regression tests will execute automatically whenever we commit code to the repository.

In this tutorial, we'll see how to create regression tests using Selenium, and then include them in our pipeline using GitHub Actions:, to be run on the LambdaTest cloud grid:

1. Introduction

In this tutorial, we’ll learn how to run or skip Scenarios selectively in Cucumber.

Cucumber is a tool that supports Behaviour-Driven Development (BDD). It reads executable specifications in plain text and validates that the software does what those specifications say.

2. Creating Scenarios

First, let’s create a few scenarios.

Let’s take an example of an API endpoint /greetings that generates a greeting message. We can write the following scenarios for it:

Feature: Time based Greeter
    # Morning
    Scenario: Should greet Good Morning in the morning
        Given the current time is "0700" hours
        When I ask the greeter to greet
        Then I should receive "Good Morning!"
    # Evening
    Scenario: Should greet Good Evening in the evening
        Given the current time is "1900" hours
        When I ask the greeter to greet
        Then I should receive "Good Evening!"
    # Night
    Scenario: Should greet Good Night in the night
        Given the current time is "2300" hours
        When I ask the greeter to greet
        Then I should receive "Good Night!"
    # Midnight
    Scenario: Should greet Good Night at midnight
        Given the current time is "0000" hours
        When I ask the greeter to greet
        Then I should receive "Good Night!"

Let’s now implement a controller method that generates a response as per the above specification:

@GetMapping("/greetings")
@ResponseBody
public String greet(@RequestParam("hours") String hours) {
    String greeting;
    int currentHour = Integer.parseInt(hours.substring(0, 2));
    if (currentHour >= 6 && currentHour < 12) {
        greeting = "Good Morning!";
    } else if (currentHour >= 12 && currentHour < 16) {
        greeting = "Good Afternoon!";
    } else if (currentHour >= 16 && currentHour <= 19) {
        greeting = "Good Evening!";
    } else {
        greeting = "Good Night!";
    }
    return greeting;
}

3. Approaches

Now, we’re ready to see how to ignore one or more of the scenarios we just defined.

3.1. Tagging With a Custom Tag

In this approach, we annotate our Scenarios with a custom annotation. It can be any string of our choice, e.g., @ignore, @skip or @disable. Let’s take something completely random say @custom-ignore to confirm that it doesn’t matter what we choose. However, something meaningful is a better choice.

Now, it’s a two-step process. First, we’ll mark the scenario with the annotation. Let’s mark the third scenario with this annotation:

# Night
@custom-ignore
Scenario: Should greet Good Night in the night
    Given the current time is "2300" hours
    When I ask the greeter to greet
    Then I should receive "Good Night!"

Then, we’ll need to add the property cucumber.filter.tags in junit-platform.properties under the test resources folder:

cucumber.filter.tags=not @custom-ignore

And that’s it. This scenario will now be ignored in the subsequent test runs.

Notably, if we’re using Junit4, the same configuration needs to be specified using the @CucumberOptions annotation on a Cucumber TestRunner class:

@CucumberOptions(tags = "not @custom-ignore")

Additionally, we can also run only selective tags.

3.2. Commenting out the Scenario

It’s worth noting that there are other options too, but they may not be as idiomatic as the first approach.

One such approach is to comment out the scenario:

# Night
#  Scenario: Should greet Good Night in the night
#      Given the current time is "2300" hours
#      When I ask the greeter to greet
#      Then I should receive "Good Night!"

However, this is error-prone as we might overlook commenting and uncommenting multiple lines.

4. Conclusion

In this article, we examined how using custom tags/annotations, we can reliably ignore one or more Scenarios in Cucumber.

Notably, Cucumber allows flexible tags to annotate and skip Scenarios. While we explored other options too, we learned that using a tag-based approach is the idiomatic way to achieve this goal.

Modern Java teams move fast — but codebases don’t always keep up. Frameworks change, dependencies drift, and tech debt builds until it starts to drag on delivery. OpenRewrite was built to fix that: an open-source refactoring engine that automates repetitive code changes while keeping developer intent intact.

The monthly training series, led by the creators and maintainers of OpenRewrite at Moderne, walks through real-world migrations and modernization patterns. Whether you’re new to recipes or ready to write your own, you’ll learn practical ways to refactor safely and at scale.

If you’ve ever wished refactoring felt as natural — and as fast — as writing code, this is a good place to start.
