How to run code before/after cucumber suite?

问题

I'm trying to figure out how to run some code before and after all my cucumber tests run.

I've been tracking down a bug for a few days where some our processes create jobs on a server, and don't properly clean it up. It's easy to miss so ideally I don't want engineers to have to manually add a check to every test.

I was hoping there'd be a way to put a hook in before any tests ran to cache how many jobs exist on the server, then a hook at the end to ensure that the value hasn't changed.

I know this isn't really the best way to use cucumber, as that is more of a system test type thing to do, but doing it this way would be the best way to fit it into the existing infrastructure.

How about using tagged hooks.

@Before("@jobCheck")
public void beforeScenario() {
  // actions
}

@After("@jobCheck")
public void afterScenario() {
  // actions
}

And then for each scenario that requires this check, add @jobCheck before the Scenario definition as below.

Feature: Some feature description
  @jobCheck
  Scenario: It should process a sentence
    // The steps

Use @BeforeClass and @AfterClass annotations in your run file.

@RunWith(Cucumber.class)
@Cucumber.Options(
    format = {"json", "<the report file>"},
    features = {"<the feature file>"},
    strict = false,
    glue = {"<package with steps classes>"})
public class TestRunFile { 
    @BeforeClass
    public static void getJobNumbersOnServerBeforeStarting() {
        //Implement logic
    }

    @AfterClass
    public static void getJobNumbersOnServerAfterCompletion() {
        //Implement logic
    }
}
