Will Cucumber Java 8 runs outside constructor ?

[mmaryo]

Hello,

I would like to use the Cucumber Java 8 lambda expressions

Like this : https://cucumber.io/docs/reference/jvm

public class ShoppingStepsDef implements En {
 
    private int budget = 0;
 
    public ShoppingStepsDef() {
	Given("I have (\\d+) in my wallet", (Integer money) -> budget = money);
 
	When("I buy .* with (\\d+)", (Integer price) -> budget -= price);
 
	Then("I should have (\\d+) in my wallet", (Integer finalBudget) -> 
	  assertEquals(budget, finalBudget.intValue()));
    }
}

This syntax is amazing, but runs inside constructor there are problems :

• we cannot run @before and @after methods of JUnit

• we cannot instantiate Spring context with @Autowired

Have you got a plan about that ?

Regards

Will Cucumber Java 8 runs outside constructor?

Given the current possibilities of Java 8 no. Perhaps with Java 9 we could use the repl but somebody will have to feel like building it.

we cannot run @before and @after methods of JUnit

Are you certain you do not have these confused with cucumbers @Before and @After? To wit cucumber-junit will only pick up on junits @BeforeClass, @AfterClass and @ClassRule in the runner class. The java8 equivalent of @Before is Before(() -> { // do stuff}); Its various method definitions are located in the parent class of En.

We cannot instantiate Spring context with @Autowired

Please check your implementation against the spring-txn example. If the problem persists please create a minimal complete verifiable example.

Do keep the caveat emptor of How soon will my ticket be fixed? in mind though.

Edit: Yes, the example is written using only annotations but @AutoWired will function the same regardless. To wit using dependency injection through the constructor also works.
