在黄瓜测试中使用特征文件中的值？

Question

Is there any way to declare a variable in a feature file to then use in a cucumber test? Something like this:

myFile.feature

Given whenever a value is 50

myFile.java

@Given("^whenever a value is 50$")
public void testing(value) {
    assertEqual(value, 50);
}

Honestly, I don't even know what this would look like. But I would love to not have to declare a value in both the feature file AND the Cucumber test. Thanks!

Answer 1

Yes you can! Write the Given-step in the feature.

Feature: foobar

Scenario: something
    Given whenever a value is 50

Then run it as a JUnit test. You will see something like this in the console.

@Given("^whenever a value is (\\d+)$")
public void whenever_a_value_is(int arg1) throws Throwable {
    // Write code here that turns the phrase above into concrete actions
    throw new PendingException();
}

Then you can copy+paste it and change it to:

@Given("^whenever a value is (\\d+)$")
public void whenever_a_value_is(int value) {
    assertEquals(value, 50);
}
