java - 在 Cucumber-jvm 中使用多个步骤定义时出现 NullPointerException

Question

我目前正在构建一个框架来测试 Rest-API 端点。由于我计划编写大量测试用例，因此我决定组织该项目以允许我重用常见的步骤定义方法。

结构如下；

FunctionalTest
    com.example.steps
        -- AbstractEndpointSteps.java
        -- SimpleSearchSteps.java
    com.example.stepdefinitions
        -- CommonStepDefinition.java
        -- SimpleSearchStepDefinition.java`

但是，当我尝试调用 SimpleSearchSteps.java 方法时，我收到 NullPointerException

CommonStepDefinition代码

package com.example.functionaltest.features.stepdefinitions;

import net.thucydides.core.annotations.Steps;

import com.example.functionaltest.steps.AbstractEndpointSteps;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;


public class CommonStepDefinition {

    @Steps
    private AbstractEndpointSteps endpointSteps;

    @Given("^a base uri \"([^\"]*)\" and base path \"([^\"]*)\"$")
    public void aBaseUriAndBasePath(String baseURI, String basePath) {
        endpointSteps.givenBasepath(baseURI, basePath);
    }

    @When("^country is \"([^\"]*)\"$")
    public void countryIs(String country) 
    {
        endpointSteps.whenCountry(country);
    }

    @Then("^the status code is (\\d+)$")
    public void theStatusCodeIs(int statusCode) {
        endpointSteps.executeRequest();
        endpointSteps.thenTheStatusCodeIs200(statusCode);
    }

}

SimpleSearchStepDefinition.java

package com.example.functionaltest.features.stepdefinitions;

import net.thucydides.core.annotations.Steps;
import com.example.functionaltest.steps.EndpointSteps;
import cucumber.api.java.en.When;


public class SimpleSearchStepDefinition {

    @Steps
    private SimpleSearchSteps searchSteps;



    @When("^what is \"([^\"]*)\"$")
    public void whatIs(String what) {
        searchSteps.whenWhatIsGiven(what);
    }

}

看起来您缺少 Cucumber 注释的持有者类，您应该拥有这样的东西，以便 Cucumber 知道并识别您的步骤和功能:

@RunWith(Cucumber.class)
@CucumberOptions(
    glue = {"com.example.functionaltest.features.steps"},
    features = {"classpath:functionaltest/features"}
)
public class FunctionalTest {
}

请注意，根据此示例，在您的 src/test/resources 中，您应该具有包含 .feature 文件的功能测试/features 文件夹，您可以根据您的设计更改它
