要通过 TestNG 运行 Cucumber 功能，请确保完成以下步骤：

1. 包含 Cucumber-testNG 依赖项：https://mvnrepository.com/artifact/io.cucumber/cucumber-testng

2. Cucumber runner 类已创建，例如：

    package testrunners;

    import io.cucumber.testng.AbstractTestNGCucumberTests;
    import io.cucumber.testng.CucumberOptions;

    @CucumberOptions(
            features = "src/test/resources/features",
            glue = {"stepdefinitions"},
            plugin = {
                    "pretty",
                    "json:cucumber.json"
            }
    )
    public class TestRunner extends AbstractTestNGCucumberTests {}

    

该类必须扩展 AbstractTestNGCucumberTests 类
src/test/resources/features 是包含 .feature 文件的文件夹的路径
stepdefinitions 是包的名称，其中包含已实现步骤的代码的类。

3. TestNG XML 运行上述步骤中的 Cucumber 运行程序类，例如：

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
    <suite name="Default Suite" configfailurepolicy="continue" time- 
    out="60000">
        <test name="Main tests">
            <classes>
                <class name="testrunners.TestRunner"/>
            </classes>
        </test>
    </suite>

通过此设置，您应该能够运行 TestNG XML，它将执行位于指定文件夹中的所有 .feature 文件中的所有场景。
