要使用Java编写Cucumber测试用例,您需要遵循以下步骤:

  1. 创建一个Maven项目并添加Cucumber和JUnit依赖项到pom.xml文件中:
<dependencies>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>6.11.0</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-junit</artifactId>
        <version>6.11.0</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter</artifactId>
        <version>5.7.2</version>
        <scope>test</scope>
    </dependency>
</dependencies>
  1. 创建一个.feature文件来定义测试场景和步骤。例如,创建一个名为"calculator.feature"的文件,并添加以下内容:
Feature: Calculator
  Scenario: Add two numbers
    Given I have entered 50 into the calculator
    And I have entered 70 into the calculator
    When I press add
    Then the result should be 120 on the screen
  1. 创建一个Step Definitions类来实现.feature文件中定义的步骤。例如,创建一个名为"CalculatorSteps.java"的类,并添加以下内容:
import io.cucumber.java.en.Given;
import io.cucumber.java.en.When;
import io.cucumber.java.en.Then;

public class CalculatorSteps {
    private int result;
    
    @Given("I have entered {int} into the calculator")
    public void i_have_entered_number_into_the_calculator(int number) {
        // Enter number into the calculator
    }
    
    @When("I press add")
    public void i_press_add() {
        // Press add button
        result = // Perform addition operation
    }
    
    @Then("the result should be {int} on the screen")
    public void the_result_should_be_number_on_the_screen(int expected) {
        // Verify that the result is equal to the expected value
    }
}
  1. 创建一个Test Runner类来运行测试。例如,创建一个名为"TestRunner.java"的类,并添加以下内容:
import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class)
@CucumberOptions(features = "src/test/resources/calculator.feature")
public class TestRunner {
}
  1. 运行Test Runner类以执行Cucumber测试用例。您可以在控制台或IDE中查看测试结果。

这是一个简单的示例,您可以根据您的需求和具体情况进行调整和扩展。希望这些步骤可以帮助您开始使用Java编写Cucumber测试用例。
