Cucumber + IDEA 环境搭建

前提：已安装 idea 、 jdk 1.8
官方安装文档： https://www.jetbrains.com/help/idea/2016.1/cucumber.html?origin=old_help
1 IDEA > File > Setting > Plugins
安装Cucumber for java ; Cucumber for Groovy
2 使用maven新建工程
3 POM文件：

    <dependencies>
        <!-- test support library (page objects, elements, test base, ...) -->
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-java</artifactId>
            <scope>test</scope>
            <version>1.2.5</version>
        </dependency>
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-junit</artifactId>
            <scope>test</scope>
            <version>1.2.5</version>
        </dependency>
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-jvm</artifactId>
            <version>1.2.5</version>
            <type>pom</type>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
    </dependencies>

4 目录结构如下：

准备工作结束，开始写第一个Cucumber测试
1 test/ersources下新建feature文件

# Created by Jane.Yao at 2020/5/22
Feature: Add Test
  Scenario: Add Test
    Given x is 5 and y is 6
    When add x and y
    Then Result is 11

2 test/java下创建Runner文件，用于执行Cucumber测试

package com.cucumber;

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"pretty","json:target/cucumbr-report.json"})
public class CalculatorTestRunner {
}

3 feature文件，alt+enter， 创建step，指定step文件存放路径

4 自动生成的step文件内容

package com.cucumber;

import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;

public class MyStepdefs {
    @Given("^xP is (\\d+) and y is (\\d+)$")
    public void xpIsAndYIs(int arg0, int arg1) {
    }

    @When("^add x and y$")
    public void addXAndY() {
    }

    @Then("^Result is (\\d+)$")
    public void resultIs(int arg0) {
    }
}

5 填充实际操作code

package com.cucumber;

import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;

import static org.hamcrest.core.IsEqual.equalTo;
import static org.junit.Assert.assertThat;

public class MyStepdefs {

    private Calculator calculator;
    private int result;

    @Given("^xP is (\\d+) and y is (\\d+)$")
    public void xpIsAndYIs(int arg0, int arg1) {
        this.calculator = new Calculator(arg0, arg1);
    }

    @When("^add x and y$")
    public void addXAndY() {
        result = this.calculator.add();
    }

    @Then("^Result is (\\d+)$")
    public void resultIs(int arg0) {
        assertThat(result, equalTo(arg0));
    }
}

6 运行runner文件，看与期望结果是否一致

7 附：Calculator文件内容

package com.cucumber;

public class Calculator {
    private int x;
    private int y;
    public Calculator(int x , int y){
        this.x = x;
        this.y = y;
    }
    public int add(){
        return this.x + this.y;
    }
}
