BDD自动化测试框架cucumber(1): 最基本的demo

BDD（Behavior Driven Development），行为驱动开发, 对应自动化测试框架，python有behave，java有cucumber, 这次记录cucumber+springboot+maven的自动化测试框架。

基本结构如下：

    </build>

</project>

 

2）features: 最重要的环节，用户场景

@login
Feature: login function

  Scenario Outline: password checking
    Given I have open the login page
    And input account=<account>
    And input password=<password>
    When I click the LOGIN button
    Then it return login success to me

    Examples:
    |account|password|
    |user1  |password1|
    |user2  |password2|

3）steps: 实现feature 里面每一个步骤的逻辑，一句话对应一个step一个方法

备注：这里我还没有加上方法体，以后再加

package steps;
/*
 * @author Helen Lee
 * @create 2020/9/11
 * @description
 */
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;
import org.junit.Assert;

public class login_steps {
    @Given("I have open the login page")
    public void iHaveOpenTheLoginPage() {
    }

    @Given("input account=(.*)")
    public void inputAccountAccount(String account) {

    }

    @Given("input password=(.*)")
    public void inputPasswordPassword(String password) {

    }

    @When("I click the LOGIN button")
    public void iClickTheLOGINButton() {

    }

    @Then("it return login success to me")
    public void itReturnLoginSuccessToMe() {
    }
}

4）runner: 执行testcases

/*

 * @create 2020/9/11
 * @description
 */

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;

@RunWith(Cucumber.class)
@SpringBootTest
@CucumberOptions(
        tags = {"@login"},
        features = {"src/main/resources/features"},
        glue = {"steps"},
        plugin = {
                "pretty",
                "html:target/cucumber",
                "json:target/cucumberReportJsonFiles/cucumber-report.json"
        }
)
public class demoRunner {
    public void test() {
    }
}

 

完成这四个之后，就可以run demoRunner了，结果如下：跑了user1/password1 和user2/passwords两个test cases
