cucumber, 重新执行失败的用例

做自动化测试的时候，我们经常会出现因为环境或者数据问题导至用例失败，如何能简便快速地重新跑这些case呢？这时候我们就可以加一个很重用的config [rerun]到runer里面了.

如下所示，我们需要在runner里加入["rerun:target/failed_rerun.txt"]，这样每次结束之后我们可以在target里面找到failed_rerun.txt, 里面就记录了哪些test cases是执行失败的。

package com.example.demoForCucumber;

import com.example.demoForCucumber.config.PrettyCucumberReport;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.AfterClass;
import org.junit.Test;
import org.junit.runner.RunWith;


@RunWith(Cucumber.class)
@CucumberOptions(
		tags = {"@API"},
		features = {"src/main/resources/features"},
		glue = {"com.example.demoForCucumber"},
		plugin = {
				"pretty",
				"html:target/cucumber",
				"json:target/cucumberReportJsonFiles/cucumber-report.json",
				"rerun:target/failed_rerun.txt"
		}
)
public class DemoForCucumberApplicationTests {

	@AfterClass
	public static void generateReport(){
		PrettyCucumberReport prettyCucumberReport = new PrettyCucumberReport();
		prettyCucumberReport.generateCucumberReport();
	}

}

 然后我们再建一个FailedReRun runner来执行这些case 即可, 代码如下：

package com.example.demoForCucumber;
/*
 * @author Helen Lee
 * @create 2023/4/9
 * @description: rerun those failed test case
 */

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

@RunWith(Cucumber.class)
@CucumberOptions(
        features = {"@target/failed_rerun.txt"},
        glue = {"com.example.demoForCucumber"},
        plugin = {
                "pretty",
                "html:target/cucumber",
                "json:target/cucumberReportJsonFiles/cucumber-report.json",
                "rerun:target/failed_rerun.txt"
        }
)
public class FailedReRun {
}
