一， 异常截图场景

  • 增加自动化测试代码的可测性
  • 丰富报告

二， 实现原理

  • 异常捕获
  • 自动化关键数据记录
  • 代码示例
import io.qameta.allure.Allure;
import org.apache.commons.io.FileUtils;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.time.Duration;
import java.util.Date;
import static java.lang.Thread.sleep;
import static org.junit.jupiter.api.Assertions.fail;

public class ScreenTest {
    private static WebDriver driver;

    @BeforeAll
    static void setupClass(){
        ChromeOptions options = new ChromeOptions();
        options.addArguments("--remote-allow-origins=*");
        driver = new ChromeDriver(options);
        driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(3));
    }

    @AfterAll
    static void tearDownClass() throws InterruptedException {
        sleep(5000);
        driver.quit();
    }

    void saveScreen() throws IOException {
        //生成时间戳字符串（时间戳太长会报错）
        Date date = new Date();
        long timestamp = date.getTime()/1000;
        //将截图文件保存
        File scfile = new File("./files/" + timestamp + ".png");
        File currentScreen = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        FileUtils.copyFile(currentScreen, scfile);
        //添加到报告附件
        Allure.addAttachment("add_pic","image/png",new FileInputStream(scfile),".png");
    }

    @Test
    void screenTest() throws IOException {
        try{
            driver.get("https://ceshiren.com/");
            // 错误代码
            driver.findElement(By.name("adb"));
        }catch (Exception e){
            saveScreen();
            fail("NoSuchElementException" + e);
        }
    }
}
