java如何只对一种测试方法执行AfterMethod

Question

我必须在我的代码中使用Test方法，我只想为一个方法执行AfterMehtod。有人知道怎么做吗

这是我的代码：

package Demo;

import java.util.concurrent.TimeUnit;

import library.Utility;

import org.openqa.selenium.By;
import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.Test;

import Pages.custom_actions_page;

import com.relevantcodes.extentreports.ExtentReports;
import com.relevantcodes.extentreports.ExtentTest;
import com.relevantcodes.extentreports.LogStatus;

public class Custom_Actions extends start {

    ExtentReports report;
    ExtentTest logger;
    String driverPath = "D:\\geckodriver-v0.16.1-win64\\geckodriver.exe";

    @Test()
    public void signin() throws Exception {

        // To Locate the Username field
        driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
        driver.findElement(By.id("username")).sendKeys("admin");

        // To locate the Password field
        driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
        driver.findElement(By.id("password")).sendKeys("admin123");

        // Click on Login button
        driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
        driver.findElement(By.id("submit")).click();

    }

    @Test(dependsOnMethods = { "signin" })
    public void create_custom_action() {
        report = new ExtentReports("D:/Reports/Report.html");

        logger = report.startTest("Create Custom Action");

        new custom_actions_page(driver).submit();

        new custom_actions_page(driver).admin();

        new custom_actions_page(driver).custom_ac();

        new custom_actions_page(driver).createnew();

        new custom_actions_page(driver).nameAs("fortesting").descriptionAs(
                "description");

        new custom_actions_page(driver).category();

        new custom_actions_page(driver).assetsubtype();

        new custom_actions_page(driver).assettype();

        new custom_actions_page(driver).flintnameAs("hello:example.rb");

        new custom_actions_page(driver).submit_butto();

        new custom_actions_page(driver).Save_Button();

        logger.log(LogStatus.PASS, "Custom Action Created Successfully");
    }

    @AfterMethod()
    public void tearDown(ITestResult result) {

        // Here will compare if test is failing then only it will enter into if
        // condition
        if (ITestResult.FAILURE == result.getStatus()) {
            try {

                Utility.captureScreenshot(driver, "CustomActionFail.png");

            } catch (Exception e) {
                System.out.println("Exception while taking screenshot "
                        + e.getMessage());
            }
        }

        report.endTest(logger);
        report.flush();
        driver.close();
    }}

Answer 1

@AfterMethod的设计目的是，当您需要在每次测试后执行相同的代码块，而不必在每次测试中重复代码块时，您的生活会更轻松。因此，如果只需要在一次测试之后执行，只需将其嵌入@Test方法中，并删除@AfterMethod注释的方法

Answer 2

有几种方法可以使用TestNG中的Native Injection来实现。有关TestNG中本机注入的可能组合的更多详细信息，请参阅here

最简单的方法是从@AfterMethod注释的方法中检查即将执行的@Test方法的名称，如果它与需要特殊执行的方法的名称匹配，则继续执行，否则跳过执行@AfterMethod。 但这是一种原始的方法，因为如果您将测试方法的名称重构为其他名称，您的方法就会被破坏

另一种方法是基本上使用标记接口，并执行与上述相同的逻辑

下面是一个例子，展示了所有这些都在起作用

标记注释如下所示

import java.lang.annotation.Retention;
import java.lang.annotation.Target;

@Retention(java.lang.annotation.RetentionPolicy.RUNTIME)
@Target(java.lang.annotation.ElementType.METHOD)
public @interface NeedsSpecialSetup {
}

现在，您的测试类将如下所示

import org.testng.annotations.AfterMethod;
import org.testng.annotations.Test;

import java.lang.reflect.Method;

public class SampleTestClass {

    @NeedsSpecialSetup
    @Test
    public void testMethod1() {
        System.err.println("Executing testMethod1()");
    }

    @Test
    public void testMethod2() {
        System.err.println("Executing testMethod2()");
    }

    @AfterMethod
    public void afterMethod(Method method) {
        NeedsSpecialSetup needsSpecialSetup = method.getAnnotation(NeedsSpecialSetup.class);
        if (needsSpecialSetup == null) {
            //Don't execute this setup because the method doesn't have the
            //special setup annotation.
            return;
        }
        System.err.println("Running special setup for " + method.getName() + "()");
    }
}

请注意，我们如何仅为方法testMethod1()添加注释@NeedsSpecialSetup，以指示我们只需要为testMethod1()执行@AfterMethod

这是输出

Executing testMethod1()

Running special setup for testMethod1()
Executing testMethod2()
