如何解决“@BeforeSuite 带注释的启动浏览器不支持本机注入”

问题描述 投票：0回答：1

我在使用 selenium、TestNG 框架启动 chrome 驱动程序时遇到错误。尝试了多种方法，但测试用例失败并一直跳过它。这是我的第一个项目，所以我一无所知。错误日志

这是代码中出现问题的根本原因

@SuppressWarnings("deprecation")
@BeforeSuite
public void launchbrowser(String driverlocation) throws IOException { }

方法

launchbrowser()
有一个参数。

TestNG 在尝试调用带注释的 

driverlocation
@BeforeSuite
 时不知道如何传递参数
launchbrowser()

的值

您应该删除此方法参数。

如果您希望从套件文件中检索 

driverlocation
的值，那么您可以执行如下操作：

import org.testng.ISuite;
import org.testng.Reporter;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

import java.util.Optional;

public class SampleTestCase {

    @BeforeSuite
    @Parameters({"driver"})
    public void beforeSuiteVariant1() {
        ISuite suite = Reporter.getCurrentTestResult().getTestContext().getSuite();
        Optional.ofNullable(suite.getParameter("driver"))
                .ifPresent(it ->
                        System.err.println("Driver retrieved programmatically: " + it));
    }

    @BeforeSuite
    @Parameters({"driver"})
    public void beforeSuiteVariant2(String driver) {
        System.err.println("Driver retrieved via mandatory parameter in suite file: " + driver);
    }

    @BeforeSuite
    @Parameters({"driver"})
    public void beforeSuiteVariant3(@org.testng.annotations.Optional String driver) {
        System.err.println("Driver retrieved via optional parameter in suite file: " + driver);
    }

    @Test
    public void testMethod() {}
}

现在，当您从 IDE 中运行上述测试类（不使用套件文件）时，您会注意到 TestNG 将在 

beforeSuiteVariant2
上出错，因为此方法需要从套件文件中强制注入一个参数。 当您从 IDE 中运行测试时，TestNG IDE 插件（IntelliJ 和 Eclipse）将动态创建一个套件文件，该文件将不包含 
driver
参数
and thus
beforeSuiteVariant2` 将失败。

但是如果您创建一个如下所示的套件文件：

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="my_suite" verbose="2">
    <parameter name="driver" value="chromedriver"/>
    <test name="my_test">
        <classes>
            <class name="com.rationaleemotions.so.qn77995590.SampleTestCase"/>
        </classes>
    </test>
</suite>

您将看到如下所示的输出：

...
... TestNG 7.9.0 by Cédric Beust ([email protected])
...

Driver retrieved programmatically: chromedriver
Driver retrieved via mandatory parameter in suite file: chromedriver
Driver retrieved via optional parameter in suite file: chromedriver
PASSED: com.rationaleemotions.so.qn77995590.SampleTestCase.testMethod

===============================================
    my_test
    Tests run: 1, Failures: 0, Skips: 0
===============================================

要记住的要点：

  • @BeforeSuite
    带注释的方法可以有一个参数，前提是您使用 TestNG 中的 
    @Parameters
    注释。这样，TestNG 就知道它应该在 
    <parameters>
    级别（不在 
    <suite>
    级别内）读取套件文件的 
    <test>
    标记，并使用该值作为参数传递给方法。
  • 本机注入是指 TestNG 自行计算出要作为方法参数传递的内容，而无需您告诉它如何获取这些值。请参阅此处的官方文档，了解有关哪些内容可以通过、哪些内容不能通过的更多详细信息。
  • 如果您想为 
    @BeforeSuite
    方法的参数定义默认行为，即您想告诉 TestNG，请使用套件文件中的参数值（如果存在）。如果它不存在，请不要向我抱怨，而是使用默认值，那么您应该使用
    beforeSuiteVariant1()
    （或）
    beforeSuiteVariant3()
    • 中所示的变体之一

我认为您不再需要管理 selenium webdriver 位置。如果您使用的是最新的 selenium 4.x 系列（我认为今天最新发布的版本是 

4.17.0
），那么 Selenium Manager 会自动为您执行此操作。您只需确保执行以下操作：

  • 搜索属于 
    PATH
    变量一部分的所有位置，并确保从这些位置删除所有 
    chromedriver|edgedriver|geckodriver
    二进制文件。
  • 扫描您的代码库并删除所有执行此类操作的代码片段
    System.setProperty("webdriver.gecko.driver",Driverlocation);
