【问题描述】：
我正在尝试使用非并行的 TestNg 在 Chrome 和 Firefox 中执行我的代码。在第一个测试“Chrome”中正常工作，第二个测试“Firefox”浏览器打开但抛出以下异常 'org.openqa.selenium.NoSuchSessionException: invalid session id'。
org.openqa.selenium.NoSuchSessionException: invalid session id

这是我在 Chrome 完成执行后遇到的异常。 在上述异常中，为 Second Test 传递的浏览器参数仍然是“Chrome”。
TestNg 文件：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" verbose="2">
<test thread-count="5" name="Chrome">
<parameter name="browser" value="Chrome"/>
<!-- <groups>
<run>
<include name="exe.home"/>
</run>
</groups> -->
<classes>
<class name="modules.openBrowser" />
<class name="testCases.testClass"/>
</classes>
</test> <!-- Test -->
<test thread-count="5" name="FireFox">
<parameter name="browser" value="Firefox"/>
<!-- <groups>
<run>
<include name="exe.home"/>
</run>
</groups> -->
<classes>
<class name="modules.openBrowser" />
<class name="testCases.testClass"/>
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
浏览器处理类：
public class openBrowser implements auto_constant{
public static WebDriver driver = null;
@BeforeTest(description = "Checking the browser and launching it")
@Parameters({"browser"})
public void beforeTest(String browser) {
extentReports.attRepo(browser);
if(browser.equalsIgnoreCase("Chrome")) {
WebDriverManager.chromedriver().setup();
if(Property.getProperty("head").equalsIgnoreCase("false")) {
driver = new ChromeDriver();
}else {
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
driver = new ChromeDriver(options);
}
}else if(browser.equalsIgnoreCase("Firefox")) {
driver = null;
WebDriverManager.firefoxdriver().setup();
if(Property.getProperty("head").equalsIgnoreCase("false")) {
driver = new FirefoxDriver();
}else {
FirefoxOptions options = new FirefoxOptions();
options.addArguments("headless");
driver = new FirefoxDriver(options);
}
}
driver.manage().window().maximize();
driver.get(url);
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
}
@AfterTest(description = "Terminating the browser instance and reports")
public void afterTest() {
extentReports.extent.flush();
driver.close();
}
我什至尝试从 WebDriver 中删除“静态”仍然是相同的异常。
谢谢。
【问题讨论】：
-
将firefox代码放在chrome前面，检查chrome是否出现同样的异常
-
我试过了，我得到了这个异常“org.openqa.selenium.NoSuchSessionException: 试图在没有建立连接的情况下运行命令”
