维护和重用现有webdriver浏览器实例-java
基本上，每次我从eclipse运行java代码时，webdriver都会启动一个新的ie浏览器，并在大部分情况下成功地执行我的测试。然而，我有很多测试要运行，webdriver每次启动一个新的浏览器会话都很痛苦。我需要一种重新使用以前打开的浏览器的方法；所以webdriver会在第一次打开ie，然后第二次，我运行我的eclipse程序，我希望它能够简单地获取以前的浏览器实例，并继续在同一个实例上运行我的测试。这样，我就不会每次运行程序时都启动新的浏览器会话维护和重用现有webdriver浏览器实例-java,java,selenium,selenium-webdriver,browser-automation,remotewebdriver,Java,Selenium,Selenium Webdriver,Browser Automation,Remotewebdriver,基本上，每次我从eclipse运行java代码时，webdriver都会启动一个新的ie浏览器，并在大部分情况下成功地执行我的测试。然而，我有很多测试要运行，webdriver每次启动一个新的浏览器会话都很痛苦。我需要一种重新使用以前打开的浏览器的方法；所以webdriver会在第一次打开ie，然后第二次，我运行我的eclipse程序，我希望它能够简单地获取以前的浏览器实例，并继续在同一个实例上运行我的测试。这样，我就不会每次运行程序时都启动新的浏览器会话 假设您有100个测试要在eclipse
假设您有100个测试要在eclipse中运行，点击run按钮，它们都会运行，然后在大约第87次测试时，您会得到一个错误。然后返回eclipse，修复该错误，但随后必须从头开始重新运行所有100个测试
修复第87个测试上的错误，然后从第87个测试恢复执行，这将是很好的，而不是从头开始重新执行所有测试，即从测试0一直执行到100。 希望我很清楚能得到你们的帮助，谢谢。
下面是我试图维护和重用webdriver internet explorer浏览器实例的尝试：
public class demo extends RemoteWebDriver {
public static WebDriver driver;
public Selenium selenium;
public WebDriverWait wait;
public String propertyFile;
String getSessionId;
public demo() { // constructor
DesiredCapabilities ieCapabilities = DesiredCapabilities
.internetExplorer();
ieCapabilities
.setCapability(
InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,
true);
driver = new InternetExplorerDriver(ieCapabilities);
this.saveSessionIdToSomeStorage(getSessionId);
this.startSession(ieCapabilities);
driver.manage().window().maximize();
}
@Override
protected void startSession(Capabilities desiredCapabilities) {
String sid = getPreviousSessionIdFromSomeStorage();
if (sid != null) {
setSessionId(sid);
try {
getCurrentUrl();
} catch (WebDriverException e) {
// session is not valid
sid = null;
}
}
if (sid == null) {
super.startSession(desiredCapabilities);
saveSessionIdToSomeStorage(getSessionId().toString());
}
}
private void saveSessionIdToSomeStorage(String session) {
session=((RemoteWebDriver) driver).getSessionId().toString();
}
private String getPreviousSessionIdFromSomeStorage() {
return getSessionId;
}
}
我希望通过重写remoteWebdriver中的startSession（）方法，它会以某种方式检查我是否已经在中打开了webdriver浏览器的一个实例，并且它将使用该实例，而不是每次我在eclipse中点击“运行”按钮时都重新创建一个新实例
我还可以看到，因为我正在从构造函数创建一个“新的驱动程序实例”，因为构造函数总是先执行，它会自动创建新的驱动程序实例，所以我可能需要以某种方式更改它，但不知道如何更改。
public class demo extends RemoteWebDriver {
public static WebDriver driver;
public Selenium selenium;
public WebDriverWait wait;
public String propertyFile;
String getSessionId;
public demo() { // constructor
DesiredCapabilities ieCapabilities = DesiredCapabilities
.internetExplorer();
ieCapabilities
.setCapability(
InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,
true);
driver = new InternetExplorerDriver(ieCapabilities);
this.saveSessionIdToSomeStorage(getSessionId);
this.startSession(ieCapabilities);
driver.manage().window().maximize();
}
@Override
protected void startSession(Capabilities desiredCapabilities) {
String sid = getPreviousSessionIdFromSomeStorage();
if (sid != null) {
setSessionId(sid);
try {
getCurrentUrl();
} catch (WebDriverException e) {
// session is not valid
sid = null;
}
}
if (sid == null) {
super.startSession(desiredCapabilities);
saveSessionIdToSomeStorage(getSessionId().toString());
}
}
private void saveSessionIdToSomeStorage(String session) {
session=((RemoteWebDriver) driver).getSessionId().toString();
}
private String getPreviousSessionIdFromSomeStorage() {
return getSessionId;
}
}
谢谢 要回答您的问题： 不可以。您不能使用当前正在计算机上运行的浏览器。但是，您可以对不同的测试使用相同的浏览器，只要它处于相同的执行状态
然而，听起来你真正的问题是一遍又一遍地运行100个测试。我建议使用测试框架（如TestNG或JUnit）。通过这些，您可以指定要运行的测试（TestNG将生成所有失败测试的XML文件，因此，当您运行它时，它将只执行失败的测试）。要回答您的问题： 不可以。您不能使用当前正在计算机上运行的浏览器。但是，您可以对不同的测试使用相同的浏览器，只要它处于相同的执行状态

var browser = wd.remote('http://localhost:4444/wd/hub');
browser.attach('df606fdd-f4b7-4651-aaba-fe37a39c86e3', function(err, capabilities) {
// The 'capabilities' object as returned by sessionCapabilities
if (err) { /* that session doesn't exist */ }
else {
browser.elementByCss("button.groovy-button", function(err, el) {
...
});
}
});
...
browser.detach();
driver.getSessionId();
要在JAVA或C#中执行同样的操作，您必须重写selenium的execute方法来捕获sessionId并将其保存在本地文件中，然后再次读取它以附加到现有的selenium会话中实际上，您可以再次使用相同的会话
var browser = wd.remote('http://localhost:4444/wd/hub');
browser.attach('df606fdd-f4b7-4651-aaba-fe37a39c86e3', function(err, capabilities) {
// The 'capabilities' object as returned by sessionCapabilities
if (err) { /* that session doesn't exist */ }
else {
browser.elementByCss("button.groovy-button", function(err, el) {

}
});

browser.detach();

driver.getSessionId();

Mohit Baluja我尝试了以下步骤来使用相同的浏览器实例，它对我有效： 如果您在不同的包中使用泛型或类1，那么下面的代码段将起作用-
