Как исправить исключение в потоке "main" org.openqa.selenium.WebDriverException?

Question

Я использовал версию java8, и я протестировал первый сценарий селена с Firefox, но получаю следующее исключение.

Exception in thread "main" org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:20099 Build info: version: '3.141.0', revision: '2ecb7d9a', time: '2018-10-31T20:22:52' System info: host: 'TEST', ip: '', os.name: 'Windows 8.1', os.arch: 'amd64', os.version: '6.3', java.version: '1.8.0_211' Driver info: driver.version: FirefoxDriver at org.openqa.selenium.remote.service.DriverCommandExecutor.execute(DriverCommandExecutor.java:92) at org.openqa.selenium.remote.RemoteWebDriver.execute(RemoteWebDriver.java:552) at org.openqa.selenium.remote.RemoteWebDriver.startSession(RemoteWebDriver.java:213) at org.openqa.selenium.remote.RemoteWebDriver.<init>(RemoteWebDriver.java:131) at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:147) at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:125) at test.FistSeleniumTest.main(FistSeleniumTest.java:17) Caused by: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:20099 at okhttp3.internal.connection.RealConnection.connectSocket(RealConnection.java:247) at okhttp3.internal.connection.RealConnection.connect(RealConnection.java:165) at okhttp3.internal.connection.StreamAllocation.findConnection(StreamAllocation.java:257) at okhttp3.internal.connection.StreamAllocation.findHealthyConnection(StreamAllocation.java:135) at okhttp3.internal.connection.StreamAllocation.newStream(StreamAllocation.java:114) at okhttp3.internal.connection.ConnectInterceptor.intercept(ConnectInterceptor.java:42) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:121) at okhttp3.internal.cache.CacheInterceptor.intercept(CacheInterceptor.java:93) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:121) at okhttp3.internal.http.BridgeInterceptor.intercept(BridgeInterceptor.java:93) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) at okhttp3.internal.http.RetryAndFollowUpInterceptor.intercept(RetryAndFollowUpInterceptor.java:126) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:121) at okhttp3.RealCall.getResponseWithInterceptorChain(RealCall.java:200) at okhttp3.RealCall.execute(RealCall.java:77) at org.openqa.selenium.remote.internal.OkHttpClient.execute(OkHttpClient.java:103) at org.openqa.selenium.remote.ProtocolHandshake.createSession(ProtocolHandshake.java:102) at org.openqa.selenium.remote.ProtocolHandshake.createSession(ProtocolHandshake.java:74) at org.openqa.selenium.remote.HttpCommandExecutor.execute(HttpCommandExecutor.java:136) at org.openqa.selenium.remote.service.DriverCommandExecutor.execute(DriverCommandExecutor.java:83) ... 6 more Caused by: java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:85) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at okhttp3.internal.platform.Platform.connectSocket(Platform.java:129) at okhttp3.internal.connection.RealConnection.connectSocket(RealConnection.java:245)

Answer 1

Можете ли вы проверить, что gecko driver.exe находится на вашем компьютере, и путь указан до создания объекта драйвера.

System.setProperty("webdriver.gecko.driver", "path of the gecko driver exe");
WebDriver driver = new FirefoxDriver();

Если все работает нормально, вы можете показать мне код длявыше.
