在Mac OS上使用Nightwatchjs在Chrome中启动testing:“拒绝连接! selenium服务器启动了吗?

我可以使用以下命令在Firefox中运行我的testing:

nightwatch -t tests/test4.js 

我的nightwatchjs.jsonconfiguration文件:

 { "src_folders" : ["tests"], "output_folder" : "reports", "custom_commands_path" : "", "custom_assertions_path" : "", "globals_path" : "", "selenium" : { "start_process" : true, "server_path" : "selenium-server-standalone-2.44.0.jar", "log_path" : "", "host" : "127.0.0.1", "port" : 4444, "cli_args" : { "webdriver.chrome.driver" : "drivers/chromedriver" } }, "test_settings" : { "default" : { "launch_url" : "http://localhost", "selenium_port" : 4444, "selenium_host" : "localhost", "silent": true, "screenshots" : { "enabled" : false, "path" : "" }, "desiredCapabilities": { "browserName": "firefox", "javascriptEnabled": true, "acceptSslCerts": true } }, "chrome" : { "desiredCapabilities": { "browserName": "chrome", "javascriptEnabled": true, "acceptSslCerts": true } } } } 

不过,我无法使用Chrome运行testing。 这里是命令:

 nightwatch -t tests/test4.js -e chrome --verbose 

而输出:

 INFO Request: POST /wd/hub/session - data: {"desiredCapabilities":{"browserName":"chrome","javascriptEnabled":true,"acceptSslCerts":true,"platform":"ANY","name":"Test4"}} - headers: {"Content-Type":"application/json; charset=utf-8","Content-Length":127} ERROR Response 500 POST /wd/hub/session{ sessionId: null, status: 13, state: 'unhandled error', value: { message: null, localizedMessage: null, cause: null, class: 'java.util.concurrent.TimeoutException', hCode: 1023736867, screen: null }, class: 'org.openqa.selenium.remote.Response', hCode: 31447144 } 

出于某些原因,相同的主要configuration选项适用于Firefox,但不适用于Chrome。 有没有人有同样的问题?

谢谢,保罗

Paul!)尝试在chrome“desiredCapabilities”块中使用selenium CLI参数。 并指定您的chromedriver二进制文件的path。 或者你可以把它添加到selenium块

 "cli_args" : { "webdriver.chrome.driver" : "<path to chromedriver>" }

但我更喜欢使用bash脚本来运行selenium服务器

 #!/bin/bash all="false" chrome="false" firefox="false" phantom="false" for var in "$@" do if [ "$var" == "firefox" ]; then firefox="true" fi if [ "$var" == "chrome" ]; then chrome="true" fi if [ "$var" == "phantomjs" ]; then phantom="true" fi if [ "$var" == "all" ]; then all="true" firefox="true" chrome="true" phantom="true" fi done if [ "$firefox" == "true" ] && [ "$phantom" == "true" ] && [ "$chrome" == "true" ]; then all="true" fi if [ "$#" -eq 0 ]; then firefox="true" fi echo Selenium will started for chrome: "$chrome" echo Selenium will started for firefox: "$firefox" echo Selenium will started for phantomjs: "$phantom" echo Selenium will started for all browsers: "$all" if [ "$chrome" == "true" ]; then nohup java -jar lib/selenium-server-standalone-2.44.0.jar -Dwebdriver.chrome.driver="lib/chromedriver"& echo $! > sel_pid_head echo "Selenium server for Chrome and FireFox started" chrome="false" firefox="false" fi if [ "$firefox" == "true" ]; then nohup java -jar lib/selenium-server-standalone-2.44.0.jar& echo $! > sel_pid_head echo "Selenium server for FireFox started" firefox="false" fi if [ "$all" == "true" ]; then nohup java -jar lib/selenium-server-standalone-2.44.0.jar -role hub -port 4455& echo $! > sel_pid_headless echo "Selenium server for PhantomJS started" echo "Waiting 3 sec to register ghost driver into Selenium hub" sleep 3 nohup phantomjs --webdriver=8080 --webdriver-selenium-grid-hub=http://127.0.0.1:4455& echo "PhantomJS registred in Selenium Server" echo $! > ghost_pid phantom="false" all="false" fi if [ "$phantom" == "true" ] then nohup java -jar lib/selenium-server-standalone-2.44.0.jar -role hub -port 4455& echo $! > sel_pid_headless echo "Selenium server for PhantomJS started" echo "Waiting 3 sec to register ghost driver into Selenium hub" sleep 3 nohup phantomjs --webdriver=8080 --webdriver-selenium-grid-hub=http://127.0.0.1:4455& echo "PhantomJS registred in Selenium Server" echo $! > ghost_pid phantom="false" fi
