selenium-webdriver - 在 Firefox 或 IE 中使用 Protractor

Question

Protractor 在 Chrome 上运行良好，但我无法让它启动 Firefox 或 Internet Explorer。

视窗 7

节点 v6.9.1

摘自 package.json :

"scripts": {
    ....
    "webdriver-manager-update": "webdriver-manager update --ie",
    "protractor": "protractor protractor.conf.js",
    ...
},
...
"devDependencies": {
    ...
    "protractor": "5.1.1",
    ...
}

protractor.conf.js :

exports.config = {
    capabilities: {
      browserName: "firefox" // or "internet explorer"
    },
    specs: ["target/e2e/**/*.e2e-spec.js"]
};

运行后 npm run webdriver-manager-update , <project-home>\node_modules\protractor\node_modules\webdriver-manager\selenium\包含文件 chromedriver_2.28.exe , geckodriver-v0.15.0.exe和 IEDriverServer3.3.0.exe .

运行时 npm run protractor ，我收到一个错误:

[12:29:45] I/launcher - Running 1 instances of WebDriver
[12:29:45] I/local - Starting selenium standalone server...
[12:29:46] I/local - Selenium standalone server started at http://192.168.213.25:62661/wd/hub
[12:29:46] E/launcher - The path to the driver executable must be set by the webdriver.gecko.driver system property

(对于 IE，它指的是 webdriver.ie.driver 系统属性)

经过大量的谷歌搜索，我尝试了以下修复:

a) 添加 <project-home>\node_modules\protractor\node_modules\webdriver-manager\selenium\到系统环境变量 Path .这似乎没什么区别。

b) 将以下行添加到 protractor.conf.js :

seleniumArgs: ["-Dwebdriver.gecko.driver=<project-home>\\node_modules\\protractor\\node_modules\\webdriver-manager\\selenium\\geckodriver-v0.15.0.exe"],

现在 npm run protractor产量:

[12:40:35] I/launcher - Running 1 instances of WebDriver
[12:40:35] I/local - Starting selenium standalone server...
[12:40:35] E/launcher - Error: Error: Server terminated early with status 1
    at Error (native)
    at earlyTermination.catch.e (<project-home>\node_modules\selenium-webdriver\remote\index.js:252:52)
    at process._tickCallback (internal/process/next_tick.js:103:7)
[12:40:35] E/launcher - Process exited with error code 100

(与 IE 的类似行为)

我的搜索结果表明我不是唯一遇到此问题的人，但不幸的是，我没有找到解决方案。

Answer 1

最后我在 answer by Nick Tomlin 中找到了解决方案:

它不是 seleniumArgs您需要设置，但是localSeleniumStandaloneOpts.jvmArgs .所以，在 protractor.conf.js ， 写:

localSeleniumStandaloneOpts: {
    jvmArgs: ["-Dwebdriver.gecko.driver=<project-home>\\node_modules\\protractor\\node_modules\\webdriver-manager\\selenium\\geckodriver-v0.15.0.exe"]
  },

(类似于 IE)
