Question

我已按照http://nightwatchjs.org/gettingstarted的步骤进行操作。在我的测试文件中，我有http://nightwatchjs.org/guide/

的下一个代码

module.exports = {
    'Demo test Google' : function (browser) {
    browser
        .url('http://www.google.com')
        .waitForElementVisible('body', 1000)
        .setValue('input[type=text]', 'nightwatch')
        .waitForElementVisible('button[name=btnG]', 1000)
        .click('button[name=btnG]')
        .pause(1000)
        .assert.containsText('#main', 'Night Watch')
        .end();
        }
};

另外，这就是我的package.json的样子。

{
  "name": "try_nw",
  "version": "1.0.0",
  "description": "try_nightwatch",
  "main": "nightwatch.js",
  "scripts": {
  "test": "node nightwatch -e chrome"
},
  "author": "",
  "license": "ISC",
"dependencies": {
  "bower": "^1.8.2",
  "chromedriver": "^2.34.0",
  "geckodriver": "^1.10.0",
  "nightwatch": "^0.9.19",
  "selenium-server-standalone-jar": "^3.8.1"
  }
}

和我的nightwatch.json

{
  "src_folders" : ["tests"],
  "output_folder" : "reports",
  "custom_commands_path" : "",
  "custom_assertions_path" : "",
  "page_objects_path" : "",
  "globals_path" : "",

    "selenium" : {
  "start_process" : true,
"start_session" : true,
"server_path" : "bin/selenium-server-standalone-3.8.1.jar",
"log_path" : "",
"port" : 4444,
"cli_args" : {
  "webdriver.chrome.driver" : "bin/chromedriver.exe",
  "webdriver.gecko.driver" : "",
  "webdriver.edge.driver" : ""
 }
},

"test_settings" : {
"default" : {
  "launch_url" : "http://localhost",
  "selenium_port"  : 4444,
  "selenium_host"  : "localhost",
  "silent": true,
  "screenshots" : {
    "enabled" : false,
    "path" : ""
  },
  "desiredCapabilities": {
    "browserName": "chrome",
    "javascriptEnabled": true,
    "acceptSslCerts": true,
    "chromeOptions" : {
      "args" : ["--no-sandbox", "--start-maximized", "--disable-infobars"]
  }
  }
},

"chrome" : {
  "desiredCapabilities": {
    "browserName": "chrome",
    "javascriptEnabled": true,
    "acceptSslCerts": true
  }
},

"edge" : {
  "desiredCapabilities": {
    "browserName": "MicrosoftEdge"
   }
  }
 }
}

但是，当我运行测试时，Chrome的空白标签会打开，控制台会显示下一个输出。

Starting selenium server... started - PID:  15024

所以，＆lt; .waitForElementVisible＆gt; 未定义。任何人都可以提出决定吗？

Answer 1

还有其他原因导致您的测试失败。我能够以相同的Warning: exif_read_data(encoded_gs_file:YXBwX2RlZmF1bHRfYnVja2V0L0dPUFIwNTMxLkpQRw==): Error reading from file: got=x3FFA(=16378) != itemlen-2=xF2A8(=62120) in D:\project\upload.php on line 17 Warning: exif_read_data(encoded_gs_file:YXBwX2RlZmF1bHRfYnVja2V0L0dPUFIwNTMxLkpQRw==): Invalid JPEG file in D:\project\upload.php on line 17超时运行您的测试，并且稍微修改就通过了。您可能想尝试增加1000 ms的超时。以下测试通过我没有问题。

waitForElementVisible()

Answer 2

您遇到的问题不是waitForElement，也不是每个sae脚本的其他任何内容。之前的setValue与chromeDriver和您的浏览器的工作方式不同。这就是为什么你看到一个标签打开，以及为什么错误信息是关于找不到body元素。

如果您更新了chromedriver，您应该可以让脚本正常工作。

.waitForElementVisible是Nightwatch模板项目中未解析的函数
