如何解决设置 Nightwatch 的问题
我有一个 Django 项目，我正在尝试设置 nightwatch JS，但我似乎无法解决 selinum 驱动程序的问题。
我有一个这样的 node_modules 目录（显示重要区域）
node_modules
.bin
chromedriver
geckodriver
在我的根文件夹中，我编写了一个名为 custom_test.js 的测试：
module.exports = {
'NW test on Google' : function (client) {
client
.url('http://www.google.com')
.waitForElementVisible('body',1000)
.assert.title('Google')
.assert.visible('input[type=text]')
.setValue('input[type=text]','Nightwatch JS')
.waitForElementVisible('button[name=btnG]',1000)
.click('button[name=btnG]')
.pause(1000)
.assert.containsText('ol#rso li:first-child','Nightwatch.js | Node.js powered End-to-End testing framework')
.end()
}
}
package.json 中的脚本：
"nightwatch": "./node_modules/.bin/nightwatch"
为了以防万一，这里显示了来自 chromedriver 和 geckdriver 的 devDependenices
"chromedriver": "^88.0.0",
"geckodriver": "^1.22.1",
现在nightwatch.json
{
"src_folders" : [""],"webdriver" : {
"start_process": true,"server_path": "node_modules/.bin/geckodriver","port": 9515
},"test_settings" : {
"default" : {
"desiredCapabilities": {
"browserName": "firefox"
}
}
}
}
当我运行时：npm run nightwatch custom_test.js 我简单地得到：
检索新会话时发生错误：“预期的浏览器二进制位置，但无法在默认位置找到二进制文件，未提供‘moz:firefoxOptions.binary’功能，且命令行上未设置二进制标志”
>如果我将 nightwatch.json 文件更改为指向 chromedriver，我会收到此错误：
{
"src_folders" : [""],"server_path": "node_modules/.bin/chromedriver","test_settings" : {
"default" : {
"desiredCapabilities": {
"browserName": "chrome"
}
}
}
}
检索新会话时出错：“未知错误：找不到 Chrome 二进制文件”
这对我来说没有意义，因为配置只是告诉我通过 npm install 运行驱动程序的安装：
https://nightwatchjs.org/gettingstarted/configuration/
我做错了什么？
更新
将配置更改为 nightwatch.conf.js：
module.exports = {
// An array of folders (excluding subfolders) where your tests are located;
// if this is not specified,the test source must be passed as the second argument to the test runner.
src_folders: ["tests"],webdriver: {
start_process: true,port: 4444,server_path: require('chromedriver').path,cli_args: [
]
},test_settings: {
default: {
desiredCapabilities: {
browserName: 'chrome',}
}
}
}
提供此错误：
检索新会话时出错：“未知错误：找不到 Chrome 二进制文件”
这里是整个输出：
npm run nightwatch custom_test.js
> exactestate@1.0.0 nightwatch /opt/project
> nightwatch "custom_test.js"

解决方法
在您的根目录中创建一个文件 nightwatch.conf.js 并复制以下内容 -
module.exports = {
// An array of folders (excluding subfolders) where your tests are located;
// if this is not specified,the test source must be passed as the second argument to the test runner.
src_folders: [],webdriver: {
start_process: true,port: 4444,server_path: require('chromedriver').path,cli_args: []
},test_settings: {
default: {
desiredCapabilities: {
browserName: "chrome",chromeOptions: {
args: ['disable-gpu','no-sandbox','headless']
}
}
}
}
}
