# 使用 Selenium 和 WebDriver
|
||
|
||
根據 [ChromeDriver - WebDriver for Chrome][chrome-driver]：
|
||
|
||
> WebDriver is an open source tool for automated testing of web apps across many
|
||
> browsers. It provides capabilities for navigating to web pages, user input,
|
||
> JavaScript execution, and more. ChromeDriver is a standalone server which
|
||
> implements WebDriver's wire protocol for Chromium. It is being developed by
|
||
> members of the Chromium and WebDriver teams.
|
||
|
||
為了與 Electron 一起使用 `chromedriver`，你需要告訴 `chromedriver` 去哪找 Electron 並讓他知道 Electron 是 Chrome 瀏覽器。
|
||
|
||
## 透過 WebDriverJs 設定
|
||
|
||
[WebDriverJs](https://code.google.com/p/selenium/wiki/WebDriverJs) 提供一個 Node 套件來透過 web driver 做測試，我們將使用它作為例子。
|
||
|
||
### 1. 啟動 ChromeDriver
|
||
|
||
首先你需要下載 `chromedriver` 執行檔，然後執行它：
|
||
|
||
```bash
|
||
$ ./chromedriver
|
||
Starting ChromeDriver (v2.10.291558) on port 9515
|
||
Only local connections are allowed.
|
||
```
|
||
|
||
記住埠號(port number) `9515`，等等會使用到它
|
||
|
||
### 2. 安裝 WebDriverJS
|
||
|
||
```bash
|
||
$ npm install selenium-webdriver
|
||
```
|
||
|
||
### 3. 連接到 ChromeDriver
|
||
|
||
與 Electron 一起使用 `selenium-webdriver` 的方法基本上與 upstream 相同，除了你需要手動指定如何連接 chrome driver 和去哪找 Electron 的執行檔：
|
||
|
||
```javascript
|
||
const webdriver = require('selenium-webdriver')
|
||
|
||
var driver = new webdriver.Builder()
|
||
// The "9515" is the port opened by chrome driver.
|
||
.usingServer('http://localhost:9515')
|
||
.withCapabilities({
|
||
chromeOptions: {
|
||
// Here is the path to your Electron binary.
|
||
binary: '/Path-to-Your-App.app/Contents/MacOS/Atom'
|
||
}
|
||
})
|
||
.forBrowser('electron')
|
||
.build()
|
||
|
||
driver.get('http://www.google.com')
|
||
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver')
|
||
driver.findElement(webdriver.By.name('btnG')).click()
|
||
driver.wait(function () {
|
||
return driver.getTitle().then(function (title) {
|
||
return title === 'webdriver - Google Search'
|
||
})
|
||
}, 1000)
|
||
|
||
driver.quit()
|
||
```
|
||
|
||
## 透過 WebdriverIO 設定
|
||
|
||
[WebdriverIO](http://webdriver.io/) 提供一個 Node 套件來透過 web driver 做測試。
|
||
|
||
### 1. 啟動 ChromeDriver
|
||
|
||
首先你需要下載 `chromedriver` 執行檔，然後執行它：
|
||
|
||
```bash
|
||
$ chromedriver --url-base=wd/hub --port=9515
|
||
Starting ChromeDriver (v2.10.291558) on port 9515
|
||
Only local connections are allowed.
|
||
```
|
||
|
||
記住埠號(port number) `9515`，等等會用到它
|
||
|
||
### 2. 安裝 WebdriverIO
|
||
|
||
```bash
|
||
$ npm install webdriverio
|
||
```
|
||
|
||
### 3. 連接到 chrome driver
|
||
|
||
```javascript
|
||
const webdriverio = require('webdriverio')
|
||
var options = {
|
||
host: 'localhost', // Use localhost as chrome driver server
|
||
port: 9515, // "9515" is the port opened by chrome driver.
|
||
desiredCapabilities: {
|
||
browserName: 'chrome',
|
||
chromeOptions: {
|
||
binary: '/Path-to-Your-App/electron', // Path to your Electron binary.
|
||
args: [/* cli arguments */] // Optional, perhaps 'app=' + /path/to/your/app/
|
||
}
|
||
}
|
||
}
|
||
|
||
var client = webdriverio.remote(options)
|
||
|
||
client
|
||
.init()
|
||
.url('http://google.com')
|
||
.setValue('#q', 'webdriverio')
|
||
.click('#btnG')
|
||
.getTitle().then(function (title) {
|
||
console.log('Title was: ' + title)
|
||
})
|
||
.end()
|
||
```
|
||
|
||
## 運作流程
|
||
|
||
要在不重新建置 Electron 的情況下測試你的應用程式，只需要 [放置](https://github.com/electron/electron/blob/master/docs/tutorial/application-distribution.md) 你的應用程式到 Electron 的資源目錄中即可。
|
||
|
||
或者，傳遞一個指向你應用程式資料夾的參數來透過你的 Electron 執行檔運行，這會減少複製你應用程式到 Electron 資源資料夾的需求。
