我正在尝试在浏览器上运行 WebDriverJS，但文档对如何让它控制主机浏览器有些含糊。在这里，它说:
Launching a browser to run a WebDriver test against another browser is a tad redundant (compared to simply using node). Instead, using WebDriverJS in the browser is intended for automating the browser actually running the script. This can be accomplished as long as the > URL for the server and session ID for the browser are known. While these values may be passed to the builder directly, they may also be defined using the wdurl and wdsid "environment variables", which are parsed from the loading page's URL query data:
<!-- Assuming HTML URL is /test.html?wdurl=http://localhost:4444/wd/hub&wdsid=foo1234 -->
<!DOCTYPE html>
<script src="webdriver.js"></script>
<input id="input" type="text"/>
<script>
// Attaches to the server and session controlling this browser.
var driver = new webdriver.Builder().build();
var input = driver.findElement(webdriver.By.tagName('input'));
input.sendKeys('foo bar baz').then(function() {
assertEquals('foo bar baz',
document.getElementById('input').value);
});
</script>
我想从 Node.js 打开我的测试页面，然后运行客户端脚本中包含的命令。但是，我不知道如何在构建 session 时提取 session ID(wdsid 查询参数)。有人知道吗？
最佳答案
经过大量实验和阅读 WebDriverJS 源代码后终于弄明白了。
var webdriver = require('./assets/webdriver');
var driver = new webdriver.Builder().
usingServer('http://localhost:4444/wd/hub').
withCapabilities({
'browserName': 'chrome',
'version': '',
'platform': 'ANY',
'javascriptEnabled': true
}).
build();
var testUrl = 'http://localhost:3000/test',
hubUrl = 'http://localhost:4444/wd/hub',
sessionId;
driver.session_.then(function(sessionData) {
sessionId = sessionData.id;
driver.get(testUrl + '?wdurl=' + hubUrl + '&wdsid=' + sessionId);
});
driver.session_ 返回一个 Promise 对象，该对象在实例化时将包含 session 数据和其他信息。使用 .then(callback(sessionData)) 将允许您根据需要操作数据。
