在使用Selenium进行测试时,如何在Chrome和Firefox中调整窗口大小?

我们为Chrome,Firefox和Safari创建了扩展程序,我们希望使用Selenium测试扩展程序。我们有一个Ubuntu服务器,我在其中安装了Firefox和Chrome(使用ChromeDriver)。测试工作正常,但问题是Chrome窗口太小,并且由于窗口的大小,Chrome中的许多测试都失败了。使用Firefox,窗口很好,测试不会失败。如何使窗口尺寸更大?我们希望窗口大小为1920x1080。这是我们的代码:

run_daily_selenium_tests.sh

#!/bin/bash

cd /home/ubuntu/selenium_tests

sudo Xvfb :99 -ac -screen 0 1920x1080x24 >/dev/null 2>&1 &
export DISPLAY=:99

today_date_hour=`TZ='Asia/Tel_Aviv' date +"%Y-%m-%d_%H"`
start_hour=`TZ='Asia/Tel_Aviv' date +"%H"`
selenium_test_prefix="/home/ubuntu/selenium_tests/tests/"
selenium_test_suffix=".py"
log_prefix="/home/ubuntu/logs/selenium_tests/"

run_selenium_test()
{
    selenium_test_file_name="${selenium_test_prefix}${file_name}${selenium_test_suffix}"
    log_suffix="_${file_name}.log"
    log_file_name="${log_prefix}${today_date_hour}${log_suffix}"
    python "$selenium_test_file_name" >"$log_file_name" 2>&1
    cat "$log_file_name" | mail -s "$test_name - `TZ='Asia/Tel_Aviv' date +"%Y-%m-%d %H:%M:%S"`" <my_email_address>
}

file_name="chrome_inbox_without_extension_test"
test_name="Chrome Inbox Without Extension Test"
run_selenium_test

file_name="chrome_inbox_1_with_extension_test"
test_name="Chrome Inbox 1 With Extension Test"
run_selenium_test

.....

sudo killall Xvfb >/dev/null 2>&1

if [ $start_hour = "08" ]; then
    cd /home/ubuntu
    /home/ubuntu/scripts/send_daily_report_html.sh
fi

Selenium测试代码

def get_default_caps(self):
    caps = {}
    caps['name'] = 'Base Selenium Test'
    caps['build'] = '1.0.1'
    if (self.browser == "chrome"):
        self.browser_version = '41.0.2272.118'
        caps['browser'] = 'Chrome'
    elif (self.browser == "firefox"):
        self.browser_version = '37.0.1'
        caps['browser'] = 'Firefox'
    elif (self.browser == "safari"):
        caps['browser'] = 'Safari'
        caps['os'] = 'OS X'
        self.browser_version = "{}.0".format(randint(7, 8))
        if (self.browser_version == "7.0"):
            caps['os_version'] = 'Mavericks'
        elif (self.browser_version == "8.0"):
            caps['os_version'] = 'Yosemite'
    caps['browser_version'] = self.browser_version
    caps['resolution'] = '1920x1080'
    caps['browserstack.debug'] = 'true'
    return caps

def start_selenium_webdriver(self, caps, chrome_options=None, firefox_profile=None):
    print("Starting test \"{}\" with {} {}, resolution {}.".format(caps['name'], caps['browser'], caps['browser_version'], caps['resolution']))
    if (self.browser == "chrome"):
        self.driver = webdriver.Chrome(chrome_options=chrome_options)
    elif (self.browser == "firefox"):
        self.driver = webdriver.Firefox(firefox_profile=firefox_profile)
    else:
        self.driver = webdriver.Remote(
            command_executor='http://username:password@hub.browserstack.com:80/wd/hub',
            desired_capabilities=caps
        )
    self.driver.implicitly_wait(time_to_wait=5)
    self.driver.maximize_window()

Firefox窗口:Firefox window Chrome窗口:Chrome window

解决方案

我删除了self.driver.maximize_window(),而是添加了以下行:

    self.driver.set_window_size(1920, 1080)
    size = self.driver.get_window_size()
    print("Window size: width = {}px, height = {}px.".format(size["width"], size["height"]))

结果

使用Chrome:Window size: width = 1919px, height = 1079px.

使用Firefox:Window size: width = 1920px, height = 1080px.

测试现在通过了。

答案 0 :(得分:15)

对于Chromejust添加之前&#34; webdriver.Chrome&#34; INIT:

chrome_options.add_argument("--window-size=1920x1080")

适用于所有浏览器:

有一个官方的selenium python绑定: http://selenium.googlecode.com/git/docs/api/py/webdriver_remote/selenium.webdriver.remote.webdriver.html#selenium.webdriver.remote.webdriver.WebDriver.set_window_size

driver.set_window_size(1920, 1080)

driver.maximize_window()

或使用javascript

driver.execute_script("window.resizeTo(1920,1080)")

答案 1 :(得分:0)

driver.set_window_size(width, height)
