一、前置说明
在自动化测试中,经常需要验证多台设备的兼容性,Appium可以用同一套测试运例并行测试多个设备,以达到验证兼容性的目的。
解决思路:
- 查找已连接的所有设备;
- 为每台设备启动相应的Appium Server;
- 使用多线程执行 pytest 命令;
二、核心代码
python
# test_multi_devices.py
import pytest
from driver.appium.manager import port_manager
@pytest.fixture(scope="session")
def devicename(request):
return request.config.getoption("--devicename")
@pytest.fixture
def driver(devicename):
from driver.appium.driver import WebDriver
server_port = port_manager.get_server_port(devicename)
trans_port = port_manager.get_trans_port(devicename)
# appium 多设备并行注意事项:
# 1. server_port: 必须传值,它是 appium server 的监听端口号,在启动多个 appium server的情况下,用于指定当前driver与哪个 server 进行通信;
# 2. uuid: 必须传值,它是每个设备的唯一标识,用于appium server区分与哪台设备在通信,确保测试执行不会混淆;
# 3. systemPort: 必须传值,是UiAutomator2 Server的6790端口绑定至本地的端口号,该端口用于在本地监听并接收从 UiAutomator2 Server 发出的请求;
appium_server_url = f'http://localhost:{server_port}'
capabilities = {
"platformName": "Android",
"automationName": "uiautomator2",
"deviceName": devicename,
"udid": devicename,
"app": "D:\\resources\\ApiDemos-debug.apk",
"systemPort": trans_port
}
driver = WebDriver(command_executor=appium_server_url, capabilities=capabilities)
yield driver
driver.quit()
def test_runner(driver):
driver.smart_find_element(by='text', value='App').click()
driver.smart_find_element(by='text', value='Notification').click()
driver.smart_find_element(by='text', value='NotifyWithText').click()
driver.smart_find_element(by='text', value='SHOW SHORT NOTIFICATION').click()
element = driver.get_toast('Short notification')
assert element.text == 'Short notification'
python
# main.py
import threading
import pytest
from driver.appium.manager import MobileDevicesManager, AppiumServersManager, device_manager
from driver.appium.manager import port_manager
PY_RUNNER = 'tests/test_multi_devices.py'
def start_server_and_run_pytest(devicename):
"""
启动Appium Server,并且执行pytest
"""
port = port_manager.get_server_port(devicename)
# 为每台设备启动一个appium server
server_manager = AppiumServersManager(port)
server_manager.start_server()
# 执行pytest
pytest.main([PY_RUNNER, '-s', '-v', '--devicename', devicename])
def run_multi_devices():
"""
多设备并行测试
"""
devices = device_manager.get_connected_devices()
threads = []
for devicename in devices:
thread = threading.Thread(target=start_server_and_run_pytest, args=(devicename,))
threads.append(thread)
# 启动线程
thread.start()
# 等待所有线程完成
for thread in threads:
thread.join()
if __name__ == '__main__':
import logging.config
logging.config.fileConfig('conf/logging.conf')
# 执行并发测试
run_multi_devices()
三、Demo验证
当前有3台设备连接,执行代码,会启动3个appium server:
3台设备会同时执行测试(有1台为手机,不方便截图):
四、appium 多设备并行注意事项
python
# 1. server_port: 必须传值,它是 appium server 的监听端口号,在启动多个 appium server的情况下,用于指定当前driver与哪个 server 进行通信;
# 2. uuid: 必须传值,它是每个设备的唯一标识,用于appium server区分与哪台设备在通信,确保测试执行不会混淆;
# 3. systemPort: 必须传值,是UiAutomator2 Server的6790端口绑定至本地的端口号,该端口用于在本地监听并接收从 UiAutomator2 Server 发出的请求;
appium_server_url = f'http://localhost:{server_port}'
capabilities = {
"platformName": "Android",
"automationName": "uiautomator2",
"deviceName": devicename,
"udid": devicename,
"app": "D:\\resources\\ApiDemos-debug.apk",
"systemPort": trans_port
}
driver = WebDriver(command_executor=appium_server_url, capabilities=capabilities)
