看 STF 的 Changelog 里有一条

Fixed ZUK Z1, Z2 and others by adding an alternate install location for our binaries, since /data/local/tmp is mounted as noexec on those devices. Thanks @dkw72n!

不过还在 HEAD 里没有发布，楼主可以拉取最新代码本地编译运行 STF 试试

我前段时间也在做 Selenium 自动化测试，对于这类问题的解决方法是使用 WebDriverWait。常用下面几种：

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as ec

# sec为等待时间
try:
    WebDriverWait(browser, sec).until(
        # 等待XPATH元素可见
        ec.visibility_of_element_located((By.XPATH, xpath))
        # 等待XPATH元素不可见
        ec.invisibility_of_element_located((By.XPATH, xpath))
        # 等待XPATH元素展现
        ec.presence_of_element_located((By.XPATH, xpath))
        # 等待标题为title
        ec.title_is(title)
    )
except Exception as e:
    logging.warning(e)
    sys.exit(-1)
