宁静BDD / Selenium测试工作- 10项中的6项

Question

有时测试用例通过，有时由于错误而失败。

Caused by: net.thucydides.core.webdriver.DriverConfigurationError: Could not instantiate new WebDriver instance of type class org.openqa.selenium.chrome.ChromeDriver (unknown error: DevToolsActivePort file doesn't exist
  (Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Windows NT 6.1.7601 SP1 x86_64) (WARNING: The server did not provide any stacktrace information)

我用的是硒的宁静BDD。

    <serenity.version>2.0.54</serenity.version>
    <serenity.maven.version>2.0.54</serenity.maven.version>
    <serenity.cucumber.version>1.0.14</serenity.cucumber.version>
    <cucumber.version>4.2.0</cucumber.version>

当它失败时，我可以看到任务管理器中的chromeDrive.exe和chrome.exe一直在运行。

我是不是做错了什么或者硒测试用例是脆弱的？

运行程序代码

@RunWith(CucumberWithSerenity.class)
@CucumberOptions(
        plugin = {"pretty"},
        features = "src/test/resources/features",
        glue = {"starter"},
        tags = {"not @avoid"}
)
public class CucumberTestSuite {

}

serenity.conf

chrome.switches="""--start-maximized;--test-type;--no-sandbox;--ignore-certificate-errors;
                   --disable-popup-blocking;--disable-default-apps;--disable-extensions-file-access-check;
                   --incognito;--disable-infobars,--disable-gpu"""

Answer 1

更改此铬设置:转到

`chrome://settings/ ->
 Advanced ->
 Continue running background apps when Google Chrome is closed`

关闭该选项，重新启动并运行测试。

Answer 2

在serenity.conf中使用这一行

serenity.restart.browser.frequency

我认为默认情况下设置为false

Answer 3

这就是对我起作用的东西

serenity.restart.browser.for.each=NEVER

将其添加到serenity.properties文件中。
