我正在尝试评估 Selenium-Jupiter，但会遇到不同的问题和行为，具体取决于我使用的版本。

我正在使用 gradle 4.6 和

> docker version | grep API
API version:     1.24
API version:     1.24

当使用io.github.bonigarcia:selenium-jupiter:2.1.0时

gradle clean test --info
...
 Caused by:

gradle clean test --info

我假设 Selenium-Jupiter 和 Selenoid 之间的交互需要一些配置，例如 DOCKER_API_VERSION 如此处所述 http://aerokube.com/selenoid/latest/#_recommended_docker_settings 但我不知道从 Selenium-Jupiter 方面在哪里进行此配置。

我意识到这是一个相当模糊的呼救声，但希望至少有人能给我一些关于如何解决这个问题的提示。我真的很喜欢使用 Docker 进行这种虚拟化的想法，我认为我们的 GUI 测试确实可以从这样的解决方案中受益。

【解决方案1】：

您可以更改 Selenium-Jupiter 使用的 Docker API 的版本，如下所示：

import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.RegisterExtension;
import org.openqa.selenium.WebDriver;

import io.github.bonigarcia.seljup.SeleniumExtension;

public class MyTest {

    @RegisterExtension
    static SeleniumExtension seleniumExtension = new SeleniumExtension();

    @BeforeAll
    static void setup() {
        seleniumExtension.getConfig().setDockerApiVersion("API-version"); // 1.35 by default
    }

    @Test
    void test(WebDriver driver) {
        // your test
    }

}

在撰写本文时，我将使用最新版本的 Selenium-Jupiter 3.1.0。
