嗨,我有这个奇怪的问题.我无法在Mac上使用chromedriver进行测试.我在这里搜索了每个可能的角落,似乎没有人帮忙.我的浏览器已启动,但它在driver.get(url)调用之前就已冻结.

我的环境:MacOS High Sierra,最新的chromedriver,截至2018年3月12日,最新的硒3.10,最新的TestNG 6.14

我的代码:

public class Temp {

@Test()
public void test1() {
    System.setProperty("webdriver.chrome.driver", "src/test/resources/chromedriver");
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--test-type");
    options.addArguments("ignore-certificate-errors");
    WebDriver driver = new ChromeDriver(options);
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.manage().window().maximize();

    driver.get("https://www.google.co.in/");
    driver.quit();
}
}

我得到的例外是:

在我们重载构造函数时,Oracle引用并未说明此关键字的最佳实践.任何人都可以建议最好的做法吗？

选项1:委托给另一个构造函数

public class A {
    private int x, y, z, p;  

    public A() {
        this(1,1,1,1);
    }

    public A(int x, int y, int z, int p) {
        this.x = x;
        this.y = y;
        this.z = z;
        this.p = p;
    }
}

和

选项2:设置每个字段而不是委托

public class A {
    private int x, y, z, p;  

    public A() {
        this.x = 1;
        this.y = 1;
        this.z = 1;
        this.p = 1;
    }

    public A(int x, int y, int z, int p) …
