我正在尝试使用一个Enum来设置一个可能的距离的有限列表,该字符串被用作Selenium API方法中的cssSelector:

public enum DistanceFrom {

    FIVEMILES("a[data-reactid='.2cr8yg16ohc.2.1.0.2:$5.0']"),
    TENMILES("a['.2cr8yg16ohc.2.1.0.2:$10.0.2']"),
    TWENTYMILES("a['.2cr8yg16ohc.2.1.0.2:$20.0']"),
    THIRTYMILES("a['.2cr8yg16ohc.2.1.0.2:$30.0']");


    private String value;

    DistanceFrom(String value){
        this.value=value;
    }

    @Override
    public String toString(){
        return value;
    }
}

我在测试中使用它:

local.setDistance(DistanceFrom.FIVEMILES.toString());

其中setDistance是页面对象中的一种流畅方法:

  public LocalNewsPage setDistance(String value) {
    WebElement setDistanceButton = driver.findElement(By.cssSelector(value));
    setDistanceButton.click();
    return this;
}

为什么我必须声明:

local.setDistance(DistanceFrom.FIVEMILES.toString());

而且不能简单地:

local.setDistance(DistanceFrom.FIVEMILES);

1 个答案:

答案 0 :(得分:0)

如果您可以编辑setDistance方法,则可以将其更改为接受DistanceFrom

public LocalNewsPage setDistance(DistanceFrom value) {
    WebElement setDistanceButton = driver.findElement(By.cssSelector(value.toString()));
    setDistanceButton.click();
    return this;
}

或者,您可以将DistanceFrom中的枚举值更改为static final String s:

public final class DistanceFrom {

    public static final String FIVEMILES = "a[data-reactid='.2cr8yg16ohc.2.1.0.2:$5.0']";
    public static final String TENMILES = "a['.2cr8yg16ohc.2.1.0.2:$10.0.2']";
    public static final String TWENTYMILES = "a['.2cr8yg16ohc.2.1.0.2:$20.0']";
    public static final String THIRTYMILES = "a['.2cr8yg16ohc.2.1.0.2:$30.0']";

    private DistanceFrom() {}
}
