考虑使用Fluent API

Martin Fowler创造了术语 “Fluent API”. Selenium已经在其 FluentWait 类中实现了类似的东西, 这是对标准 Wait 类的替代. 您可以在页面对象中启用Fluent API设计模式, 然后使用如下代码段查询Google搜索页面:

driver.get( "http://www.google.com/webhp?hl=en&tab=ww" );
GoogleSearchPage gsp = new GoogleSearchPage(driver);
gsp.setSearchString().clickSearchButton();

Google页面对象类具有这种流畅行为后可能看起来像这样:

public abstract class BasePage {
    protected WebDriver driver;

    public BasePage(WebDriver driver) {
        this.driver = driver;
    }
}

public class GoogleSearchPage extends BasePage {
    public GoogleSearchPage(WebDriver driver) {
        super(driver);
        // Generally do not assert within pages or components.
        // Effectively throws an exception if the lambda condition is not met.
        new WebDriverWait(driver, Duration.ofSeconds(3)).until(d -> d.findElement(By.id("logo")));
    }

    public GoogleSearchPage setSearchString(String sstr) {
        driver.findElement(By.id("gbqfq")).sendKeys(sstr);
        return this;
    }

    public void clickSearchButton() {
        driver.findElement(By.id("gbqfb")).click();
    }
}
