我正在使用 Selenium WebDriver
(Java 版本)测试基于 OpenLayers
的 API。
我想测试使用 OpenLayers
.Control.ModifyFeature 的功能。我想点击绘制的特征 (SVG),然后拖动并检查它们是否存在、可见或隐藏。
我画了一个多边形,我选择了它。见下图:
这些 SVG 元素的 HTML 在这里:
<svg id="OpenLayers_Layer_Vector_161_svgRoot" width="1235" height="495" viewBox="0 0 1235 495" style="display: block;">
<g id="OpenLayers_Layer_Vector_161_root" transform="" style="visibility: visible;">
<g id="OpenLayers_Layer_Vector_161_vroot">

</g>
<g id="OpenLayers_Layer_Vector_161_troot" />
</g>
</svg>
假设我要选择红色点。
我试过:
String xpath = "//circle[contains(@id, 'OpenLayers_Geometry_Point') AND fill = '#990000']";
List<WebElement> vertices = driver.findElements(By.xpath(xpath));
但它总是返回一个空列表[]
。
我在这里做错了什么?有谁能帮帮我吗?
非常感谢。
编辑 1 - 函数:verticesAreVisible
在单击操作之前,我想获取元素并检查它们是否可见。我正在使用这个功能。
public static boolean verticesAreVisible(WebDriver driver, String xpath) {
List<WebElement> list = driver.findElements(By.xpath(xpath));
if (list.isEmpty()) {
return false;
}
boolean visible = true;
for (int i = 0; i < list.size(); i++) {
visible = visible && list.get(i).isDisplayed();
}
return !verticesAreNotVisible(driver) && visible;
}
编辑 2 - 正确的 xPath
// This solution from Razib is valid if the SVG is on the root node
String xpath = "/*[name()='svg']/*[name()='circle']";
// I changed it so that any descendant is valid "//"
String xpath = "//*[name()='svg']//*[name()='circle']";
// Since I wanted only the red vertices, I added this
String xpath = "//*[name()='svg']//*[name()='circle' and @fill='#990000']";
最佳答案
可能您需要在 Xpath
中使用带有 name
属性的 Actions。
在您的 XPath 中使用它 -
"/*[name()='svg']/*[name()='SVG OBJECT']"
然后试试下面的代码片段——
WebElement svgObj = driver.findElement(By.xpath(XPATH));
Actions actionBuilder = new Actions(driver);
actionBuilder.click(svgObj).build().perform();
