界面上有些元素是要先等它出現，再等它消失，譬如loading icon
這個是等多個loading icon出現后消失
/**
* Wait for loading icon disappear in dialog and Widgets
* @author jz
*/
public void waitForLoadingIconDisappearInDialog(WebDriver driver) {
System.out.println("Wait for loading icons display in dialog or widgets.");
Function<WebDriver, Boolean> waitFn = new Function<WebDriver, Boolean>() {
@Override
public Boolean apply(WebDriver driver) {
try {
for (WebElement el : driver.findElements(By.cssSelector("div.win-bd-mask[style*='display: block'] div.win-bd-mask-waiting"))) {
if (el.isDisplayed()) {
System.out.println("Loading icon display in dialog or widgets.");
return false;
}
}
}
catch (Exception ex) {
return true;
}
return true;
}
};
WebDriverWait wait = new WebDriverWait(driver, 120, 1000);
wait.withMessage("Loading icons should disppear in dialog or widgets in 120s");
wait.until(waitFn);
System.out.println("Loading icons disspear in dialog or widgets.");
}
?這個是等一個loading icon 出現后消失
public void waitForLoadingIconDisappearInNewWebPage(WebDriver driver) {
System.out.println("Wait for loading icon display in new web page.");
final By cssSelector=By.cssSelector("div.x-mask-msg");
Function<WebDriver, Boolean> waitFn = new Function<WebDriver, Boolean>() {
public Boolean apply(WebDriver driver) {
try{
if(driver.findElement(cssSelector).isDisplayed()){
System.out.println("Loading icon display in new web page.");
return false;
}
}
catch(Exception e){
return true;
}
return true;
}
};
WebDriverWait wait = new WebDriverWait(driver, 120, 2000);
wait.withMessage("Loading icon should disappear in new web page in 120s");
wait.until(waitFn);
System.out.println("Loading icon disappear in new web page.");
}
?如果等顯現的元素變成隱藏，相對要簡單一些，先等它可見，再等它不可見
public void waitForLoadingIconDisappearInHomePage(WebDriver driver) {
this.waitForElementVisible(driver, By.cssSelector("div#window-waiting-box"), 20 ,"Waiting box should display in 20s");
this.waitForElementNotVisible(driver, By.cssSelector("div#window-waiting-box"), 120 ,"Waiting box should disppear in 120s");
}
