I'm creating a list of IWebElements to access each of elements from same type, but the test works slowly when I want to access a certain element. I came with the idea to create a dictionary of elements and access each element by it's name (text that is stored in this element). I found some topics here but was unable to make them work for me. This is the way I'm accessing elements.
public IWebElement OneElement
{
get
{
return this.Driver.FindElement(By.Id("oneElement"));
}
}
public List<IWebElement> ListOfNames
{
get
{
return this.Driver.FindElements(By.Id("name")).ToList();
}
}
You can try the following code to get element by it's text and it is fast compared the list of elements as list needs to be searched till element found. it will take time if searched element is at the last position in the list. Below code will be direct fetch of particular element. Try it and let us know.
public IWebElement GetElementByText(String text)
{
get
{
return this.Driver.FindElement(By.xpath(String.Format("//*[#id='name'][text()='{0}']",text)));
}
}

So I am using a dynamic object and I can receive an API that lists all of the object's properties such as ID in one page, but that ID is the ID of a frame layout that is not interactable and only contains child such as textbox or error message.
what I'm trying to achieve is to know the properties of that parent object so that I can try to interact with the child, for example, the textbox EditText inside. I am able to interact with the child by using the XPath but haven't found a way to determine the parent by the determined ID.
I am trying to make automatic testing that only uses the API as a reference point to check what is the object to test so that in the future I don't have to change the test script in case of any changes in the configuration.
I can check the API for existing object properties like this:
public static checkIfExistForm1(String code){
def response = WS.sendRequest(findTestObject("Object Repository/WebService"))
def json = new JsonSlurper().parseText(response.getResponseBodyContent())
for(int i = 0;i < json.page.form.fieldset.size(); i++){
if(code.contentEquals(json.page.form.fieldset[i].control[0].id)){
return true;
break
}
}
return false;
}
and then I can make some kind of method to get the child of that object and try to interact with it
for example with this method I can select an object by XPath
public static getObjectID(String code){
//considering i know that this is the child, or creating another validation
//the child(EditText) also has ID "content-desc" that i can use
String dynamicIdPath = '//*[#content-desc="%s"]'
String xpath = String.format(dynamicIdPath,code)
TestObject to = new TestObject()
to.addProperty("xpath", ConditionType.EQUALS, xpath)
return to
}
any thoughts? thanks!
I am working on an Eclipse plugin which loads a URL in the SWT browser. This page rendered in the browser has hidden html attributes. The requirement is to read the values of the hidden attributes.
Browser browser = new Browser(shell, SWT.NONE);
browser.setUrl("www.<my_url>.com");
I tried to execute a query on the DOM using the statusTextListener
browser.addStatusTextListener(new StatusTextListener() {
public void changed(StatusTextEvent event) {
browser.setData("query", event.text);
}
});
browser.addProgressListener(new ProgressListener() {
public void completed(ProgressEvent event) {
boolean result = browser
.execute("window.status=document.getElementById('main').childNodes[0].nodeValue;");
if (!result) {
/* Script may fail or may not be supported on certain platforms. */
System.out.println("Script was not executed.");
return;
}
String value = (String) browser.getData("query");
System.out.println("Node value: " + value);
}
});
However this does not seem to work. It works well if I try to load HTML text in the browser instead of the URL.
Any idea how to read DOM elements from the SWT browser after the page load is complete?
Use Browser::evaluate to execute Javascript in the context of the document and return the result to the caller.
To obtain the value of the first child of the main element in your example, start like this:
String script = "<Javascript to return an array of hidden attribute names>";
Object result = browser.evaluate(script);
The supported result types, however, are limited to string, number, and boolean - and arrays of these types. Javascript that evaluates to null or undefined will return null.
Hence, you will need to adjust your Javascript that queries the DOM to return a supported type.
I have been writing selenium scripts for a while in Java. I encountered a very weird issue today. Here is the issue:
I cleared a text field using webelement.clear() method, later while executing next command (click event), the text area I had previously cleared, is now populated with previously filled value.
Here is the code snippet:
mobileNumField.get(0).clear();
Thread.sleep(4500);
emailAddress.get(0).click();
emailAddress.get(0).clear();
Thread.sleep(4500);
emailAddress.get(0).sendKeys(Keys.TAB);
I don't know the exact reason for your element keeping its value, but you can try an alternative text clearance by sending 'Ctrl+A+Delete' key combination using sendKeys method of the element's object:
emailAddress.sendKeys(Keys.chord(Keys.CONTROL,"a", Keys.DELETE));
It's possible that the fields you're trying to fill has autocomplete attribute set to on. [Reference]
If clear() works when the line executes then it's safe to say that this is not a webdriver specific issue.
It would help if you can show the html snippet of the page section you're working on.
Possible areas of debugging:
forcefully remove autocomplete attribute on page load using java script executor
turn off autocomplete setting on the driver level. I believe the solution would vary depending on the driver being used.
Good luck!
PS: Those Thread.sleep(s) are not advisable.
I solved it by adding a function to my BasePage to clear fields by a given WebElement.
public void clearWebField(WebElement element){
while(!element.getAttribute("value").equals("")){
element.sendKeys(Keys.BACK_SPACE);
}
}
You can also implement this method in the page that experiencing the problem.
I am using Mac and the following code helps also
public static void macCleanHack(WebElement element) {
String inputText = element.getAttribute("value");
if( inputText != null ) {
for(int i=0; i<inputText.length();i++) {
element.sendKeys(Keys.BACK_SPACE);
}
}
}
I had a similar issue with a text field that used an auto-complete plugin. I had to explicitly clear the attribute value as well as do a SendKeys. I created an extension method to encapsulate the behaviour, hopefully the snippet below will help:
public static void SendKeysAutocomplete(this IWebElement element, string fieldValue)
{
element.SendKeys(fieldValue);
element.SetAttribute("value", fieldValue);
}
public static void SetAttribute(this IWebElement element, string attributeName, string attributeValue)
{
var driver = WebDriverHelper.GetDriverFromScenarioContext();
var executor = (IJavaScriptExecutor)driver;
executor.ExecuteScript("arguments[0].setAttribute(arguments[1], arguments[2]);", element, attributeName, attributeValue);
}
Faced a similar problem. The input field is cleared but the error message is not updated. It seems that some input fields work correctly only if you enter and delete a character:
element.sendKeys(text);
element.sendKeys(Keys.SPACE, Keys.BACK_SPACE);
Hope this helps to clear the field and then sendKeys() the needed value
while (!inputField.getAttribute("value").equals("")) {
inputField.sendKeys(Keys.BACK_SPACE);
}
inputField.sendKeys("your_value");
In some webforms clearing the field followed by .sendKeys() won't work because it keeps repopulating it with some autofill value (in my case it was due to an onfocus attribute function of an input element). Action chains didn't help, the only thing that worked for me was replacing the value attribute directly with javascript:
In Java:
driver.executeScript("document.getElementById('elementID').value='new value'");
In Python (nearly identical):
driver.execute_script("document.getElementById('elementID').value='new value'")
For more on the Java version of this solution see this question.
As part of Selenium Web-driver learning I came across a scenario. Please let me know the professional approach to proceed.
I am testing a eCommerce application where while I click on Mobile link all mobile phones are getting displayed.I want to check whether they are sorted based on name and price. So basically I need to get Name & price of all elements in the result page.
So My Question is there any way I can map html elements to java value objects ? Any API already available for doing this mapping for me ? Something similar to gson api for converting java objects to their corresponding Json representation ?
Deepu Nair
//Get all the mobile phones links into a list before sorting
List<WebElement> mobilelinks=driver.findElements(("locator"));
Map maps = new LinkedHashMap();//use linked hash map as it preserves the insertion order
for(int i=0;i<mobilelinks.size();i++){
//store the name and price as key value pair in map
maps.put("mobilelinks.get(i).getAttribute('name')","mobilelinks.get(i).getAttribute('price')" );
}
/*sort the map based on keys(names) store it in a separate list
sort the map based on values(prices) store it in a separate list
*/
/* Using webdriver click the sort by name and compare it with the list which we got after sorting
and also click sort by prices and compare it with the list*/
To catch an assertion and continue with the test after assertion failures override the Assertion class and create your own CustomAssertion or use SoftAssertions
CustomAssertion.java
public class CustomAssertions extends Assertion {
private Map<AssertionError, IAssert> m_errors = Maps.newLinkedHashMap();
#Override
public void executeAssert(IAssert a) {
try {
a.doAssert();
} catch(AssertionError ex) {
onAssertFailure(a, ex);
System.out.println(a.getActual());
System.out.println(ex.getMessage());
m_errors.put(ex, a);
}
}
public void assertAll() {
if (! m_errors.isEmpty()) {
StringBuilder sb = new StringBuilder("The following asserts failed:\n");
boolean first = true;
for (Map.Entry<AssertionError, IAssert> ae : m_errors.entrySet()) {
if (first) {
first = false;
} else {
sb.append(", ");
}
sb.append(ae.getKey().getMessage());
}
throw new AssertionError(sb.toString());
}
}
}
Instead of using Assertions class to verify the tests use CustomAssertions class
Ex:
//create an object of CustomAssertions class
CustomAssertions custom_assert=new CustomAssertions();
cust_assert.assertTrue(2<1);
cust_assert.assertEquals("test", "testing");
//and finally after finishing the test in aftersuite method call
cust_assert.assertAll();
Hope this helps you if you have any doubts kindly get back...
Is their any way to find the object locator type, by passing the object locator alone.
for e.g. i need to click on a login button, where its id=login, classname=loginbutton or xpath=//input[#name='login']. I need to build method where i will be just passing the objectlocator (either id or name) as the input and its type(either id or name) should be decided in the method like if it contains // then type should be of xpath etc.
I need to pass the objectLocator() which returns type to the findElement()
WebElement element = driver.findElement(objectLocator());
I do not think it is available off the shelf, you would have to implement your own logic.
The only thing is, let's say you want to search by linktext. As per your usecase, you would, in your object repo specify, "this is my linktext".
Now how do you know it is an id or a name or a linktext?
For xpath you can check if it starts with /, then its an xpath. If its only id or name then you can use ByIdorName, but i think it would become tricky with css and linktext.
The one thing I can think is you can establish some sort of conventions like if it is linktext precede your lcoator definition with linktext=blah blah and then you split and consume it.
I find it very useful to store all my locators as By objects and either use the By directly or pass the By into methods as I need them. For example:
By passwordField= By.id("login");
By userNameField = By.name("username");
By submitButton = By.xpath("\\myxpath\div[2]");
public void clickLogin() {
driver.findElement(submitButton).click();
}
I also use static Bys from other classes as well:
public void clickLogin() {
driver.findElement(LoginPage.SUBMIT_BUTTON).click();
}
The modern way to do this is using PageFactory and PageObjects
The following is a quick and dirty which will adapt selenium locators strings to WebDriver locators.
public enum LocatorType {
CLASSNAME, CSS, ID, LINK, NAME, TAGNAME, XPATH ;
}
public WebElement objectLocator(LocatorType type, String ref) {
switch(type) {
case ID:
return this.webDriver.findElement(By.id(ref));
case CLASSNAME:
return this.webDriver.findElement(By.className(ref));
case XPATH:
return this.webDriver.findElement(By.xpath(ref));
case CSS:
return this.webDriver.findElement(By.cssSelector(ref));
case LINK:
return this.webDriver.findElement(By.linkText(ref));
case NAME:
return this.webDriver.findElement(By.name(ref));
case TAGNAME:
return this.webDriver.findElement(By.tagName(ref));
}
return null;
}
public WebElement objectLocator(String identifier) {
String typeString = identifier.substring(0, identifier.indexOf('='));
String ref = identifier.substring(identifier.indexOf('=')+1, identifier.length());
if (typeString.toLowerCase().contains("classname")) {
return objectLocator(LocatorType.CLASSNAME, ref);
} else if (typeString.toLowerCase().contains("css")) {
return objectLocator(LocatorType.CSS, ref);
} else if (typeString.toLowerCase().contains("id")) {
return objectLocator(LocatorType.ID, ref);
} else if (typeString.toLowerCase().contains("link")) {
return objectLocator(LocatorType.LINK, ref);
} else if (typeString.toLowerCase().contains("name")) {
return objectLocator(LocatorType.NAME, ref);
} else if (typeString.toLowerCase().contains("tagname")) {
return objectLocator(LocatorType.TAGNAME, ref);
} else if (typeString.toLowerCase().contains("xpath")) {
return objectLocator(LocatorType.XPATH, ref);
} else {
return null;
}
}
It looks like you are looking for this solution because you have an object repository maintained somewhere outside of your code in some kind of properties file or xml.
Using gui maps has lot of disadvantages like,
- maintain an external file with a list of locators
- parse locator files to read keys (you can abstract this but still an overhead)
- when writing PageObjects you need to switch back and forth from Page to gui map
- possibility of multiple duplicate locators in gui maps
- object repo grows over time and becomes impossible to maintain
- debugging is far more difficult
What you are looking for is adding one more layer of complexity which is not required in my opinion. Automating browsers is a challenge in itself and writing maintainable test automation code is utmost important.
Use PageFactory in your page objects.
- Natural place for your locators are Page Objects themselves.
- Locators easily accessible in page objects for review or correction
- No need for explicit driver.findElement, with #FindBy you get that for free
- modern Java and awesome annotations make page objects look beautiful & readable
I have used gui maps before and struggled a lot. Switching to page factory made me realize that using object repository was such a bad idea!
This should do for locating element. I have given example till 3 level deep.
public WebElement findElement(String locator){
WebElement w = null;
try{
return (driver.findElement(By.id(locator)));
}catch(Exception e1){
try{
return ( driver.findElement(By.name(locator)));
}catch(Exception e2){
try{
return (driver.findElement(By.xpath(locator)));
}catch(Exception e3){
System.out.println("Cound not find a locator");
e3.printStackTrace();
}
}
}
return(w);
}
public void type(String locator, String value){
try{
WebElement w= findElement(locator);
w.sendKeys(""+value);
Thread.sleep(sleepTime);
}catch(Exception e){
e.printStackTrace();
}
}
