NoSuchElementError for Android Appium locators - javascript

I am using Appium 1.22.3 and webdriverIO5 for Android mobile automation
The DOM for the element I am trying to click on is as below:
<android.widget.Button content-desc="Sign in">
I have used different combinations of locators as below:
await $('android.widget.Button');
driver.elementsByAccessibilityId('Sign in');
$('Sign in');
$('id=Sign in')
findElementByAccessibilityId("Sign in");
dr.findElementByAccessibilityId("Sign in")
However none of these xpaths work and I get error as below:
2022-09-04 12:35:01:866 - [HTTP] {"using":"class name","value":"android.widget.Button"}

Appreciate any help on how to identify the correct locator here

Thanks. I was able to use let el = await $('//android.widget.Button[#content-desc="Sign in"]'); successfully finally!

Click and touch actions don't work in a React Native app Appium test via WebdriverIO

I starting to test a React Native app with Appium and Weddriver.io via the XCIUTest driver (documented here and here), initially on iOS targeting a simulator. It's early days: I've got the framework installed and running and set up an initial test - in which I want to click a T&C checkbox and then click a submit button on the initial welcome screen of my app. However neither the "click" nor the "touchAction" commands do anything - they don't trigger the onPress action callback or check the checkbox.
The component selectors are working OK, as I can query the "label" of the elements selected and they are correct (and if I purposefully break the accessibility id I get errors). I can also write to an field which I added for testing and I can change the text value to another string from the test, so I know I've got it generally set up and communicating with my app in the simulator OK.
I am targeting the BundleId of an already installed app (rather than a Zip to install which is another method).
So why might the click or touch actions not be triggering their behaviour?
Are there pitfalls around permissions, capabilities or security issues in Appium?
Should I be using "click" or "touch" in a React Native tests?
I am using React Native Base but I have replaced those UI components with simpler ones from React Native to remove that complication.
There is debug logging in the onPress callback, so if I click the button manually I see the logs, but commands from the Mocha tests don't log the attempt nor perform any actions.
Relevant package.json dependency versions:
dependencies:
"native-base": "~3.4",
"react": "17.0.2",
"react-native": "0.67.4",
dev-dependencies:
"#babel/core": "^7.17.10",
"#babel/preset-env": "^7.17.10",
"#babel/register": "^7.17.10",
"#babel/runtime": "^7.17.10",
"chai": "^4.1.2",
"mocha": "^8.0.1",
"webdriverio": "^7.20.9"
I have Appium v8.5.5 installed globally, running in a terminal.
node: v16.15.0, npm: v8.5.5
I have tried many things, like waitForDisplayed, clicking the button before and/or after the successful input field text-entry, adding a and clicking or touching that. I don't see any errors or warnings.
e.g. in my component (the checkbox and button are real, the input and link were added just for testing)
async function onClickAgree() {
console.log('HelpScreen.onClickAgree')
}
...
<Checkbox accessibilityLabel={ 'help_agree_checkbox' }
accessible={true}
isChecked={agree}
onChange={onChangeAgreeCheckbox}
value="agree"
label="Accept terms and conditions"
marginX="30"/>
<Button accessibilityLabel={ 'help_agree_submit_button' }
accessible={true}
width={300}
onPress={() => onClickAgree()}
title="Get Started"
>
Get Started
</Button>
<Link
accessibilityLabel="help_agree_test_link"
accessible={true}
onPress={onClickAgree}>
Test link
</Link>
<Input accessibilityLabel={ 'help_agree_test_input' }
accessible={true}
value={testInputContent} onChangeText={setTestInputContent} minWidth={200}></Input>
and in the test case:
import { remote } from 'webdriverio';
const opts = {
path: '/wd/hub',
port: 4723,
capabilities: {
automationName: "XCUITest",
platformName: "iOS",
deviceName: "iPad Pro (12.9-inch) (3rd generation)",
platformVersion: "13.2",
appPackage: "com.mydomain.myapp", // my app's bundleId
}
}
describe('Initial test...', function (){
let client;
beforeEach(async function () {
client = await remote(opts);
});
after(async function () {
await client.deleteSession()
})
it('should do a test', async function () {
const button = await client.$("~help_agree_submit_button")
// await button.click() // doesn't work!
await button.touchAction('tap') // doesn't work!
await client.$("~help_agree_submit_button").click()// doesn't work!
//
// TODO: why don't any of the Tap/Clicks work??
const link = await client.$("~help_agree_test_link")
await link.click() // doesn't work!
await link.touchAction('tap') // doesn't work!
//
const input = await client.$("~help_agree_test_input")
await input.setValue('QA testing injection content') // works
//
await link.click() // doesn't work!
await link.touchAction('tap') // doesn't work!
//
await input.setValue('QA2 testing injection content') // works!
//
await button.click() // doesn't work!
await button.touchAction('tap')// doesn't work!
//
const field = await client.$("~help_agree_checkbox")
// await field.waitForClickable({ timeout: 3000 }) // no such method, webdriverio docs: not supported in native!
await field.waitForDisplayed({ timeout: 3000 })
// const field = await client.$("Checkbox");
// const field = await client.$("ForwardRef(Checkbox)") // invalid but this is the name from the inspector
await field.click() // doesn't work
await field.touchAction('tap') // doesn't work...
...
The logs from the test runner show the Click and Touch commands being sent, and they seem similar to the successful POST for the input which works, so I can't see anything failing there.

It turns out the automation is clicking at the wrong co-ordinates.
I found there are additional logs you can enable to help debug.
capabilities.showIOSLog streams iOS simulator debugging output,
which goes into the Appium server logs.
logLevel:debug sets Webdriver to emit lower level logging which turns up in the Mocha test logs as additional "DEBUG" entries.
With these enabled I noticed a difference between the x,y position returned by the Appium/Webdriver Get Element Rect() or Location() commands and the iOS XCSynthesizedEventRecord activity which is triggered by the Click command.
Appium logs:
[IOSSimulatorLog] [IOS_SYSLOG_ROW] <XCSynthesizedEventRecord 'tap'>
[IOSSimulatorLog] [IOS_SYSLOG_ROW] Path 1:
[IOSSimulatorLog] [IOS_SYSLOG_ROW] Touch down at 542.5, 613.8, offset=0.00s
Mocha output:
/2E000000-0000-0000-67C7-000000000000/rect
2022-08-19T02:52:53.698Z INFO webdriver: RESULT { y: 595, x: 487, width: 111, height: 38 }
Considering where the x,y is registered "X axis position of the top-left corner of the web element " - W3C
So the button rect is [595, 487] to [706,525]
So 542.5, 613.8 would miss it.
I finally got the click to register using this minimum offset. Interestingly clicking right on the x,y doesn't trigger it.
client.touchPerform([
{ action: 'press', options: { x: rect.x+1, y: rect.y+1 }},
{ action: 'release' }
]);
Finally in my app console debug logs:
LOG HelpScreen.onClickAgree !!!!
So I still have the remaining problem of why or who is getting the coordinates wrong (e.g. XCUITest, iOS, React Native, React Native Base or my app layout), but at least I know what the problem is - and it's nothing to do with security, permissions or the test platform setup.

casperjs/slimerjs invalid selector in waitForSelector, which works in getElementByXPath?

I have this HTML file, test_xpath.htm:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
<body>
<h1>Hello World!</h1>
<div>
Click me!
</div>
</body>
</html>
In the folder of this file, I run PHP CLI > 5.4 as a server like this:
php -S localhost:8080
... so the HTML page is available at http://localhost:8080/test_xpath.htm.
Then I run this SlimerJS code:
// run with:
// SLIMERJSLAUNCHER=/usr/bin/firefox46 /home/USERNAME/.nvm/versions/node/v4.0.0/lib/node_modules/casperjs/bin/casperjs --engine=slimerjs test_xpath.js
var casper = require('casper').create({
verbose: true,
logLevel: 'debug',
userAgent: 'Mozilla/5.0 (X11; Linux i686; rv:43.0) Gecko/20100101 Firefox/43.0',
viewportSize: {width: 1024, height: 768},
pageSettings: {
loadImages: false,//The script is much faster when this field is set to false
loadPlugins: false,
}
});
casper.on("url.changed", function(){
this.then(function(){
this.echo("URL changed " + this.getCurrentUrl()); //getTitle());
});
});
casper.on('remote.message', function(message) {
this.echo('remote message caught: ' + message);
});
casper.start().thenOpen("http://localhost:8080/test_xpath.htm", function() {
console.log("website opened");
});
// set this to true to run - causes "[error] [remote] findAll(): invalid selector provided "//*[text()="Click me!"]":SyntaxError: An invalid or illegal string was specified"
if (false) {
casper.waitForSelector('//*[text()="Click me!"]', function() {
this.echo("I'm sure //*[text()='Click me!'] is available in the DOM");
});
}
casper.then(function(){
this.evaluate(function(){
var aelem = __utils__.getElementByXPath('//*[text()="Click me!"]');
aelem.click();
});
});
casper.then(function(){
casper.capture('TestCapture.png');
});
casper.run();
If I run the JS code as is - that is, the waitForSelector part is disabled by if(false) - then everything runs fine.
However, if I enable that part by changing the if(false) to if(true), I get this:

....
I truly don't understand this, because http://docs.casperjs.org/en/latest/modules/casper.html#waitforselector says:
Waits until an element matching the provided selector expression exists in remote DOM to process any next step
... where http://docs.casperjs.org/en/latest/selectors.html says:
CasperJS makes a heavy use of selectors in order to work with the DOM, and can transparently use either CSS3 or XPath expressions.
So, XPath should be OK - what's more, I'm using THE EXACT SAME XPATH in:
var aelem = __utils__.getElementByXPath('//*[text()="Click me!"]');
... and there it works, but it fails in:
casper.waitForSelector('//*[text()="Click me!"]', function() { ....
Why does this happen - where am I going wrong? And how can I use this XPath in waitForSelector, if it's possible?
If you pass a string into the waitForSelector() function, it would be interpreted as a CSS selector. To have it work with an XPath expression pass in an object explicitly specifying the selector type:
selectorObject = {
type: 'xpath',
path: '//*[text()="Click me!"]'
}
casper.waitForSelector(selectorObject, function() {
// ...
});
You can solve it with waitForText() as well, sample here.

CasperJS doesn't follow link on an ASP site

I'm trying to mimic browser behavior on a site built with ASP, which seems to use a lot of javascript based links and UI using CasperJS. I'm pretty stuck, and not sure how what to do next.
I'm using:casperjs1.1.0-beta3,phantomjs1.9.8, and the site url is https://icsid.worldbank.org/apps/ICSIDWEB/cases/Pages/AdvancedSearch.aspx
This is the HTML link I want to click on:
<td>
3
</td>
The site has some SSL configuration problems, so CasperJS is run with some additional flags to work: casperjs --ignore-ssl-errors=true --ssl-protocol=tlsv1 icsid.js
icsid.js just tries to open the site and click on a link to get to the next page of results. I want to check all results.
var casper = require('casper').create({
clientScripts: ["./jquery.min.js"],
verbose: true,
logLevel: 'debug',
pageSettings: {
loadImages: false,
loadPlugins: false,
userAgent: 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.2 Safari/537.36',
}
});
casper.start('https://icsid.worldbank.org/apps/ICSIDWEB/cases/Pages/AdvancedSearch.aspx', function(){});
casper.then(function() {
this.wait(5000);
this.capture('screenshot0.png');
casper.then(function(){
var text = this.evaluate(function(){
return jQuery('.gdcol a')[0].text;
});
console.log('text: ' + text);
this.evaluate(function(){
// try to go to second page
return jQuery('a').filter(function(index) { return $(this).text() === "2"; })[0].click();
});
});
casper.then(function(){
this.wait(5000);
var size = this.evaluate(function(){
return jQuery('.gdcol a').size();
});
console.log('size: ' + size);
// if successfully clicked and changed url, the link text will change
var text = this.evaluate(function(){
return jQuery('.gdcol a')[0].text;
});
console.log('text: ' + text);
// if it's still on the first page, this will be null
var page = this.evaluate(function(){
return jQuery('a').filter(function(index) { return $(this).text() === "1"; })[0].text;
});
console.log('page: ' + page);
// if it's on the second page, this will be null
var page = this.evaluate(function(){
return jQuery('a').filter(function(index) { return $(this).text() === "2"; })[0].text;
});
console.log('page: ' + page);
this.capture('screenshot1.png');
});
});
casper.run();
This is the resulting log:

You shouldn't use Element.click(), because it doesn't do anything in PhantomJS most of the time. Use CasperJS' click() function that tries many thing to properly click an element.
Since CSS selectors don't support matches based on text, you can use XPath to solve this:
var x = require('casper').selectXPath;
...
casper.click(x("//a[text()='2']"));
Your other misconception is that casper.wait() actually does something. All then*() and wait*() functions are asynchronous step functions. When you call them, you're only scheduling a step that should be executed at the end of the current step.
For example, if you call this:
this.wait(5000);
this.capture('screenshot0.png');
this.then(function(){...
it is executed like this:
this.capture('screenshot0.png');
this.wait(5000);
this.then(function(){...
If you can, you should wrap synchronous function calls in a casper.then().

Appium error: uncaughtException: Cannot read property 'executeAtom' of null

I am doing iOS Mobile Application Testing using Selenium. I am using respectives
Appium version 1.3.7
Node JS version 2.7.5
ios webkit debug proxy
iPhone 5c
Xcode version 6.1
I am using a shell script which is helping me to check the ios_webkit_debug_proxy is available or not. If not exists, within 2 seconds, it will start the ios_webkit_debug_proxy.
My testing is working well. But still facing some problem in appium that Appium is stopped certainly giving an uncaught exception: Cannot read property 'executeAtom' of null
I have tried to solve in various ways.
Restart Appium and run again.
Update the appium version to stable latest version 1.4.0. But the
error is still remaining.
Update the Node JS.
Xcode is always opened in run execution time.
Nullify the implicitly wait before every WebDriverWait happens.
Link: http://chon.techliminal.com/ajax_wait/#/intro
Using java uncaught exception handler in every related class. Link:
https://bharatonjava.wordpress.com/2012/09/04/uncaughtexceptionhandler-in-java/
But still error is remaining. Would you please suggest me how I can solve this problem??
For your better understanding I am attaching the log file below.

Set an item from localStorage in a protractor test

describe('The feature', function() {

browser.executeScript('localStorage.setItem("key","value");');
});
it('should do this', function() {
});
});
but i get this error when the test is run against selenium with chromedriver 2.10 and chrome 37
Executing: [execute script: window.localStorage.setItem("key","value");, []])
15:31:29.747 WARN - Exception thrown

Any idea where the problem cam from ?
According to one of the answers at Remove an item from localStorage in a protractor test, this happens when you try to access localStorage without hitting the browser (say, browser.get) first when you are using the Chrome driver. The solution seems to be to hit the browser first (maybe your root page) to get a page loaded in Chrome so that you can manipulate the localStorage. That at least is what I have been doing for our project. Hope this helps!
