Troubleshooting Click Function Issues in Protractor Scripts

Troubleshooting Click Function Issues in Protractor Scripts

5 April 2024 Stephan Petzl Leave a comment Tech-Help

If you’re automating tests with Protractor and Appium for an AngularJS application and encounter issues with the click() function, such as a lack of redirection or no visible on-click effect, even though the element is correctly located, this guide is for you.

Understanding the Problem

You’ve written a script where the sendKeys() function is working fine for username and password fields, but the click() event on the login button doesn’t trigger the expected behavior. The script passes without errors, but the login button doesn’t seem to respond.

Here’s a snippet of your test script:

                
"use strict";
require("jasmine-expect");
var wd = require("wd");
describe('my app', function() {
    it('should make the login test',function() {
        // other code
        element(by.model('credentials.username')).sendKeys('RET02');
        element(by.model('credentials.password')).sendKeys('RET02');
        element(by.css('.login-button')).click();
        browser.sleep(8000);
        expect(browser.getCurrentUrl()).not.toEqual("http://10.0.22.82:8080/jws/fetablet/#/login");
    });
});
                
            

Potential Solutions

There could be various reasons why the click() event isn’t working as expected. Here are some strategies to resolve the issue:

  • Improve the Button Locator: Ensure that you’re targeting the correct element by using a more specific CSS selector.
element(by.css(".login-form .login-button")).click();
  • Wait for Element to be Clickable: Use Protractor’s Expected Conditions to wait until the element is actionable before attempting to click it.
  • var EC = protractor.ExpectedConditions;
    var loginButton = element(by.css('.login-form .login-button'));
    browser.wait(EC.elementToBeClickable(loginButton), 5000);
    loginButton.click();
  • Introduce a Delay: Sometimes adding a short delay before the click can help.
  • browser.sleep(500);
    element(by.css('.login-form .login-button')).click();
  • Double Click: As unconventional as it sounds, clicking the button twice might do the trick.
  • loginButton.click();
    loginButton.click();
  • Use Browser Actions: Simulate the mouse movement and click through browser actions.
  • browser.actions().mouseMove(loginButton).click().perform();
  • Click via JavaScript: If all else fails, you can try triggering the click event directly with JavaScript.
  • browser.executeScript("arguments[0].click();", loginButton);

    After attempting the click, instead of using browser.sleep(), you can wait for the URL to change as a more reliable method to verify the success of the login action.

    Conclusion

    When dealing with automation scripts, particularly in Protractor and Appium, it’s important to experiment with different approaches to find the one that works reliably for your specific scenario. Starting with the most straightforward solutions and gradually moving towards the more complex ones often yields the best results. Try these methods to ensure your click() function performs as expected and leads to successful test automation.
