How To Deal With “Element is not clickable at point” Exception Using Selenium

Any automation testing using Selenium (or Cypress) involves interacting with the WebElements available in the DOM. Test automation framework underpins a diverse set of locators that are used to identify and interact with any type of element on the web page. For example, ID, name, className, XPath, cssSelector, tagName, linkText, and partialLinkText are some of the widely used that help you interact with the elements on the web page. These locators help you perform any type of web element interactions using Selenium.

Complete JUnit 5 Mockito Tutorial For Unit Testing

Mockito is a unit testing framework for Java that simplifies the task of automation testing. It makes unit testing highly effective with clean tests, thanks to dependency injection and compile-time checks. In addition, Mockito helps improve the test independence of components being developed by helping you create objects that have no dependencies on a test-specific configuration. The most popular way of using Mockito is within the JUnit framework to help you write better tests.

Complete Selenium WebDriver Tutorial: Guide to Selenium Test Automation

When it comes to web automation testing, there are a number of frameworks like Selenium, Cypress, PlayWright, Puppeteer, etc., that make it to the ‘preferred list’ of frameworks. The choice of test automation framework depends on a range of parameters like type, complexity, scale, along with the framework expertise available within the team. However, it’s no surprise that Selenium is still the most preferred framework among developers and QAs.

Complete Automation Testing – Is It Feasible?

It is a fact that software testing is time and resources consuming. Testing the software can be observed from different perspectives. It can be divided based on what we are testing. For example, each deliverable in the project, like the requirements, design, code, documents, user interface, etc., should be tested. Moreover, we may test the code based on the user and functional requirements or specifications, i.e., black-box testing. At this level, we are testing the code as a black box to ensure that all services expected from the program exist, work as expected, and with no problem. We may also need to test the structure of the code, i.e., white box testing. Testing can also be divided based on the sub-stages or activities in testing, for instance, test case generation and design, test case execution and verification, building the testing database, etc. Testing ensures that the developed software is, ultimately, error-free. However, no process can guarantee that the developed software is 100% error-free.

How To Automate Login Page Using Selenium WebDriver?

Selenium has always been the most preferred test automation framework for testing web applications. This open-source framework supports popular programming languages (e.g. Java, JavaScript, Python, C#, etc.), browsers, and operating systems. It can also be integrated with other test automation frameworks like JUnit, TestNG, PyTest, PyUnit, amongst others. As per the State of open source testing survey, Selenium is still the king for web automation testing, with 81% of organizations preferring it over other frameworks.
