How To Create Custom Menus with CSS Select

When it comes to UI components, there are two versatile methods that we can use to build it for your website: either we can use prebuilt components from a well-known library or framework, or we can develop our UI components from scratch.

How To Use driver.FindElement And driver.FindElements In Selenium C#

One of the essential parts when performing automated UI testing, whether using Selenium or another framework, is identifying the correct web elements the tests will interact with. However, if the web elements are not located correctly, you might get NoSuchElementException in Selenium. This would cause a false negative result because we won’t get to the actual functionality check. Instead, our test will fail simply because it failed to interact with the correct element.

How To Handle Dynamic Dropdowns In Selenium WebDriver With Java

Joseph, who has been working as a Quality Engineer, was assigned to perform web automation for the company’s website.

Guide To Find Index Of Element In List with Python Selenium

In an ideal world, you can test your web application in the same test environment and return the same results every time. The reality can be difficult sometimes when you have flaky tests, which may be due to the complexity of the web elements you are trying to perform an action on your test case.

Fault-Based Testing and the Pesticide Paradox

In some sense, testing can be more difficult than coding, as validating the efficiency of the test cases (i.e., the ‘goodness’ of your tests) can be much harder than validating code correctness. In practice, the tests are just executed without any validation beyond the pass/fail verdict. On the contrary, the code is (hopefully) always validated by testing. By designing and executing the test cases the result is that some tests have passed, and some others have failed. Testers do not know much about how many bugs remain in the code, nor about their bug-revealing efficiency.
