Test Coverage and Code coverage are the most popular methodologies for measuring the effectiveness of the code. Though these terms are sometimes used interchangeably since their underlying principles are the same. But they are not as similar as you may think. Many times, I have noticed the testing team and development team being confused over the use of these two terminologies. Which is why I thought of coming up with an article to talk about the differences between code coverage and test coverage in detail.
A question that has been on the back of minds for many web developers and testers who are involved in cross browser testing.
If you use Selenium WebDriver, you probably know that there are many methods to perform specific actions or interact with elements on a web page. The Selenium Python module gives you the methods you need to be able to automate many tasks when working with a web browser online.
Earlier testers would often refrain from using record and replay tools like Selenium IDE for automation testing and opt for using scripting frameworks like Selenium WebDriver, WebDriverIO, Cypress, etc. The major downside of record & playback (or replay) tools is the inability to leverage tools for writing scalable tests.
Everybody knows Google Chrome is the most popular web browsers in the globe and rightfully so. With a whopping 66 percent share in the browser market worldwide, there is no denying Chrome’s popularity despite the stagnancy in its growth over the last few years. With every single release, Google is trying to make Chrome better by fixing bugs and adding cutting-edge functionalities. Moreover, web developers are coming up with useful extensions for Chrome, which is also one of its best features- its extensibility. If you’re a web developer, the number of Chrome extensions for developers you’ll find in the store can make life easier and boost productivity for you.
