Browser Drivers – As mentioned in the earlier section, Selenium communicates with the web browser through the corresponding browser driver. JSON Wire Protocol – JSON (JavaScript Object Notation) Wire Protocol is a REST (Representational State Transfer) based Application Programming Interface (API) that is responsible for facilitating the transfer of data between different blocks in the WebDriver architecture.ģ. and the same can be downloaded from here.Ģ. There are Selenium Client Libraries for programming languages like C#, Java, Ruby, Python, Perl, etc. Selenium Client Libraries – Selenium Client Libraries, also referred as Selenium Language Bindings is primarily responsible for providing multi-language support for programming languages. The Selenium WebDriver comprises of four crucial blocks-ġ. Selenium WebDriver: Primary Building Blocks
You can download the Selenium WebDriver for popular browsers like Opera, Firefox, Chrome, Internet Explorer, Microsoft Edge, etc. Once the Selenium WebDriver for the corresponding web browser is in your system, you can get started with cross browser testing with Selenium. The approach used by the Selenium WebDriver is entirely different from the one being used by Selenium IDE (GUI based Firefox plugin to do playback and record testing) and Selenium Remote Control (standalone Java program to execute HTML test suites).
Hence, any update in the browser version/features would only involve support for those new features in the WebDriver installed on the test machine. Each browser will have its corresponding WebDriver which is used for communicating with the browser on which tests are performed. The key advantage of using the Selenium WebDriver for Selenium test automation is that the communication with the underlying browser is performed through a browser-specific driver. We will be using the Opera WebDriver to help us run our Selenium testing scripts over the Opera browsers.īefore we get started with Selenium test automation on Opera with Selenium and Python, it is extremely important that we have a look at Selenium WebDriver the core component of the Selenium test framework. With this blog, we will go into the details of how you can perform test automation on Opera with Selenium and Python. When all your resources are already putting their energies on testing other browsers, it becomes challenging to test Opera, and it’s latest and not to forget the legacy versions.įortunately, Selenium is there to help us perform automated browser testing with various browsers and programming languages. You could surely choose to perform cross browser testing manually, but the test process would inevitably hit a roadblock when a newer version of the ‘browser on which the testing is performed’ is released. You simply cannot leave Opera as an afterthought! This could turn up to be a considerable number of leads for your business. 2.17% may look like a small fraction, but we are referring to global statistics, meaning 2.17% of all the internet users. Owing to this, Opera has a market share of around 2.17% globally from July 2019 – July 2020 as per GS StatCounter. This is because Opera performs quite well even at slow internet speeds. What about the other browsers? What about Opera? Opera may not be your default browser, but it still is a popular web browser in the market and is especially loved in areas that don’t have high-speed Internet. When it comes to cross-browser testing, we tend to focus on executing test cases for bigwigs like Google Chrome, Firefox, or Safari.
