Sorry, your blog cannot share posts by email. Here we are in Visual Studio Community Edition for Mac. As we start digging into the code, you will see us using these assertions to be able to set a pass or fail state for all of our test methods. We’re going to go and click download Visual Studio for Mac. For example, here, you can see we are finding an element and then we are clicking on it. Selenium is a set of different software tools each with a different approach to supporting browser automation. Now, we get many options to install different workloads for Visual Studio.

Let me know by leaving a comment below. This is not a comprehensive course on MS Test, but just know that these assertions basically are a key part of all of our tests. In hopefully a not too distant future, Selenium 4 is coming. All TestMethods need to be public and they need to be void.
