"Chrome, Firefox and Safari, Opera, Internet Explorer" why do not want to install it?

I am interested in the question of software testing, when the product has already been created, but not yet tested (we will talk about products using the .NET Framework).

So, let's say I want my application to work on the following OS: Windows Vista, 7, 8, 8.1, 10.
By the way, among other things, DirectX Media Foundation is used.

The questions are:

• Is there a difference between testing on a 32- and 64-bit OS?
• If I test a product under, for example, Windows 7, should I also test it with the Service Pack installed?
• Where can I find ISO images of the required OS versions for testing purposes (virtualization in VMware)?

What query to check that the values in a column are rounded, for example, to 3 decimal places? Or Inverse query that there are no values other than three-digit rounding.

Please tell me how to run Jmeter script from Jenkins using JRE, not JDK. The system variables contain the path to the JRE. But when run from Jenkins, the JDK is included.

You can use distinct function
