Here are some ways to automate video streaming testing on different devices and platforms:

• Use a cloud-based testing platform. A cloud-based testing platform gives you access to a variety of devices and browsers, so you can automate your tests on a wide range of platforms. This can save you time and money, as you do not need to purchase and maintain your own devices and browsers.
• Use a test automation framework. A test automation framework is a set of tools and processes that help you automate your tests. This can make it easier to create and maintain your test scripts, and it can also help you to ensure that your tests are consistent and repeatable.
• Use a scripting language. A scripting language, such as Python or JavaScript, can be used to automate your tests. This can give you more flexibility in how you write your test scripts, and it can also make it easier to integrate your tests with other systems.
• Use a test management tool. A test management tool can help you to track your test cases, test results, and defects. This can help you to manage your testing process and ensure that your tests are effective.
