# Launch & Monitor Your Test ### QA your test * [ ] Using Preview Mode function, open your test variant in a new window. * [ ] When previewing you will see the preview toggle at the bottom of the screen. You can switch between the A and B sides of the test using this toggle. * [ ] If you are previewing a theme test, run through your entire website, from homepage to checkout, to ensure your pages are displaying and functioning correctly. {% hint style="info" %} Use our in-depth [QA checklist](https://docs.shoplift.ai/test/qa-checklist) to ensure that your tests are all set to launch, and look good once you've set them live. {% endhint %} ### Launch your test If everything looks good, you're now ready to launch your test! When your test is launched it will be published immediately and your site visitors will begin to see the new variant on your storefront according to your test parameters. {% hint style="info" %} **FAQ: Can I run multiple tests at the same time?** The short answer is yes! Shoplift uses a sophisticated mutual exclusion system to prevent major interactions between active tests. See [Running Multiple Tests Simultaneously](https://docs.shoplift.ai/test/running-multiple-tests-simultaneously) for more information. {% endhint %} ### Check your live test Now that your test is live, we recommend opening a few incognito browsers and navigating to your tested page(s) to ensure that everything is working as expected. If you notice any mistakes, you can always pause your test to make your fixes, and resume it once the fixes are made. Depending on your traffic allocation between your original and variant, you may need to open and close a few incognito browsers before you are sent to the test variant. {% hint style="info" %} If you have any concerns about launching your test, feel free to start a chat with our [Customer Support](https://docs.shoplift.ai/get-started/quickstart/broken-reference) team or email for assistance. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
