Recently, I had to repair a Yoga Tab 3 Plus and needed a way to test all of the Components like Sensors, Battery, Speakers...
On most phones, there are secret codes that can be entered in the Dialer App to launch a so called Factory Test Menu, where you can run all sorts of tests on the internal components.
If you have the Wifi-only version of the Tablet, you dont have the Dialer App so you need to launch the Menu otherwise.

After a bit of poking around, here's what I came up with:

At first, you will need to connect your tablet to a PC via USB and get ADB working. Please refer to the following XDA guide on how to do so:
How to Install ADB on Windows, macOS, and Linux

Once all of that is set up, you will need to run the adb shell with the following command:
adb shell

If everything worked, you should see something like this:
YT-X703F:/ $

Now you can type in the following command to launch the menu:
am start -n com.tools.cit/.HomeActivity

Be aware that all of the options are written in Chinese so you have to use another phone to translate it, or use the following translation:

This guide works for the Lenovo Yoga Tab 3 Plus (Model: YT-X703F) but might work for other Qualcomm based Lenovo Tablets as well (not tested).
Note: The app can apparently also be launched with the secret code *#*#7388#*#* but this did not work out for me
