A test block is a technical block that is used for game tests.
Obtaining
Test blocks are available in the Creative inventory, under the Operator Utilities tab, and using the /setblock, /fill, or /give commands. When placed, test blocks are unbreakable in Survival and have the same blast resistance as bedrock.
Usage
Cannot be placed in Survival. When placed, use the test block to open its GUI. The GUI opens only if the player is in Creative mode, and has permission level 2 or higher.
Start
Triggers a redstone pulse when the test starts.
Log
Logs a message to the log file when powered by redstone.
Fail
Fails the assigned test when powered by redstone.
Accept
Completes the assigned test when powered by redstone.
