A test block is a technical block that is used for game tests.
Obtaining
[edit | edit source]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
[edit | edit source]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
[edit | edit source]Emits a constant redstone signal, similarly to a block of redstone, when the test starts. This block is required to be part of the structure of a block-based test.
Log
[edit | edit source]Logs a message to the server log every time it receives a redstone signal. The message is set in the block's GUI. This has a speech bubble texture.
Fail
[edit | edit source]Causes a test to fail when it receives a redstone signal. This has a frowning face texture.
Accept
[edit | edit source]Causes a test to pass when it receives a redstone signal. This block is required to be part of the structure of a block-based test. This has a smiling face texture.
