Unit Tester for Minecraft Functions
Simple datapack that will output in chat (console) whether two values are equivalent or not.
Run /function u_test:install before using to add the correct scoreboard objectives.
Before running any set of unit tests, put data modify storage u_test name set value NAME_OF_TEST and function u_test:run/reset at the top of the function to reset the test cases and set a name for the new batch of tests.
Comparing Scoreboard Values
scoreboard players set expected u_test 7
scoreboard players set actual u_test 3
function u_test:run/score
Comparing NBT Storage Values
data modify storage u_test expected set value [1,2,3,4]
data modify storage u_test actual set value [1,2,3,4,5]
function u_test:run/storage
Both of these will throw an assertion error in chat.
At the end of each set of unit tests, put function u_test:run/end_set
At the end of all unit tests, put function u_test:run/end_all
Run /function u_test:sample_tests/main for an example. You can use the function as an example for what to do.
