# Custom `Testcase` Compiler Failures. _All_ tests this module should **always fail**. It tests that compiling a `testcase` with a custom `Testcase` catches type issues. To compile and run the tests: ```shell ZEOLITE_PATH=$(zeolite --get-path) zeolite -p $ZEOLITE_PATH -r tests/custom-testcase zeolite -p $ZEOLITE_PATH -t tests/custom-testcase ``` _Every_ test should fail with an error related to `custom testcase`.
