testing

API Reference

Structs

`struct Failure`

A failed test assertion and the test that produced it.

`struct TestCase`

A named test and the block that runs it.

Effects

`effect 'fail(message: String) -> ()`

Reports a failed assertion to the active test runner and then resumes the test.

`effect 'registerTest(testCase: TestCase) -> ()`

Registers a test case during test-module initialization.

Functions

`func test(consume _ name: String, consume _ block: () -> ()) 'registerTest`

Registers block under name without running it immediately.

`func assert(_ condition: Bool) 'fail`

Reports the default assertion message when condition is false.

`func assertMessage(_ condition: Bool, _ message: String) 'fail`

The pre-reset stdlib's name for assert_message; existing programs (talk-syntax among them) call it, so it stays as an alias.

`func assert_message(_ condition: Bool, _ message: String) 'fail`

Reports message when condition is false and then resumes execution.

`func report(tests: [TestCase], failures: [Failure])`

Prints either a passing count or every recorded failure.
