Testing

You can write tests for your code using the test keyword:

test "test name" {
  // Your test code here
}

If the test code throws, that counts as the test failing. If the test code runs successfully, then the test passes. You can use the assert keyword to ensure a condition is true in your test, otherwise the test will fail.

test "passing test" {
  assert 2 + 2 == 4
}

test "failing test" {
  assert 2 + 2 == 5
}

You can use any code from the module you’re writing the test in, or have imported from other modules.

import { "std/math" as math }

test "imported module" {
  assert math.sqrt(4) == 2
}

fn square(int n) -> int {
  return n * n
}

test "local function" {
  assert square(2) == 4
}
