- def deepStrictEqual(actual: Any, expected: Any, message: String = js.native): Unit
Generally identical to assert.deepEqual() with two exceptions.
Generally identical to assert.deepEqual() with two exceptions. First, primitive values are compared using the strict equality operator ( === ). Second, object comparisons include a strict equality check of their prototypes.

- def doesNotThrow(block: Function, error: |[RegExp, Function] = js.native, message: String = js.native): Unit
Asserts that the function block does not throw an error.
Asserts that the function block does not throw an error. See assert.throws() for more details. When assert.doesNotThrow() is called, it will immediately call the block function. If an error is thrown and it is the same type as that specified by the error parameter, then an AssertionError is thrown. If the error is of a different type, or if the error parameter is undefined, the error is propagated back to the caller.

- def ok(value: Any, message: String = js.native): Unit
Tests if value is truthy.
Tests if value is truthy. It is equivalent to assert.equal(!!value, true, message). If value is not truthy, an AssertionError is thrown with a message property set equal to the value of the message parameter. If the message parameter is undefined, a default error message is assigned.
