@rbxts/expect > extendNOPs

extendNOPs() function​

Add additional NOOPs to expect().

Signature:

declare function extendNOPs(methods: ReadonlyArray<string>): void;

Parameters​

Parameter

Type

Description

methods

ReadonlyArray<string>

An array of property names to use as NOOPs

Returns:

void

Remarks​

A NOOP is a property that does nothing. It's just there to make the test easier to read.

For example:

expect("Daymon").to.have.the.substring("Day");

In this case, to, have, and the are all NOOPs.

Example​

// augment the expect module so typescript knows the properties exists
declare module "@rbxts/expect" {
  interface Assertion<T> {
    readonly to: this;
    readonly have: this;
    readonly the: this;
  }
}

// add the properties to expect for runtime usage
extendNOPs(["to", "have", "the"]);
