Introduction

This library provide a set of matchers for Jasmine to make life easier and code more readable 👍

Matchers

Following matchers are added for joi:

expect(...).toBeJoiError();
expect(...).toBeJoiErrorWith({ path: '', type: '' });

Following matchers are added for monet.js:

expect(...).toBeEither();
expect(...).toBeLeftEither();
expect(...).toBeLeftEitherWith('something');
expect(...).toBeMaybe();
expect(...).toBeNone();
expect(...).toBeRightEither();
expect(...).toBeRightEitherWith('something');
expect(...).toBeSome();
expect(...).toBeSomeWith();

Utilities

Following convenience functions are added for Jasmine

createSpyObjFrom

This one makes mocking objects slightly more convenient. Instead of jasmine.createSpyObj('name', ['method']) you can do jasmine.createSpyObjFrom(Class). It tries to infer the methods from the prototype and is able to account for inheritance as well.

Integration

Node.js and TypeScript

Update your Jasmine boostrap file:

require('@trademachines/jasmine-utils');

Also, don't forget to add them to your list of types in tsconfig.json like so:

{
  "compilerOptions": {
    "types": [
      "node",
      "jasmine",
      "@trademachines/jasmine-utils"
    ]
  }
}
