Global Classes

Example on how to test global classes

Overview

When it comes to Static Global Classes (like vCACCAFEFilterParam for example), they need to be defined before each test, with the methods that you want to use inside your test.

Example

Example Class:

export default function ( date: string): string {
  Server.log( "Getting date" );
  return vCACCAFEFilterParam.date( date );
}

Example test:

import testOne from "./testOne";

describe('', function () {
  beforeEach(()=>{
    (<any> vCACCAFEFilterParam)   = {
      date: function ( date: string ) {
        throw new Error( "Not Supported" );
      }
    };
  });

  afterEach(() => {
    (<any> vCACCAFEFilterParam)   = undefined;
  });

  it('should ', function () {
    spyOn( Server, "log" ).and.callFake( () => {} );
    spyOn( vCACCAFEFilterParam, "date" ).and.returnValue( "spy" );

    expect( testOne( 'test' ) ).toBe( "spy" );

    expect( vCACCAFEFilterParam.date ).toHaveBeenCalledTimes( 1 );
    expect( Server.log ).toHaveBeenCalledTimes( 1 );
  });
});
