Guide to executing various datasets as parameters for test cases in Cypress using Typescript

I am encountering an issue while trying to run a testcase with multiple data fixtures constructed using an object array in Cypress. The error message states: TS2345: Argument of type '(fixture: { name: string; sValue: string; eValue: string}) => void' is not assignable to parameter of type '(value: { name: string; sValue: string; eValue: string}, index: number, array: { name: string; sValue: string; eValue: string; }[]) => void'. Can anyone explain why this error occurs and what mistake I might have made?

const Fixtures = [
  {
    name: 'name1',
    sValue: 'a',
    eValue: '1',
  },

  {
    name: 'name2',
    sValue: 'b',
    eValue: '2',
  },
];
Fixtures.forEach(
  (fixture: {
    name: string;
    sValue: string;
    eValue: string;
  }) => {
    describe(`${fixture.name} test`, () => {
      it(`set value ${fixture.sValue}`, () => {
        ...
      });

      it(`check ${fixture.name} on ${fixture.sValue}`, () => {
        ...
      });

      it('check test4', () => {
        ...
      });

      it('check testcase 5', () => {
        ...
      });
    });
  }
);

Answer №1

Loop through Fixtures array and for each fixture execute the following steps:
describe `${fixture.name} test` 
it `set value ${fixture.sValue}`
...

Finish looping through all fixtures without reinitializing the object inside the loop.
