"Exploring Mocha and Chai: Tips for Generating a Comprehensive List of Errors in Test Cases

I am currently working on a unit test to validate a list of elements.

Example:

arr = [
{ element : "aaa",
  validation : false
},
{ element: "bbbb",
  validation: true
},
{ element: "ccc",
  validation: false
}

While running my unit test, I encountered an issue where Mocha and Chai would stop at the first invalid element. How can I make Mocha continue the test even if it encounters an error?

This is my current code for the "it" block:

it('Read element', () => {
    let length = arr.length - 1;
      for (let i =0; i<= length; i++ ) {
    assert.equal(arr[i].validation, true, 'route ' + arr[i].element+ ' should be valid');
      }
});

Answer №1

To ensure accuracy, individual tests can be generated for each element within the array:

describe('Check element', () => {
  arr.forEach(item => {
    it('route ' + item.element + ' must have valid route', () => {
      assert.equal(item.validation, true);
    });
  });
});

Answer №2

Instead of manually iterating through your array and building another array to compare against, consider using the deepEqual matcher for a more efficient approach.

let expectedArray = arr = [
{ element : "aaa",
  validation : true
},
{ element: "bbbb",
  validation: true
},
{ element: "ccc",
  validation: true
}];

assert.deepEqual(arr, expectedArray);
