Anti-pattern Example: A long test case that tries to assert the existence of error with try-catch

catch-in-test.js

it("When no product name, it throws error 400", async() => {
let errorWeExceptFor = null;
try {
  const result = await addNewProduct({name:'nest'});} 
catch (error) {
  expect(error.code).to.equal('InvalidInput');
  errorWeExceptFor = error;
}
expect(errorWeExceptFor).not.to.be.null;
//if this assertion fails, the tests results/reports will only show
//that some value is null, there won't be a word about a missing Exception
});
