jasmine parameterized unit test

Based on piotrek’s answer and the article Parameterized testing in Javascript, you could also use the following approach which uses ES6 syntax:

[
  ['abc', 3],
  ['ab', 2],
  ['', 0],
].forEach(([string, expectedLength]) => {
  it(`should return length ${expectedLength} for string "${string}"`, () => {
    expect(string.length).toBe(expectedLength);
  });
});

I have tested it with the Jest test framework, but it should work with Jasmine as well.
