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.
