Alternative syntaxes

testMatrix(fn, valuesForParam1, valuesForParam1, ...)

Upsides

It allows us to respect how arguments are passed to fn instead of arbitrarily opting for an object.

Downsides

If params are not passed as an object, they will be anonymous in the table snapshot

Example

const mult = (a: number, b: number) => a * b
testMatrix(mult, [1, 2], [3, 4])

const add = ({a, b}) => a + b;
testMatrix(mult, {a: [1, 2], b: [3, 4]})

testMatrix(fn).with(...)

It allows us to respect how arguments are passed to fn instead of arbitrarily opting for an object.

The API is a bit easier to read

Using OOP can result in a more complex API

Example

const mult = (a: number, b: number) => a * b
testMatrix(mult).with([1, 2], [3, 4])

const add = ({a, b}) => a + b
testMatrix(mult).with({a: [1, 2], b: [3, 4]})
