Runs a test function with all possible combinations of its parameters.
Usage
Sync only
const result = []
const testVariants = createTestVariants(({a, b, c}: { a: number, b: string, c: boolean }) => {
result.push([a, b, c])
})
const count = await testVariants({
a: [1, 2],
b: ['3', '4'],
c: [true, false],
})({
pauseInterval: 10000, // pause after each 10 seconds and log inerations count, it needed for karma tests
pauseTime: 10, // continue after 10 milliseconds
})
// result == [
// [1, '3', true],
// [1, '3', false],
// [1, '4', true],
// [1, '4', false],
// [2, '3', true],
// [2, '3', false],
// [2, '4', true],
// [2, '4', false],
// ]
// count == 8
Async
const result = []
const testVariants = createTestVariants(async ({a, b, c}: { a: number, b: string, c: boolean }) => {
await delay(10)
result.push([a, b, c])
})
const count = await testVariants({
a: [1, 2],
b: ['3', '4'],
c: [true, false],
})() // no extra parameters
Calculable variants
const result = []
const testVariants = createTestVariants(async ({a, b, c}: { a: number, b: number, c: number }) => {
await delay(10)
result.push([a, b, c])
})
const count = await testVariants({
a: [1, 2],
b: ({a}) => [ a + 1, a + 2 ], // you can use 'a', but you can't use 'c' because it will initialize after 'b'
c: ({a, b}) => [ a, b, a + b ],
})()
