Runs a test function with all possible combinations of its parameters.

Usage

Sync only

1const result = []
2const testVariants = createTestVariants(({a, b, c}: { a: number, b: string, c: boolean }) => {
3    result.push([a, b, c])
4})
5const count = await testVariants({
6    a: [1, 2],
7    b: ['3', '4'],
8    c: [true, false],
9})({
10  pauseInterval: 10000, // pause after each 10 seconds and log inerations count, it needed for karma tests
11  pauseTime: 10, // continue after 10 milliseconds
12})
13
14// result == [
15//     [1, '3', true],
16//     [1, '3', false],
17//     [1, '4', true],
18//     [1, '4', false],
19//     [2, '3', true],
20//     [2, '3', false],
21//     [2, '4', true],
22//     [2, '4', false],
23// ]
24// count == 8

Async

1const result = []
2const testVariants = createTestVariants(async ({a, b, c}: { a: number, b: string, c: boolean }) => {
3  await delay(10)
4  result.push([a, b, c])
5})
6const count = await testVariants({
7    a: [1, 2],
8    b: ['3', '4'],
9    c: [true, false],
10})() // no extra parameters

Calculable variants

1const result = []
2const testVariants = createTestVariants(async ({a, b, c}: { a: number, b: number, c: number }) => {
3  await delay(10)
4  result.push([a, b, c])
5})
6const count = await testVariants({
7    a: [1, 2],
8    b: ({a}) => [ a + 1, a + 2 ], // you can use 'a', but you can't use 'c' because it will initialize after 'b' 
9    c: ({a, b}) => [ a, b, a + b ],
10})()
