I have an array:
Const domesticAnimals = ['Chicken','lama','Donkey']
Const wildAnimals =['lama','lion','elephant']
How do I test If any wildAnimals is listed in domesticAnimals array?
I have tried
test('test If any wild animal is in the domestic animal list', async() =>{
expect(domesticAnimals ).toContain('lama')
}) //works perfectly
test('test If any wild animal is in the domestic animal list', async() =>{
expect(domesticAnimals ).toContain(wildAnimals) // does not work
})
You actually have TWO arrays:
const domesticAnimals = ['Chicken','lama','Donkey'];
const wildAnimals =['lama','lion','elephant'];
The plain JS way of testing if one array contains any values from the other would be:
domesticAnimals.some(domesticAnimal => wildAnimals.includes(domesticAnimal));
So to put this in a test, would be:
test('test If any wild animal is in the domestic animal list', () =>{
expect(domesticAnimals.some(
domesticAnimal => wildAnimals.includes(domesticAnimal)
)).toBe(true);
});
As a side-note, you marked the test functions as async but don't actually await anything, so the async is redundant.
