toContain
Check if something is contained in something
This comparison is used to determine if an Array contains a value.
All the values returned by
T[index]
will be compared using the ==
operator, so overloading the class @operator("==")
can be used in conjunction with this comparison. The index
must be a number value, and there must be a length
property that matches the index
type. All values from 0
to length - 1
will be checked.const data = new Uint8Array(100);
data[5] = 255;
expect(data).toContain(255);
This method is portable with
jest
using the toContain()
method.Last modified 3yr ago
