Next up, last test case, it ('should allow strings with non-space characters'). I'm going to paste that in the it function and then we can actually set up the test case. You could have provided a bunch of different values as the argument to isRealString. We're still going to make that response variable. We're still going to call isRealString, but right here, I'm going to choose to pass in (' Andrew '), which is valid. The trim function is going to remove those spaces in the validation process:
it('should allow string with non-space characters', () => { var res = isRealString(' Andrew ');});
Down below we can expect that response is true, toBe(true). That's all you needed to do, ...
