Test case with multiple invalid input

[yanghengtang]

For every negative test case, you would usually want to only have 1 invalid input while ensuring everything else is valid

In the following case, there is 2 invalid input: invalid index and missing parameters.

A better way forward could be to split this into 2 test case for each invalid input.
