------------------------------------------
Hey [~oscarlvp] [~ggregory]
I ran the tests with an empty array returned from {{{}data(){}}}, and they
failed. The issue is that {{@Parameterized}} requires at least one set of
parameters to instantiate the test class. When {{data()}} returns an empty
array, the test runner cannot create an instance of the test class, which
results in a failure.
My changes:
{code:java}
public static String[] data() {
// return MessageDigestAlgorithms.values();
return new String[0];
} {code}
For reference, here are the errors
{code:java}
