I'm wondering whether measuring conditional code coverage by current tools for Java are not obsolete since Java 8 came up. With Java 8's Optional and Stream we can often avoid code branches/loops, which makes it easy to get very high conditional coverage without testing all possible execution paths. Let's compare old Java code with Java 8 code :

Before Java 8:

public String getName(User user) {
    if (user != null) {
        if (user.getName() != null) {
            return user.getName();
        }
    }
    return "unknown";
}

There are 3 possible execution paths in the above method. In order to get 100% of conditional coverage we need to create 3 unit tests.

Java 8:

public String getName(User user) {
    return Optional.ofNullable(user)
                   .map(User::getName)
                   .orElse("unknown");
}

In this case, branches are hidden and we only need 1 test to get 100% coverage and it doesn't matter which case we will test. Though there are still the same 3 logical branches which should be covered I believe. I think that it makes conditional coverage statistics completely untrusted these days.

Does it make sense to measure conditional coverage for Java 8 code? Are there any other tools spotting undertested code?
