In the tests against static data, unfilled format specifiers can currently be seen. This is because the static data includes cases with different numbers of arguments. If there aren't enough arguments to fill all the format specifiers, Jest just leaves the specifier in place, such as %o for objects.
It should be possible to separate the test cases by class and then have separate methods per class, so that the test name format strings can be appropriate.
