It would be nice to be able to get the length of a matrix list. In our specific case, we use matrix runs to parallelize a suite of tests, but it requires us to configure the total number of test runner instances we will be using. e.g.
strategy: matrix: instance: [0, 1, 2] ... env: TOTAL_TEST_GROUPS: 3
It would be nice to be able to either get the entire
instance list and/or be able to get the length of it.
