Shouldn't the bert-based-case and bertBasedCase be bert-base-cased and bertBaseCased?

By the way, why is this model specific? Are we using these values somewhere?

Fixed that typo.

The local bertBasedCase is just a name of that jsonnet variable, it just needs to be a unique string but several punctuation marks are not allowed in variable names. We recommend 1 variable like this per test. On our team we have 1 file per "family" of tests, e.g. 1 file for pytorch resnet50 where the file contains [short test, long test] X [v2-8 TPU, v3-8 TPU, v100 GPU(s)] for the same model on the same ML framework.

The modelName and frameworkPrefix are just used in generating the name of the GKE job. For example, a recent run was named: hf-bert-based-case-example-v3-8-vtgrj. Future runs will look like hf-bert-base-cased-example-v3-8-xxxxx
