hs-test: use consistent naming convention

Exported indentifiers in Go start with capital letters. Only few fields
in hs-test, which are being unmarshaled from yaml are required to be
exported. Every other field name or method name should start with
lower-case letter, to be consistent with this naming convention.

Type: test
