history of test command as [

Does anyone know which came first for the test syntax: test <expr> or [ <expr> ]? My vague understanding is that test was the initial way to do it. But if so, when was the [ syntax introdcued? thanks...

test came first. [ came soon after. Both happened in the 70's and I don't know the years. test and [ were links to the same external program. To sh, these were just another external program.
