Developers often remark that the tests may contain the same algorithms that the production code does. This feels like redundancy and makes them wonder if TDD is promoting bad practices.

When TDD was first suggested, there were many who were dubious about the wisdom of having developers write tests of their own code. Among the objections raised was that developers will slow down if you burden them with new tasks, namely writing the tests as well as the code. This seems logical.

Part of the TDD process consists of writing failing tests before the code that will eventually make them pass. Test-first alone is not TDD per se, but it is a part of it. When tests are written before production code, this has several beneficial effects.
