Two Fer in Go
Create a sentence of the form "One for X, one for me."
exercism fetch go two-fer
2-fer is short for two for one. One for you and one for me.
"One for X, one for me."
When X is a name or "you".
If the given name is "Alice", the result should be "One for Alice, one for me." If no name is given, the result should be "One for you, one for me."
As programmers mature, they eventually want to test their code.
Here at Exercism we simulate Test-Driven Development (TDD), where you write your tests before writing any functionality. The simulation comes in the form of a pre-written test suite, which will signal that you have solved the problem.
It will also provide you with a safety net to explore other solutions without breaking the functionality.
A typical TDD workflow on Exercism:
- Run the test file and pick one test that's failing.
- Write some code to fix the test you picked.
- Re-run the tests to confirm the test is now passing.
- Repeat from step 1.
- Submit your solution (
exercism submit /path/to/file)
Submissions are encouraged to be general, within reason. Having said that, it's also important not to over-engineer a solution.
It's important to remember that the goal is to make code as expressive and readable as we can.
Running the tests
To run the tests run the command
go test from within the exercise directory.
If the test suite contains benchmarks, you can run these with the
go test -bench .
Keep in mind that each reviewer will run benchmarks on a different machine, with different specs, so the results from these benchmark tests may vary.

This is an exercise to introduce users to basic programming constructs, just after hello World. https://en.wikipedia.org/wiki/Two-fer
Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
