Elixir: Genservers

🚧 In development

Instructions

🚧 In development

The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.

In my environment the code works, but not here 🤨

My code is different from the teacher's one 🤔

I've read the lessons but nothing is clear 🙄

Прочитал урок — ничего не понятно 🙄

Your exercise will be checked with these tests:

defmodule Test do
  use ExUnit.Case

  describe "solution genserver work" do
    test "initialization work" do
      {:ok, pid} = Solution.start_link()

      assert Process.alive?(pid)
      Process.exit(pid, :normal)
    end

    test "current_state work" do
      {:ok, pid} = Solution.start_link(%{test: "value"})

      assert Solution.current_state() == %{test: "value"}
      Process.exit(pid, :normal)
    end

    test "reset work" do
      {:ok, pid} = Solution.start_link(%{test: "value"})

      assert Solution.reset() == :ok
      assert Solution.current_state() == %{}
      Process.exit(pid, :normal)
    end

    test "has? work" do
      {:ok, pid} = Solution.start_link(%{test: "value"})

      assert Solution.has?(:test)
      refute Solution.has?(:some)
      Process.exit(pid, :normal)
    end

    test "add work" do
      {:ok, pid} = Solution.start_link(%{test: "value"})

      assert Solution.add(:some, 2) == :ok
      assert Solution.current_state() == %{test: "value", some: 2}
      Process.exit(pid, :normal)
    end

    test "drop work" do
      {:ok, pid} = Solution.start_link(%{test: "value"})

      assert Solution.drop(:some) == :ok
      assert Solution.current_state() == %{test: "value"}
      assert Solution.drop(:test) == :ok
      assert Solution.current_state() == %{}
      Process.exit(pid, :normal)
    end
  end
