如何使用mix运行测试

Question

更新：对于从Google收到此问题的任何人，您可以通过运行mix test来运行给定Elixir项目的mix test 。

根据文档 ，Elixir脚本文件（扩展名为.exs）在运行之前不需要编译。

以下是Elixir文档的确切引用：

测试文件是Elixir脚本文件（.exs）。 这很方便，因为我们不需要在运行它们之前编译测试文件

所以我增加了模块文件和测试文件到图书馆骗子这里

我已经通过在项目根目录中运行mix compile项目。

当我尝试使用mix test运行除了新测试文件之外的所有测试文件时，问题就出现了。 我收到以下错误：

** (CompileError) test/faker/shakespeare_test.exs:3: module Faker.Shakespeare is not loaded and could not be found
    (stdlib) lists.erl:1353: :lists.mapfoldl/3
    (stdlib) lists.erl:1354: :lists.mapfoldl/3

错误说无法找到该模块，但它显然在bin中。 我究竟做错了什么？

    assert String.length(hamlet_quote) != 0

Answer 1

您正在定义模块（不是类） Shakespeare但您的测试使用的是模块Faker.Shakespeare 。

如果您正确地将模块名称定义为defmodule Faker.Shakespeare ，它应该可以工作。
