整体式

整体式仓库

Molecule通常用于隔离测试剧本或角色。但是，它也可以从整体式仓库进行测试。

$ tree monolith-repo -L 3 --prune
monolith-repo
 ├── library
 │   └── foo.py
 ├── plugins
 │   └── filters
 │       └── foo.py
 └── roles
     ├── bar
     │   └── README.md
     ├── baz
     │   └── README.md
     └── foo
         └── README.md

使用Molecule初始化的角色（在本例中为baz）将通过其converge.yml或元依赖项简单地引用依赖角色。

Molecule可以使用此技术测试复杂的场景。

$ cd monolith-repo/roles/baz
$ molecule test

Molecule只是设置ANSIBLE_*环境变量。要查看Molecule操作期间设置的环境变量，请传递--debug标志。

$ molecule --debug test

Molecule可以用多种方式进行自定义。更新molecule.yml中供应器的env部分以适应开发人员的需求和项目的布局。

provisioner:
  name: ansible
  env:
    ANSIBLE_$VAR: $VALUE
