Answer 1

The vim-projectionist plugin .
The config is set via the "g:projectionist_heuristics" variable (JSON => VimL) or via the ".projections.json" file, which must be located in the root directory of the project.

{
  "src/Foo/Bar/*.php": {
    "alternate": "spec/Foo/Bar/{}Spec.php",
    "type": "src"
  },
  "spec/Foo/Bar/*Spec.php": {
    "alternate": "src/Foo/Bar/{}.php",
    "type": "spec"
  }
}

:AV The vim-altr plugin
just opens files as a rule, without splitting.

call altr#define('src/*/%.php', 'spec/*/%Spec.php')
