*Note:* This plugin does not run tests. It justs loads/displays a coverage report generated by a test suite.
To run tests from neovim with coverage enabled, try one of these plugins:
* [neotest](https://github.com/nvim-neotest/neotest)
* [vim-test](https://github.com/vim-test/vim-test)
## Installation
This plugin depends on [plenary](https://github.com/nvim-lua/plenary.nvim) and optionally on the
[lua-xmlreader](https://luarocks.org/modules/luarocks/lua-xmlreader) luarock to parse the cobertura format.
Using vim-plug (not including the luarock dependency):
```vim
Plug 'nvim-lua/plenary.nvim'
Plug 'andythigpen/nvim-coverage'
```
The following lua is required to configure the plugin after installation.
```lua
require("coverage").setup()
```
Using packer:
```lua
use({
"andythigpen/nvim-coverage",
requires = "nvim-lua/plenary.nvim",
-- Optional: needed for PHP when using the cobertura parser
rocks = { 'lua-xmlreader' },
config = function()
require("coverage").setup()
end,
})
```
## Configuration
See [docs](https://github.com/andythigpen/nvim-coverage/blob/main/doc/nvim-coverage.txt) for more info.
Example:
```lua
require("coverage").setup({
commands = true, -- create commands
highlights = {
-- customize highlight groups created by the plugin
covered = { fg = "#C3E88D" }, -- supports style, fg, bg, sp (see :h highlight-gui)
uncovered = { fg = "#F07178" },
},
signs = {
-- use your own highlight groups or text markers
covered = { hl = "CoverageCovered", text = "▎" },
uncovered = { hl = "CoverageUncovered", text = "▎" },
},
summary = {
-- customize the summary pop-up
min_coverage = 80.0, -- minimum coverage threshold (used for highlighting)
},
lang = {
-- customize language specific settings
},
})
```
## Extending to other languages
1. Create a new lua module matching the pattern `coverage.languages.` where `` matches the vim filetype for the coverage language (ex. python).
2. Implement the required methods listed below.
Required methods:
```lua
local M = {}
--- Loads a coverage report.
-- This method should perform whatever steps are necessary to generate a coverage report.
-- The coverage report results should passed to the callback, which will be cached by the plugin.
-- @param callback called with results of the coverage report
M.load = function(callback)
-- TODO: callback(results)
end
--- Returns a list of signs that will be placed in buffers.
-- This method should use the coverage data (previously generated via the load method) to
-- return a list of signs.
-- @return list of signs
M.sign_list = function(data)
-- TODO: generate a list of signs using:
-- require("coverage.signs").new_covered(bufnr, linenr)
-- require("coverage.signs").new_uncovered(bufnr, linenr)
end
--- Returns a summary report.
-- @return summary report
M.summary = function(data)
-- TODO: generate a summary report in the format
return {
files = {
{ -- all fields, except filename, are optional - the report will be blank if the field is nil
filename = fname, -- filename displayed in the report
statements = statements, -- number of total statements in the file
missing = missing, -- number of lines missing coverage (uncovered) in the file
excluded = excluded, -- number of lines excluded from coverage reporting in the file
branches = branches, -- number of total branches in the file
partial = partial_branches, -- number of branches that are partially covered in the file
coverage = coverage, -- coverage percentage (float) for this file
}
},
totals = { -- optional
statements = total_statements, -- number of total statements in the report
missing = total_missing, -- number of lines missing coverage (uncovered) in the report
excluded = total_excluded, -- number of lines excluded from coverage reporting in the report
branches = total_branches, -- number of total branches in the report
partial = total_partial_branches, -- number of branches that are partially covered in the report
coverage = total_coverage, -- coverage percentage to display in the report
}
}
end
return M
```
