--- ## Testing module for lualines statusline
|
||||
---
|
||||
--- ###Uses:
|
||||
---
|
||||
--- Create a new instance with status width 120 & for active statusline
|
||||
--- like following.
|
||||
---
|
||||
--- ``lua
|
||||
--- local statusline = require('tests.statusline').new(120, 'active')
|
||||
--- ```
|
||||
---
|
||||
--- To create a new instance with status width 80 & for inactive statusline use following.
|
||||
---
|
||||
--- ``lua
|
||||
--- local statusline = require('tests.statusline').new(120, 'inactive')
|
||||
--- ```
|
||||
---
|
||||
--- Now setup the state you want to test.
|
||||
--- To test you'll call `expect` method on statusline for example.
|
||||
---
|
||||
--- To create a new instance with status width 80 & tabline
|
||||
---
|
||||
--- ``lua
|
||||
--- local statusline = require('tests.statusline').new(120, 'tabline')
|
||||
--- ```
|
||||
---
|
||||
--- Now setup the state you want to test.
|
||||
--- To test you'll call `expect` method on statusline for example.
|
||||
---
|
||||
--- ``lua
|
||||
--- statusline:expect([===[
|
||||
--- highlights = {
|
||||
--- 1: lualine_c_inactive = { bg = "#3c3836", fg = "#a89984" }
|
||||
--- }
|
||||
--- |{1: [No Name] }
|
||||
--- {1: }
|
||||
--- {1: 0:1 }|
|
||||
---
|
||||
---]===])
|
||||
--- ```
|
||||
---
|
||||
--- For more flexibility you can match a pattern in expect block.
|
||||
--- ``lua
|
||||
--- statusline:expect([===[
|
||||
--- highlights = {
|
||||
--- 1: lualine_a_tabs_inactive = { bg = "#3c3836", bold = true, fg = "#a89984" }
|
||||
--- 2: lualine_transitional_lualine_a_tabs_inactive_to_lualine_a_tabs_active = { bg = "#a89984", fg = "#3c3836" }
|
||||
--- 3: lualine_a_tabs_active = { bg = "#a89984", bold = true, fg = "#282828" }
|
||||
--- 4: lualine_transitional_lualine_a_tabs_active_to_lualine_c_normal = { bg = "#3c3836", fg = "#a89984" }
|
||||
--- 5: lualine_c_normal = { bg = "#3c3836", fg = "#a89984" }
|
||||
--- }
|
||||
--- {MATCH:|{1: %d+ }}
|
||||
--- {MATCH:{1: %d+ }}
|
||||
--- {2:}
|
||||
--- {MATCH:{3: %d+ }}
|
||||
--- {4:}
|
||||
--- {MATCH:{5:%s+}|}
|
||||
---
|
||||
---]===])
|
||||
--- ```
|
||||
---
|
||||
--- An easy way to create an expect block is to call `snapshot` method
|
||||
--- on statusline where you'll call expect and run the test. It will print
|
||||
--- an expect block based on the state of statusline. You can copy it and
|
||||
--- replace the snapshot call with the expect call.
