Overview

- -

-LuaCov is a simple coverage analyzer for Lua -scripts. When a Lua script is run with the luacov module loaded, it -generates a stats file with the number of executions of each line of the -script and its loaded modules. The luacov command-line script then -processes this file generating a report file which allows one to visualize -which code paths were not traversed, which is useful for verifying the -effectiveness of a test suite. -

- -

-LuaCov is free software and uses the same license as Lua. -

- -

Download

- -

-LuaCov can be downloaded from its -LuaForge page. -

- -

-LuaCov is written in pure Lua and has no external dependencies. -

- -

Instructions

- -

-Using LuaCov consists of two steps: running your script to collect -coverage data, and then running luacov on the collected data to -generate a report. -

- -

-To collect coverage data, your script needs to load the luacov -Lua module. This can be done from the command-line, without modifying -your script, like this: -

- -
-lua -lluacov test.lua -
- -

-(Alternatively, you can add require("luacov") to the first line -of your script.) -

- -

-Once the script is run, a file called lcov.stats.out is generated. -If the file already exists, statistics are added to it. This is useful, -for example, for making a series of runs with different input parameters in -a test suite. To start the accounting from scratch, just delete the stats file. -

- -

-To generate a report, just run the luacov command-line script. -It expects to find a file named lcov.stats.out in the current -directory, and outputs a file named lcov.report.out. -

- -

This is an example output of the report file:

- -
-============================================================
-../test.lua
-============================================================
-
-        -- Which branch will run?
-1       if 10 > 100 then
-0          print("I don't think this line will execute.")
-0       else
-1          print("Hello, LuaCov!")
-1       end
-
- -

-Note that to generate this report, luacov reads the source files. -Therefore, it expects to find them in the same location they were when -the luacov module ran (the stats file stores the filenames, but -not the sources themselves). -

- -

-LuaCov saves its stats upon normal program termination. If your program -is a daemon -- in other words, if it does not terminate normally -- you -can use the luacov.tick module, which periodically saves the -stats file. For example, to run (on Unix systems) LuaCov on -Xavante, -just modify the first line of xavante_start.lua so it reads: -

- -
-#!/usr/bin/env lua -lluacov.tick -
