MicroCoverage

MicroCoverage.jl is a code coverage tool for Julia, implemented in pure Julia.

Installation

julia> using Pkg; Pkg.add("MicroCoverage")

Example

Step 1: Create a file named foo.jl with the following contents:

function foo(x)
    if x == 1 || x == 100
        return "hello"
    else
        return "goodbye"
    end
end

Step 2: Create a file named test_foo.jl with the following contents:

using Test

@test foo(1) == "hello"

Step 3: Open julia and run the following commands:

julia> using MicroCoverage

julia> MicroCoverage.start("foo.jl")

julia> include("foo.jl")

julia> include("test_foo.jl")

julia> MicroCoverage.stop()

When you run MicroCoverage.stop(), MicroCoverage will create a file named foo.jl.microcov with the following contents:

[1,1,1]                 function foo(x)
[1,0,1,0,1]                 if x == 1 || x == 100
[1]                             return "hello"
-                           else
[0]                             return "goodbye"
-                           end
-                       end
-
