nim-sections

Provides Section macro and its Given, When, Then aliases. Nested Section blocks are converted into separate local branches of execution. Inspired by C++ Catch Test Framework sections

Installation

nimble install sections

Example

Following

Section:
    var s = ""
    s &= "a"
    Section:
        s &= "b"
    Section:
        s &= "c"
    echo s

Will be converted to

block:
    var s = ""
    s &= "a"
    block:
        s &= "b"
    echo s

block:
    var s = ""
    s &= "a"
    block:
        s &= "c"
    echo s

BDD style example

import unittest
import sections

test "For README.md":
    Given:
        var s:string = ""
        s &= "a"
        When:
            s &= "b"
            Then:
                echo s
                check s=="ab"
        When:
            s &= "c"
            Then:
                echo s
                check s=="ac"

Tested with

• nim v 0.12

ToDo

• allow optional string argument
• current implementation works only when Section blocks are in direct parent/child structures, deep nesting support is planned in future
