@power-doctest/core v5.3.4

@power-doctest/core

power-doctest core library.

Features

• Convert Code to power-doctest ready code.
• power-doctest use comment-to-assert and power-assert

Installation

npm install @power-doctest/core

Usage

power-doctest convert following code

function sum(ary) {
    return ary.reduce(function (current, next) {
        return current + next
    }, 0);
}

var total = sum([1, 2, 3, 4, 5]);
total; // => 5

to

var assert = require('power-assert');
function sum(ary) {
    return ary.reduce(function (current, next) {
        return current + next;
    }, 0);
}
var total = sum([
    1,
    2,
    3,
    4,
    5
]);
assert.equal(assert._expr(assert._capt(total, 'arguments/0'), {
    content: 'assert.equal(total, 5)',
    line: 14
}), 5);
//# sourceMappingURL=data:application/json;base64,eyJ2ZXJzaW9uIjozLCJzb3VyY2VzIjpbXSwibmFtZXMiOltdLCJtYXBwaW5ncyI6IiIsInNvdXJjZXNDb250ZW50IjpbXX0

And execute this transformed code:

$ node example/transformed.js
AssertionError:   # at line: 14

  assert.equal(total, 5)
               |
               15

API

• convertCode: Convert code to code
• convertAST: Convert Babel's AST to AST

import { ParserOptions } from "@babel/parser";
import { File } from "@babel/types";
export interface convertCodeOption {
    filePath: string;
    babel?: ParserOptions;
    assertBeforeCallbackName?: string;
    assertAfterCallbackName?: string;
}
/**
 * Convert Code to Code
 * @param code
 * @param options
 */
export declare function convertCode(code: string, options: convertCodeOption): string;
export interface convertASTOptions {
    assertBeforeCallbackName?: string;
    assertAfterCallbackName?: string;
    filePath: string;
}
/**
 * Convert AST to AST
 * @param AST
 * @param options
 */
export declare function convertAST<T extends File>(AST: T, options: convertASTOptions): T;

Exception Test

Look like => Error is assert.throw().

throw new Error(); // => Error
var object = {};
obj.not.found; // => Error

Covert this case to:

var assert = require('power-assert');
assert.throws(function () {
    throw new Error();
}, Error);
var object = {};
assert.throws(function () {
    object.not.found;
}, Error);
