API

Custom Configuration

Cloning configuration from config/config.js of shopback-test module as a custom configuration in your Nodejs project, then change the value of properties as you desire. If no custom configuration isn't given, the default configuration in the module will be used instead.

const { Validator, InputType, OutputType } = require('shopback-test');
const config = require('./config');
const validator = new Validator(config);

Rule

const {
    TagExistenceRule,
    TagExistenceWithAttrRule,
    TagLimitCountRule,
    TagWithoutAttrCountRule
} = require('shopback-test');

new TagExistenceRule('head', 'title');
new TagExistenceWithAttrRule('head', 'img', 'alt');
new TagExistenceWithAttrRule('head', 'meta', 'name', 'description');
new TagLimitCountRule('', 'strong', 15);
new TagLimitCountRule('', 'h1', 1);
new TagWithoutAttrCountRule('', 'img', 'alt');
new TagWithoutAttrCountRule('', 'a', 'rel');

// Add rules
validator.addRule(new TagExistenceRule('head', 'title'));
validator.addRule(new TagExistenceWithAttrRule('head', 'img', 'alt'));

Input

There are 2 input types: FILE and STREAM. By default FILE, only invole setInput method of Validator in case of changing the input type. The input path is configured in the config.js file by input_path.

const { InputType } = require('shopback-test');
validator.setInput(InputType.FILE); // or InputType.STREAM.

Output

There are 3 output types: CONSOLE, FILE and STREAM. By default CONSOLE, only invole setOutput method of Validator in case of changing the output type. The output path is configured in the config.js file by output_path.

const { OutputType } = require('shopback-test');
validator.setOutput(OutputType.FILE);

Validator

constructor(skipPredefinedRules)

All predefined rules is by default added (skipPredefinedRules = false)

const { Validator } = require('shopback-test');
const validator = new Validator(true); // skip all predefined rules

skipRules(indexes)

Skip one-index based rules

validator.skipRules([1,4,5]);

addRule(rule)

validator.addRule(new RuleExistTag('head', 'title'));

validate() && getResult()

validator
  .validate()
  .then(async () => await validator.getResult())
  .catch(err => console.error(err));

Custom Rules

const { Rule } = require('shopback-test');

class NewRule extends Rule {
  constructor(rootTag, ...params) {
    super(rootTag);
    ...
  }

  validate() {
    // Write logic
    this.isValid = true; // or false
  }

  error() {
    return !this.isValid ? `Error message` : '';
  }
}

validator.addRule(new NewRule(rootTag, ...params));

Unit testing

Run npm test or mocha .\test\*\*test.js in the shopback-test module.
