gpc-filter

gpc-filter

The Filter precompiler is responsible for including or excluding the elements of a feature file in the result, which match a cucumber-tag-expression (e.g., has a given tag, does not have a given tag)

Usage

'use strict';
const compiler = require('gherking');
const Filter = require('gpc-filter');

let ast = await compiler.load('./features/src/login.feature');
ast = compiler.process(
    ast,
    new Filter({
        // config
    })
);
await compiler.save('./features/dist/login.feature', ast, {
    lineBreak: '\r\n'
});

'use strict';
import {load, process, save} from "gherking";
import Filter = require("gpc-filter");

let ast = await load("./features/src/login.feature");
ast = process(
    ast,
    new Filter({
        // config
    })
);
await save('./features/dist/login.feature', ast, {
    lineBreak: '\r\n'
});

Configuration

The precompiler accepts the following configuration:

Type	Description	Necessity	Default value
string	Cucumber-tag-expression the filtering is based on	Optional	not @wip

Example

Keeping elements with @current tag

new Filter("@current")

Scenario: One tag
    Given A scenario with one tag is created
    When this Scenario is compiled
    Then something should happen

@current
Scenario: Another tag
    Given A scenario with another tag is created
    When this Scenario is compiled
    Then something should happen

Scenario Outline: Multiple tags in multiple examples
    Given A scenarioOutline with tags in multiple examples is created
    When this Scenario Outline is compiled
    Then something should happen

    Examples:
        | multiple examples no tag column |
        | multiple examples no tag row    | 
        
    @wip    
    Examples:
        | multiple examples one tag column |
        | multiple examples one tag row    |

    @current
    Examples:
        | multiple examples other tag column |
        | multiple examples other tag row    |

Will be processed into:

@current
Scenario: Another tag
    Given A scenario with another tag is created
    When this Scenario is compiled
    Then something should happen

Scenario Outline: Multiple tags in multiple examples
    Given A scenarioOutline with tags in multiple examples is created
    When this Scenario Outline is compiled
    Then something should happen

    @current
    Examples:
        | multiple examples other tag column |
        | multiple examples other tag row    |
