jest-skip-if v0.1.0

jest-skip-if

This package is created to handle the use case when you need to conditionally skip or test a spec in jest.

Installation

yarn add --dev jest jest-skip-if 

Setup

With jest-skip-if installed you can either use it on individual files or add it globally.

For individual files you can import and use it directly.

import {skipIf} from 'jest-skip-if';

skipIf(true, 'skipped spec', () => {})

Or, if desired it can be setup globally by adding or modifying a setup script with Jest's setupFilesAfterEnv configuration.

// testSetup.js
import {skipIf, testIf} from 'jest-skip-if';

global.skipIf = skipIf;
global.testIf = testIf;

"jest": {
  "setupFilesAfterEnv": ["./testSetup.js"]
}

If desired, you can also add jest-skip-if setup file to your setupFilesAfterEnv array.

"jest": {
  "setupFilesAfterEnv": ["jest-skip-if/setup"]
}

Helpers

skipIf

When there is a use case that you need to skip a spec based off of a condition you can use skipIf

skipIf(hasFeatureEnabled, 'spec using feature', () => {
  // Nothing is run given hasFeatureEnabled is true
  expect(true).toBe(true);
})

In the example, hasFeatureEnabled can be both a boolean or a function returning a boolean.

testIf

When there is a use case that you need to test a spec based off of a condition you can use testIf

testIf(hasFeatureEnabled, 'spec using feature', () => {
  // Spec is run given hasFeatureEnabled is true
  expect(true).toBe(true);
})

In the example, hasFeatureEnabled can be both a boolean or a function returning a boolean.
