jasmine-data_driven_testing

With this TypeScript plugin for Jasmine 5.x, data-driven testing is very easy.

Contents

With this package you can run data-driven Jasmine tests for your TypeScript code. The output is displayed in your terminal by default.

Quick Start

Installation:

• First install Jasmine as described at jasmine.

• Then jasmine-data_driven_testing is installed with:

  npm install --save-dev jasmine-data_driven_testing

Write your first test:

import { all } from "jasmine-data_driven_testing";

describe("blank values are invalid", function () {
    all<any>([
        [""],
        [null],
        [undefined]
    ], "blank values are invalid", function (param: string) {
        // act
        let isBlank: boolean = true;
        if (param) {
            isBlank = false;
        }
        // assert
        expect(isBlank).toBe(true);
    });
}

Getting Started

Simply import { * } from "jasmine-data_driven_testing";. Now you have three functions available to you:

Data Drive Tests:

all(description, dataset, callback);

Data Driven Tests, marked as pending:

xall(description, dataset, callback);

Data Driven Tests, marked as focused:

fall(description, dataset, callback);

Data Driven Tests

Data Driven Tests have three basic components:

1. The description
2. The dataset, which is an array of arguments passed to the spec function
3. The spec function

A quick example:

import { all } from "jasmine-data_driven_testing";

describe("blank values are invalid", function() {
    all<any>([
        [""],
        [null],
        [undefined]
    ], "blank values are invalid", function(value) {
            expect(isEmpty(value)).toBe(true);
    });
}

The call to all above is equivalent to these native Jasmine method calls:

describe("blank values are invalid", function() {
 
    it('blank values are invalid Nr. 1 ("")', function() {
        expect(isEmpty("")).toBe(true);
    });
 
    it('blank values are invalid Nr. 2 (null)', function() {
        expect(isEmpty(null)).toBe(true);
    });
 
    it('blank values are invalid Nr. 3 (undefined)', function() {
        expect(isEmpty(undefined)).toBe(true);
    });
 
});

While the all method is extended to the Jasmine it method, the xall method is extended to the xit method and the fall method is extended to the fit method.
