# testEach

To make testing a lot of combinations easy.

Define the inputs and required outputs, write the test logic once, and let `testEach` run each case for you separately.

You can add descriptions to each `TestCase`, so you can use them in assertions, `async` test functions are also supported.

## Usage

```ts

import { TestCase, testEach } from "https://deno.land/x/[email protected]/mod.ts";

testEach<{a: number, b: number}, number>(

  "Quick math",

  [

    { input: { a: 1, b: 3 }, result: 3, desc: '1*3 should equal 3'},

    { input: { a: 2, b: 3 }, result: 6, desc: '2*3 should equal 6' },

    { input: { a: 3, b: 3 }, result: 9, desc: '3*3 should equal 9' },

    { input: { a: 4, b: 3 }, result: 12, desc: '4*3 should equal 12' },

  ],

  (testCase) => {

    assertEquals(

      testCase.input.a * testCase.input.b,

      testCase.result,

      testCase.desc,

    );

  },

);

testEach(

  "Exceptions",

  [

    { input: false, exception: { msg: "my exception" } },

    { input: 5, result: 12 },

  ],

  (testCase) => {

    if (typeof testCase.input === "number") {

      assertEquals(60 / testCase.input, testCase.result);

    } else {

      throw new Error("my exception");

    }

  },

);

testEach(

  "Options",

  [/*...*/],

  (testCase) => {/* ... */ },

  {only: true, ignore: true, sanitizeOps: true, sanitizeResources: true}

);

```
