Super-minimalistic testing framework to run in browser.

Install

1. Use UNPKG as a source

   <script
     type="module"
     data-latte-tests="./my.test.js"
     src="https://unpkg.com/@ludekarts/latte/dist/latte.min.js"
   ></script>
   

2. Install with NPM

   npm install @ludekarts/latte
   . . .
   
   <script
     type="module"
     data-latte-tests="./my.test.js"
     src="../node_modules/@ludekarts/latte/dist/latte.min.js"
   ></script>
   

Usage

On 📝 test.html include below

<script
  type="module"
  src="./latte.js"
  data-latte-tests="./my.test.js"
></script>

On 📝 my.test.js write test as usual:

describe("Sample tests", () => {

  it("Should be OK", () => {
    expect(1).to.have.equal(1);
  });

  it("Should fail", () => {
    expect(1).to.have.equal(2);
  });

});

To run only one test case follow code below:

only.it("Should run only this one", () => {
  expect(1).to.have.equal(1);
});
