Crafty comes with a crafty test
command by default, but no test runner comes
built-in.
For that we made an integration with Jest.
Installing
cd src/main/frontend
npm install @swissquote/crafty @swissquote/crafty-preset-jest --save
In your crafty.config.js
file, you must add the following presets
module.exports = {
presets: ["@swissquote/crafty-preset-jest"]
};
Your first test
in js
create a file named math.js
module.exports.add = function add(a, b) {
return a + b;
};
module.exports.multiply = function multiply(a, b) {
return a * b;
};
then in js/__tests__
create another file named math.js
const math = require("../math");
test("adds 1 + 2 to equal 3", () => {
expect(math.add(1, 2)).toBe(3);
});
test("multiply something", () => {
expect(math.multiply(2, 2)).toBe(4);
});
You can now run crafty test
and see that the test is discovered and executed
automatically.

With Babel or Typescript
You can also use EcmaScript 2015+ and TypeScript features by installing and adding their respective presets.
They are configured automatically once you include them in presets
from your
crafty.config.js
