BDD wrappers for jasmine and mocha describe/it to help writing tests in GIVEN WHEN THEN AND fashion so you can write:
GIVEN("a gremlin", function () {
WHEN("I feed it", function () {
beforeEach(function () {
gremlin.feed();
});
THEN("is happy", function () {
expect(gremlin.happy).to.be.true;
});
AND("I give it water", function () {
beforeEach(function () {
gremlin.water();
});
THEN("they are all happy", function () {
expect(gremlin[0].happy).to.be.true;
expect(gremlin[1].happy).to.be.true;
expect(gremlin[2].happy).to.be.true;
expect(gremlin[3].happy).to.be.true;
});
});
WHEN("it's past midnight", function () {
beforeEach(function () {
time.set('0000');
gremlin.feed();
});
THEN("it's not cute anymore", function () {
expect(gremlin.cute).to.be.false;
});
});
});
});Instead of:
describe("GIVEN a gremlin", function () {
describe("WHEN I feed it", function () {
beforeEach(function () {
gremlin.feed();
});
it("THEN is happy", function () {
expect(gremlin.happy).to.be.true;
});
describe("AND I give it water", function () {
beforeEach(function () {
gremlin.water();
});
it("THEN they are all happy", function () {
expect(gremlin[0].happy).to.be.true;
expect(gremlin[1].happy).to.be.true;
expect(gremlin[2].happy).to.be.true;
expect(gremlin[3].happy).to.be.true;
});
});
describe("WHEN it's past midnight", function () {
beforeEach(function () {
time.set('0000');
gremlin.feed();
});
it("THEN it's not cute anymore", function () {
expect(gremlin.cute).to.be.false;
});
});
});
});When a test fails, the trace will correctly output GIVEN a gremlin WHEN I feed it THEN is happy.
npm install bdd-wrappersThis will add the GIVEN, WHEN, AND, THEN functions to the global object
require("bdd-wrappers");
GIVEN(...);You can also define your own wrappers. The first parameter is a string and will prefix the string describing the test.
var wrap = require("bdd-wrappers").wrap;
// A wrapper for it(...);
GLOBAL.SHOULD = wrap("SHOULD ", it);
// So:
SHOULD("do something", func);
// will ouput: SHOULD so something
// A wrapper for describe(...);
GLOBAL.OR = wrap("OR ", describe);MIT
