I am working my way through a node course, and I want to stop before I go any further and add testing to it.
ATM I'd just like to be able to test the home route kicks back a 200. With postman it does no problem, but I can't get mocha to test it.
app.js:
const express = require("express");
const session = require("express-session");
const mongoose = require("mongoose");
const MongoStore = require("connect-mongo")(session);
const path = require("path");
const cookieParser = require("cookie-parser");
const bodyParser = require("body-parser");
const passport = require("passport");
const { promisify } = require("es6-promisify");
const flash = require("connect-flash");
const expressValidator = require("express-validator");
const routes = require("./routes/index");
const helpers = require("./helpers");
const errorHandlers = require("./handlers/errorHandlers");
// create our Express app
const app = express();
// view engine setup
app.set("views", path.join(__dirname, "views")); // this is the folder where we keep our pug files
app.set("view engine", "pug"); // we use the engine pug, mustache or EJS work great too
// serves up static files from the public folder. Anything in public/ will just be served up as the file it is
app.use(express.static(path.join(__dirname, "public")));
// Takes the raw requests and turns them into usable properties on req.body
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
// Exposes a bunch of methods for validating data. Used heavily on userController.validateRegister
app.use(expressValidator());
// populates req.cookies with any cookies that came along with the request
app.use(cookieParser());
// Sessions allow us to store data on visitors from request to request
// This keeps users logged in and allows us to send flash messages
app.use(
session({
secret: process.env.SECRET,
key: process.env.KEY,
resave: false,
saveUninitialized: false,
store: new MongoStore({ mongooseConnection: mongoose.connection })
})
);
// // Passport JS is what we use to handle our logins
app.use(passport.initialize());
app.use(passport.session());
// // The flash middleware let's us use req.flash('error', 'Shit!'), which will then pass that message to the next page the user requests
app.use(flash());
// pass variables to our templates + all requests
app.use((req, res, next) => {
res.locals.h = helpers;
res.locals.flashes = req.flash();
res.locals.user = req.user || null;
res.locals.currentPath = req.path;
next();
});
// promisify some callback based APIs
app.use((req, res, next) => {
req.login = promisify(req.login, req);
next();
});
// After allllll that above middleware, we finally handle our own routes!
app.use("/", routes);
// If that above routes didnt work, we 404 them and forward to error handler
app.use(errorHandlers.notFound);
// One of our error handlers will see if these errors are just validation errors
app.use(errorHandlers.flashValidationErrors);
// Otherwise this was a really bad error we didn't expect! Shoot eh
if (app.get("env") === "development") {
/* Development Error Handler - Prints stack trace */
app.use(errorHandlers.developmentErrors);
}
// production error handler
app.use(errorHandlers.productionErrors);
// done! we export it so we can start the site in start.js
module.exports = app;
The application is set up to run routes through a file at routes/ called index.js. That file then calls up the view file...
My test can't seem to get properly routed though.
const expect = require("expect");
const request = require("supertest");
const app = require("./../../app");
describe("Dummy Test", () => {
it("Should return 5", () => {
const result = 2 + 3;
expect(5);
});
});
describe("Get /home", () => {
it("should get home", done => {
request(app)
.get("/home")
.expect(200)
.end(done);
});
});
It always returns a 500. I can make the repo public if a deeper look might help.
