I have written a basic testing framework and am challenging myself to make a single page app in vanilla Javascript.
I've been struggling to work out why my test for view is not recognizing the 'list' constructor when I run it.
My specrunner has all the files loaded into it, and my previous tests on my model works fine. Also, imitating the test using the browser console in Specrunner gives the correct output as well.
Feel free to clone my repo if that is quicker here.
Note that my testing framework "espresso" uses expect in the place of assert and also has an extra parameter for the description of test.
espresso.js
var describe = function(description, test) {
document.getElementById("output").innerHTML +=
"<br><b>" + description + "</b></br>";
try {
test();
} catch (err) {
document.getElementById("output").innerHTML +=
"<br><li>error: " + err.message + "</li></br>";
console.log(err);
}
};
var expect = {
isEqual: function(description, first, second) {
if (first === second) {
document.getElementById("output").innerHTML +=
description +
"<br><li><font color='green'>PASS: [" +
first +
"] is equal to [" +
second +
"]</li></br>";
} else {
document.getElementById("output").innerHTML +=
"<br><li><font color='red'>FAIL: [" +
first +
"] is not equal to [" +
second +
"]</li></br>";
}
}
}

})(this);
model-test.js
describe("List #initialize", function() {
var list = new List();
expect.isEqual("blank array is loaded", list.notelist.length, 0);
});
describe("List #add", function() {
var list = new List();
list.add("hello");
expect.isEqual(
"can create and store a note",
list.notelist[0].show(),
"hello"
);
list.add("goodbye");
expect.isEqual(
"second note says goodbye",
list.notelist[1].show(),
"goodbye"
);
expect.isEqual("there are two notes in the list", list.notelist.length, 2);
});
view-tests.js (the failing test)
describe("View #convert", function() {
var view = new View();
expect.isEqual(
"converts the note into a HTML list",
view.convert(list.notelist),
"<br><ul>hello</ul></br>"
);
});
Thanks in advance.
