This is one tiny implementation of jasmine, which is runnable in the browser environment. I create this tiny rudimentary 'jasmine framework' basically for fun and to have a jasmine runnable in browser with the minimum codes that I can write.
By now, you should, however, only deploy it under the browser environment(for the name) and might refer to your old friend JavaScript DevTools Console(i.e., F12 in some browsers) to observe the resulting record.
describe("Testing", function() {
var share;
beforeEach("BeforeEach: Sharing Value", function() {
share = 18;
expect(share).toBe(0);
});
it("the first: Synchronousity", function() {
var num = 1;
expect(share++).toBe(18);
expect(num).toBe(1);
});
it("the second: Asynchronousity", function(done) {
var called = false;
setTimeout(function() {
called = true;
expect(share).toBe(18);
expect(called).toBe(false);
done();
}, 0);
expect(called).toBe(false);
});
it("the third: Object", function() {
var arr = {a:1, b:2};
expect(arr).toEqual({a:1, b:3, c:5});
});
// createSpy & toHaveBeenCalledWith is in development
});Global callbacks will be called if they are present, on tests complete:
// when all tests pass:
window.jasmineBrowserSuccessCallback();
// when one or more test fail:
window.jasmineBrowserErrorCallback();
This module is orginally coded for fun & exploration, hence the features are quite limited. The current features only include:
- basic support of
describe,expect&it, just like jasmine. - support the asynchronous test.
While I have not sketched out the other APIs akin to original 'jasmine' at a higher level yet, you should aware that they actually exsit and will soon be brought together in future version. What the current state of codes stands out is merely an attempt to prove the viability of a variant implementation of jasmine. I try to not go any futher beyond the basic mocking features jasmine provided, those advanced features like createSpy, toHaveBeenCalled and toHaveBeenCalledWith are just not available in current version.
To put an advertisement, there is another brother module I am working on(jasmine-node), this ongoing module is able to perform jasmine test in node.js with a silimar implementation of this 'jasmine-browser'(hint: it uses the node process.nextTick for a pollyfill).
There is no supports of gulp, browserify and webpack in current version, but I think they will all come out in future version(believe me). For now, suffice it to enjoy the poor interfaces I've just implemented.
Stay tuned~
