I am new to cypress and I want to write unit tests for my existing application. Can anyone suggest how to write unit tests for angular js using cypress and code coverage?
I have followed the documentation but I am not getting combined results. The code coverage index file is showing only spec files.

You can use these plugins:
For angular
https://github.com/bahmutov/cypress-angular-unit-test
https://github.com/bahmutov/cypress-angularjs-unit-test
For code coverage
https://github.com/cypress-io/code-coverage
I also recommend that you read this article:

I noticed in cypress documentation that we can use Cypress for testing components. But i did not find any info regarding using cypress to test simple javascript functions like:
function isObjectLike(value) {
return value != null && typeof value == 'object' && !Array.isArray(value);
}
In my situation i am using cypress to test Nextjs application. I test my components with unit tests and also for integration tests. So all my tests are visual tests. I want also to tests my utlis/helpers functions using unit tests. Question: Could i do this with cypress or it is not designed for what i want to do?
Conventionally Cypress was designed to run test in browser environment, and it has tools which helps this purpose. For the most time, for unit testing your functions you'd rather want to use JavaScript test runner like Jest.
However, according to Cypress documentation, there are cases when you would want to do unit tests in this framework: for example if you want to test if some property is present on your window object. See example.
Bottom line: Pure JavaScript test runners have more tools and are probably better for unit testing functions.
I've read ton's of tutorials, but I must admit that this testing stuff is still very confusing to me. I have a Nw.js app which (of course) uses NodeJS and also Angular. I've installed the Jasmine test framework globally via npm and wrote an example test which starts with the following lines, and placed it in the spec sub-directory:
describe ( 'Test for my controller', function () {
beforeEach ( module ('module_under_test') );
... and so on ...
});
When running the test by typing jasmine on the cmd line (from the root folder of the app), I get the following error message:
TypeError: module is not a function
I know that I have to include the Angular library somehow. But where? In a normal browser application, it is included in the HTML <script> tag, but I don't have this possibility. I also know that I could write a HTML file, which shows the Jasmine result page after tests have finished, but I would prefer to start Jasmine on the cmd line.
First I thought about adding the angular library to the "helpers" entry in jasmine.json. But it didn't work. The documentation of this file is unfortunately very poor. In the Angular documentation and tutorials it is always mentioned to use Karma. But my understanding is that Karma is only useful for testing with browsers, since it spawns an own webserver. This does not make sense in my case.
Would be great if somebody could give me a hint, thanks!
I am configuring my application developed on Ionic 2 with Angular 2 and TS to generate code coverage reports generated for my test files.
I am using Jasmine , Karma and remap-istanbul for Unit Testing and generating coverage reports.
refering to this wonderful post: twofuckingdevelopers.com/2016/01/testing-angular-2-with-karma-and-jasmine/
However, I am not able to list out files that do not have a spec file written for them. Is there a way to include the same in istanbul reports and generate overall coverage accordingly.
Thank You!!!
In your Karma config file set the following option:
coverageReporter: {
includeAllSources: true
}
I am using Angular (1.x) with Browserify, and Jasmine as test framework. I would like to run code coverage test. I researched online and it's a little here and there and some of the examples doesn't work. I was wondering if any people have the experience setting the code coverage test for angular+browserify+jasmine ? and if there's a repo in github i can reference?
Use karma-coverage. Check out my karma playground here: https://github.com/marcinmierzejewski1024/jasmine-karma-playground. It's propably based on istanbul(generated reports looks very similar) but I am not 100% sure
We can test normal JavaScript code in the browser using only Jasmine (by only I mean without Karma or any other test runners or nodejs).
Can we do this for AngularJS projects as well? If yes, how?
Sure. It's exactly the same like with plain js. You just need to use the methods for angular testing.
